SES Reference
1. Autonomous Behavior
1.1 SCSI Enclosure Processor
1.1
SCSI Enclosure Processor
All expanders inclduded in each IOM/HEM pair operate as a single entity known as the SCSI Enclosure
Processor (SEP). The SEP is the virtual device that implements all SES functionality defined by this
document, including:
• Enclosure management policy
• Status gathering
• Parsing and building SES pages
• Communicating with enclosure management components (LEDs, fans, power supplies, sensors, etc.)
• Staggering drive spin-up
• Enabling/disabling attached PHYs
• Handling zoning requests
1.2
Offline State
The enclosure has the ability to enter offline state. The offline state is designed to protect the enclosure and
its data, along with the larger data center ecosystem, against cases of serious risk of data or SAS fabric
corruption if the enclosure were to attempt to operate.
During offline state, the drives are powered off and are not presented to hosts. This leaves the SEP as the
only SAS target in the enclosure. In the offline state, the SEP fully responds to host commands other than
those that would cause the disk drives to be powered on or presented to hosts. The offline state is volatile,
and will not automatically recur after an enclosure reset or power cycle unless, the conditions which warrant
it, reoccur.
There are several conditions which can cause a SEP to enter offline state, including:
• Enclosure VPD data unreadable or corrupted
• Enclosure is in thermal compromise state – see Thermal Offline State (page 4)
• SEP cannot communicate with all expanders in the design
The exact reason for the particular state is reported in the Help Text Diagnostic Page (03h) (page 39) and
String Out/In Diagnostic Page (04h) (page 40).
1.3
SAS Fabric Management
The SEP autonomously performs the following functions relative to SAS fabric management:
• Configures SAS PHYs to appropriate transceiver settings
• Programs each expander with a unique SAS address from Enclosure VPD data
• Provides appropriate branding-specific Inquiry data from Enclosure VPD data
• Provides SMP initiator and target services on all expanders
• Exposes a virtual SSP initiator and target services on the primary expander only
• Enables physical layers connected to drives and host cables only if a drive/cable is connected
1.4
Drive Spin-up Staggering
When the enclosure is powered-on, all drives are automatically spun-up per the following algorithm, to avoid
drawing an excessive amount of current:
2
SES Reference
1. Autonomous Behavior
1.5 Event Logging
1. 0.5-second initial delay
2. 2 drives spun up every second until all have spun up
1.5
Event Logging
The SEP has a non-volatile event logging subsystem contained in expander-level VPD EEPROM. Entries
are time-stamped with an incrementing tick counter, or time of day in the server environment, where RTC is
available.
Entries are logged to indicate a variety of events, including:
• SEP boot events
• Entry or exit from offline state
• CRU configuration changes
• Code updates
• Crash records
Note: The event log buffer erases the oldest entries when it is full.
1.6
Host, Drive, and Interconnect Port Management
The SCSI Enclosure Processor (SEP) monitors the PHYs which connect the Serial Attached SCSI (SAS)
expanders to other devices. The monitoring indicates link up, link down, and link partial up status. A partial
link up status condition means that not all of the PHYs in a wide port have achieved linked status or not all of
the PHYs in a wide port are linked at the same link rate.
Host port interconnect link status issues are signaled using the host port light-emitting diodes (LED), and
by marking the corresponding SCSI Enclosure Services (SES) SAS Connector Element instance with Non-
Critical or Critical status.
Drive interconnect link status issues are signaled using the drive LEDs, and by marking the corresponding
SES Array Device Slot Element instance with Non-Critical or Critical status.
Expander interconnect link status issues are signaled using the chassis and HEM LEDs, and by marking the
corresponding SES SAS Expander Element instance with Non-Critical or Critical status.
1.7
Thermal Management
1.7.1
Closed Loop Fan Algorithm
The SCSI Enclosure Processor (SEP) periodically polls the current readings of both enclosure and drive
temperature sensors. It automatically adjusts the fan pulse-width modulation (PWM) values to the minimum
necessary air flow that maintains all enclosure component temperatures, including drives, at or below a
factory-set level across the ambient temperature range allowed for the product. The algorithm incorporates
both time- and temperature-based hysteresis to avoid over-compensation phenomena.

SES Reference
1. Autonomous Behavior
1.7 Thermal Management
1.7.2
Thermal Compromise Handling
In the event that the enclosure becomes thermally compromised, the fans will run at full speed regardless
of temperature readings. An example of an enclosure becoming thermally compromised is missing a
required customer replaceable unit (CRU), or another serious fault.
1.7.3
Thermal Offline State
If the enclosure temperature readings exceed critical values for a period of time that constitutes a risk to
continued safe operation, the enclosure enters an offline state. In an offline state, one or more drives are
taken offline. This might mean that they are spun down and powered off. The host may continue to send
and receive SCSI Enclosure Services (SES) diagnostic pages in offline state, however the SCSI Enclosure
Processor (SEP) rejects SCSI Enclosure Services (SES) requests to power up drives that have been taken
offline.
Note: The thermal shutdown condition self-resolves once temperatures have reached a safe
level.
1.7.4
Enclosure Shutdown
Certain classes of thermal fault conditions require the enclosure to autonomously shut down as much of
the enclosure as possible. If this occurs, the enclosure will return to low-power state. The host may continue
to send and receive SCSI Enclosure Services (SES) diagnostic pages in low-power state, but this condition
does not self-resolve. The intent is that user intervention follows to ascertain and mitigate the reason for the
shutdown.

SAS Topology
The SAS Topology of the Data60 3000 Series is shown in the following Figure 1: SAS Topology (page 6)
figure. The architecture provides six (6) x4 MiniSAS HD port host connections to the HEM. These ports can
be used with standard cables to connect to the MiniSAS HD port located on an arbitrary third party SAS
host. The availability of six (6) MiniSAS HD ports on the HEM permits daisy-chained topologies.

SG3 Utilities
The sg3_utils package contains utilities that send SCSI commands to devices. Sg3_utils are available for
Linux and Windows platforms and can be obtained from http://sg.danny.cz/sg/sg3_utils.html. The SG3
Element Index values—provided in the tables throughout the remainder of this document—can be used with
the sg_ses command to obtain data for the specific element instance. For example, sg_ses /dev/sg2 --
page=2 --index=0,3 retrieves information for drive 4, and so on.
It is recommended that the Data60 3000 Series be used with V1.47 or later of the SG3 distribution, as this
release fixes several known issues in previous releases.

Note: During service events—when a drive is hot plugged or replaced and the drive installed
properly—the LED state of that drive slot will change to solid ON. This is to provide the user
with visual feedback that the drive has been successfully connected and has been discovered
by the expander. Once the enclosure has been slid back into the rack, and the OPEN bit on
the door sensor element changes from 1 to 0, the LED will return to the previously set state
(Ident, Fault, or Off).

Report General
The response frame for Serial Management Protocol (SMP) Report General contains a field labeled
NUMBER OF PHYS, which is intended to indicate the total number of PHYs supported by the responding
expander.
In the Data60 3000 Series, the NUMBER OF PHYS reported varies by expander, as follows:
• The HEM expander reports the physical PHY count.
• The DRV1 expander reports two (2) extra PHYs, since the SSP Target is on the second of four (4) virtual
PHYs that exist on the 24G expanders.
3.3
Report Manufacturer Information
The response frame for SMP Report Manufacturer Information reports the firmware revision of the
expanders in the vendor unique field located in bytes 52-59.
3.4
PHY Control
It is not recommended that hosts manipulate the PHY-enabled states. The SCSI Enclosure Processor (SEP)
intends to manage PHY enable and disable operations autonomously.
3.5
Zoning Support
The SCSI Enclosure Processor (SEP) implements T10 defined Serial Management Protocol (SMP) controlled
zoning, and has the capability to save the host-defined zoning parameters in non-volatile memory.
The SEP’s zoning capability limits the ability of the host to discover and communicate in-band with specific
drives. Zoning is not designed to limit the SEP’s ability to manage drives or drive slots, nor does it limit the
ability of SCSI Enclosure Services (SES) clients of the SEP to manage drives. All installed drives and drive
slots are exposed through the SES management interface, to all host clients, regardless of the currently
active zoning configuration.

4.1 SES Model
4.1
SES Model
The SCSI Enclosure Processor (SEP) follows the Standalone Enclosure Services Process model described
in the SCSI Enclosure Services (SES) standard. Each enclosure’s SEP performs SES management
independently of other enclosures that are connected together within a Serial Attached SCSI (SAS) domain.
Each SEP manages only the SES elements located inside the local enclosure. Each enclosure reports the
topology as a single primary sub-enclosure as defined by the SES standard.
The SEP does not support dynamic changes to the reported configuration. As a result, the SEP always
reports a fixed GENERATION CODE of 00000000h.
4.1.1
Sequencing of SCSI Operations
Control Diagnostic Page Requests
Hosts can send SCSI Enclosure Services (SES) control diagnostic page requests to perform a variety of
operations, including:
• Requesting light-emitting diode (LED) flash patterns
• Recording predicted, known component failures
• Requesting power cycle of one or more drives
• Code download
All control operations follow a synchronous completion model. For example, the SEP will send SCSI status
only when the requested operation has been completed, or to notify the host that the requested operation
cannot be performed.
Status Diagnostic Page Requests
Hosts can request SES status diagnostic pages that contain customer replaceable unit (CRU) information,
including:
• Drive presence
• Health information
• SAS topology maps
• Temperatures
• Fan speeds
• Voltages
• Currents
These operations follow a non-blocking completion model. For example, the SEP returns the last known
status, rather than blocking the completion of the SCSI operation, and doing an immediate polling operation
before replying.
4.1.2
Reserved Bit Checking
The SCSI Enclosure Processor (SEP) parses received SCSI Enclosure Services (SES) control pages to
validate that no reserved bits are set. If one or more reserved bits are set, the command is terminated with:
• A Check Condition status
• A sense key of Illegal Request/Invalid Field in Parameter List
21
SES Reference
4. SES Diagnostic Pages
4.2 SES Supported Diagnostics Page (00h)
• The byte/bit location of the first illegal set bit reported in the SKS field portion of the sense data
In this case, no portion of the rejected SES control request is acted upon. The SEP then discards valid
portions of the page that occur before or after the illegal set bit.
Note: If a SES control page sets a bit that is supported by T10, but is unsupported by the SEP,
the SEP will ignore it.
4.1.3
Partial SCSI Enclosure Services Pages
A host may send a partial SCSI Enclosure Services (SES) control page. The SCSI Enclosure Processor
(SEP) will parse and consume as much of the page as is indicated by the PAGE LENGTH field in the page.
A host may request a partial SES status page. The SEP will return the page as requested, up to the smaller
of the specified Command Descriptor Block (CDB) allocation length, or the size of the available data.
4.1.4
Predictive Failure
The SCSI Enclosure Processor (SEP) of the Data60 3000 Series platform does not provide predictive
failure capabilities for enclosure components. Future generations of the platform may support the ability to
predict the failure of drives connected to Array Device Slot element instances.
Hosts may designate an element instance as failed or predicted to fail by sending an appropriate SCSI
Enclosure Services (SES) control request.

The Enclosure Control and Enclosure Status diagnostic pages provide access to the control and status
elements identified by the SCSI Enclosure Services (SES) standard. The Enclosure Control diagnostic page
is written using the SEND DIAGNOSTIC CDB. The Enclosure Status diagnostic page is read by sending a
RECEIVE DIAGNOSTIC RESULTS CDB with a page code valid (PCV) bit set to one and a PAGE CODE field
set to 02h.
4.4.1
Overview of Control/Status Element Handling
The SCSI Enclosure Processor (SEP) parses a control element instance only if SELECT bit is set. Reserved
bits are ignored in a control instance, overall or element, if the block SELECT bit is not set.
If the SELECT bit is set on an overall control element, that overall control element’s settings are used to
provide control for all of the elements with the type representing the overall control element. If an individual
instance’s element control block has its SELECT bit set, the settings in the individual instance element
control block take precedence over the settings in the overall control element block.
The SEP forms overall status element blocks by combining the status fields of each of the underlying
element instance blocks for all of the elements of the type that the overall status element represents.
This process is referred to as status field promotion, and is subject to the following rules:
• Status fields in which bits are promoted using logical OR, the overall status element block will contain a
set bit if any of the underlying element instance blocks have that bit set (for example, IDENTIFY, FAIL,
prdFail, OFF, and so on).
• Status fields which are measured readings are not promoted to the overall status element
corresponding to those values are set to all zeroes in the overall status element block (for example,
temperature readings, voltage readings, fan RPMs, fan speed codes, and so on).
•
The ELEMENT STATUS CODE field is promoted by copying the worst case value of the reported
ELEMENT STATUS CODE of any of the underlying element instance blocks. The following list displays
the priority order of ELEMENT STATUS code values, from highest to lowest. The following list also
serves to document the entire set of supported values of the ELEMENT STATUS CODE field, and their
meanings:
◦
No Access Allowed (8h)
■ SEP has placed this component into a state where it is not accessible to the host. An example
of this is a drive that has been taken offline due to a thermal fault.
◦
Unknown (6h)
■ SEP had an internal BIST failure or cannot communicate with the element instance to
ascertain its status due to a communication failure, for example, if the I2C bus is down.
◦
Unrecoverable (4h)
26
SES

■ SEP is reporting a condition which is unrecoverable and requires manual intervention. An
example of this is the presence of an unsupported drive type or a thermal fault that has
resulted in a transition to low power state.
◦
Critical (2h)
■ SEP is reporting a failure condition, or a sensor reading that exceeded the over or under
critical threshold.
◦
Noncritical (3h)
■ SEP is reporting a warning condition, a predicted failure, or a sensor reading that exceeded
the over or under warning threshold.
◦
Not Installed (5h)
■ The element instance is not installed.
◦ Not Available (7h)
■ The element instance is installed, but status information is not available for a reason that does
not indicate a communication failure. An example of this is if a drive is powered down and
therefore its temperature sensor cannot be read, or a drive temperature sensor has not yet
been polled to ascertain its reading.
◦ OK (1h)
■ None of the aforementioned conditions are present.
The SEP sets the Enclosure Status page header status bits to summarize the status conditions of any
element instance reported by the page. The following displays status conditions of element instances:
•
INVOP
◦ This bit is never set
• INFO
◦ This bit is always set
•
NON CRIT
◦ This bit is set to indicate that one or more element instances has an Element Status Code value of
Noncritical (3h)
•
CRIT
◦ This bit is set to indicate that one or more element instances has an Element Status Code value of
Critical (2h)
•
UNRECOV
◦ This bit is set to indicate that one or more element instances has an Element Status Code of
Unrecoverable (4h) or Unknown (6h)

4.4.2
Overview of Visual Indicator Handling
The SCSI Enclosure Processor (SEP) provides users with visual indication of various conditions within
the enclosure. Visual indication is provided through light-emitting diodes (LED) which are located
nearby or inside components within the enclosure. Each visual indicator consists of a single LED, which
displays a flash pattern that is used to signal different types of conditions. Each LED flash pattern has a
corresponding priority associated with it. The priority is used to choose which flash pattern to display when
multiple conditions warranting a flash pattern are simultaneously present.
The following list displays the LED flash patterns supported by the SEP, from highest to lowest priority:
• LED on with Fault flash pattern duty cycle (0.5 second period, 50%)
• LED on with Identify flash pattern duty cycle (2 second period, 87.5%)
• LED on with 100% duty cycle
• LED off with 0% duty cycle
Visual indicators can be autonomously set and cleared in response to enclosure detected conditions,
or they may be set or cleared with the SES Enclosure Control page 02h. The following list displays the
ELEMENT STATUS CODE values lead to the display of a fault flash pattern:
• Unknown (6h)
• Unrecoverable (4h)
• Critical (2h)
• Noncritical (3h)
There are many cases in the enclosure design in which a single LED will serve as a shared visual indicator
for multiple child components. An example of this would be a visual indicator located in the Enclosure
Services Controller Electronics (ESCE). All of the SCSI Enclosure Services (SES) element instances located
within that ESCE share the same visual indicator (for example, SAS expanders, temperature, voltage,
and current sensors, and so on). If more than one condition for which a visual indication was required is
simultaneously present among the set of components sharing a visual indicator, only the highest priority
visual indication would be displayed on the visual indicator’s LED.
It is possible that more than one condition requiring visual indication is simultaneously present on
any single element instance. For example, the SEP could detect an over-temperature condition on a
temperature sensor, and the host could request Identify to help a service technician locate the faulty
temperature sensor. The SEP would operate only the Fault flash pattern on the temperature sensor’s visual
indicator until the Identify request was made, at which time, the visual indicator would change to displaying
the higher priority Identify flash pattern. If the Identify request was turned off by the host, the LED would
resume displaying the Fault flash pattern, assuming that the over-temperature fault condition was still
present.
4.4.3
Interaction of Visual Indicators and Host Initiated Identify/
Fault Requests
The SCSI Enclosure Services (SES) standard states that host SES Enclosure Control bits RQST IDENT
and RQST FAULT, control visual indications on the associated element instance. The SES Enclosure Status
page bits IDENT and FAULT indicate that a visual indication for the associated element instance, is active.
In accordance with the previously mentioned indication, the SEP ignores host requests to identify or fail
an element instance if the associated visual indicator is not physically present in the current enclosure
topology.

Each enclosure defined by the Data60 3000 Series architecture contains a factory default set of
thresholds for temperature, voltage, and current sensor components.
These thresholds may be overwritten to a more conservative set of user defined values by a host using the
Threshold Out page (for example, lowering the high warning/critical threshold or raising the low warning/
critical threshold, and so on). User defined thresholds override the factory default thresholds. User defined
changes to thresholds are volatile, and are only in effect until the next time the SCSI Enclosure Processor
(SEP) is power cycled or reset.
If a host attempts to establish thresholds which are less conservative than the factory defaults the SEP will
return a Check Condition status without changing any threshold parameters specified in that request (for
example, raising the high warning/critical thresholds or lowering the low warning/critical thresholds, and so
on).
The Threshold diagnostic page follows the same element instance layout as the Enclosure Control and
Enclosure Status diagnostic pages. For each element type, there is an overall entry followed by individual
entries for each instance.

The TICK COUNTER field is a 32 bit value that reports the number of seconds that the SCSI Enclosure
Processor (SEP) has been running.
The MONITOR LOOP COUNTER is a 32 bit value that indicates the number of iterations of the background
monitor loop.
The MONITOR LOOP RECENT LATENCY is a 32 bit value that indicates the latency in milliseconds of the
most recent invocation of the background monitor loop.
The IDLE LOOP MAXIMUM LATENCY is a 32 bit value that indicates the maximum latency in milliseconds of
any invocation of the background monitor loop since the most recent SEP boot.
The OFFLINE STATE REASON MASK field reports the reason(s) for the current offline state condition. The
following list displays bitmask values:
• 00000000h: enclosure is not offline
• 00000001h: unsupported drive configuration
• 00000002h: SEP is unable to read enclosure Vital Product Data (VPD)

• 00000004h: thermal fault condition
The POWER STATE field is a 32 bit value that indicates the power state of the enclosure. The values
reported range from 0, standby power only, to 3, full power. Values of 1 and 2 indicate intermediate states.
The PSU A AC FAILURE COUNTER and PSU B AC FAILURE COUNTER fields are 32 bit values that indicate
the number of times that the respective power supply detected a failure of the AC input voltage. These
counters are not reset to zero if a power supply is inserted or removed.
The PHY RESET – LAST ID and PHY RESET – EVENT COUNT fields are used to report cases where the
SEP autonomously resets a host, disc, or interconnect physical layer (PHY) because it negotiated to a
suboptimal link rate.
The PHY RESET – LAST ID field reports the ID of the last PHY to be reset, and the PHY RESET – EVENT
COUNT reports the total number of times any PHY has been reset in an attempt to improve a suboptimal
link rate.
The BIST FAILURE – EVENT COUNT field is a 32 bit value which reports the number of times that the
enclosure detected a built-in self-test (BIST) failure. The counter is volatile, and will reset to 0 when the
enclosure is reset of powers on.

Element Descriptor Page (07h)
The Element Descriptor Page can be returned in one of two formats, with or without Manufacturing/
Customer (MFC) data. MFC data is enabled by default. If no MFC data is required this feature can be
disabled at manufacturing resulting in the shorter page length. The MFC data is ASCII printable data with
unused portions filled with ASCII spaces (20h). The MFC data is intended to contain information necessary
for inventory tracking but may contain any ASCII data determined by manufacturing and/or customers.
These fields are settable only during manufacturing. See individual Element Descriptor Format sections for
details.
4.7.1
Element Descriptor
The Element Descriptor page contains ASCII byte arrays which report information about the enclosure
instances. The ASCII fields in the Element Descriptor page are not NULL terminated. The element
descriptor page contains information about SES defined element type instances as well as other CRU
types not directly modeled by SES such as the drives. The exact information provided for each element
includes the following types of data:
• Location (indicates parent CRU)
• Part Number
• Serial Number
• Firmware Revision
The Element Descriptor diagnostic page follows the same element instance layout as the Enclosure
Control and Enclosure Status diagnostic pages. For each element type, there is an overall entry followed by
individual entries for each instance.

The Download Microcode diagnostic page is used to transmit a firmware image to the enclosure services
process.
The PAGE LENGTH field indicates the number of bytes in the header block and data bytes.
The MODE field is set to the value 0Eh to indicate that a segment of firmware is being downloaded to the
SCSI Enclosure Processor (SEP). The length of the entire firmware image is in FIRMWARE IMAGE LENGTH.
The data associated with the current segment of firmware being downloaded is located in FIRMWARE
PACKET DATA, the length of the current segment is in FIRMWARE PACKET LENGTH, and the offset of the
segment is in BUFFER OFFSET. The host must send the individual segments in order of increasing BUFFER
OFFSET.
The MODE field is set to the value 0Fh to pass notification to the SEP to begin using the new firmware
image data sent by previous commands with the MODE field set to 0Eh. When the MODE field is set to 0Fh,
FIRMWARE PACKET LENGTH is expected to be 00h.

The BUFFER ID field must always be set to 00h. The SEP code update process automatically detects the
firmware components provided in the data phase and distributes the new images to the expanders, power
supply, and so on. Drives are not updated via this mechanism. In the case of SEP code update, the enclosure
automatically distributes the received code image to all expanders in the enclosure.

Tag Data Out/In Diagnostic Page (10h)
The Tag Data diagnostic page is a vendor unique SCSI Enclosure Services (SES) diagnostic page that
provides the host with access to a 4096 byte tag data buffer. The tag data buffer is non-volatile, and is
stored in Enclosure vital product data (VPD).

SES Reference
4. SES Diagnostic Pages
4.13 MiniSAS HD Cable VPD Diagnostic Page (17h)
This buffer can be written with arbitrary American Standard Code for Information Interchange (ASCII) or
hexadecimal (HEX) data. Each write to the tag data buffer, regardless of the size written, replaces the entire
contents of the tag data buffer. Writing 0 bytes, PAGE LENGTH = 3, will clear the tag data buffer.
On reads, the PAGE LENGTH will indicate the length of the tag data which has actually been stored in the
enclosure. In other words, reading the tag data buffer returns an amount of data equal to the length of the
last write to the tag data buffer, rather than the maximum size of the Tag Data region.

When the host sets a nonCrit, Crit, or unRecov bit using control page 2, the bit is marked as
FAULT_REQUESTER_SES. When the page 3 builder runs, it displays a result of "HOST" for these entries in
the page 2 header. If marked for any other reason, it will display "SES" as seen in the following example:
|Enclosure Overall Status|
NON-CRIT=1 (SES)
CRIT=1 (HOST)
There are statuses that help indicate what sets the bits on individual elements. They are displayed by the
page 3 builder and include:

SES set by host via page 2 control
THRESHOLD set by voltage, current or temperature threshold exceptions
SES GEN set by SES generic update on critical or non-critical state

Note: RQST IDENT, PRDFAIL, DEVICE OFF, and RQST FAULT are considered persistent for
Array device fields. When these fields are set through a control request page 2, they will retain
their state through enclosure resets and drive replacements. To clear these fields when set
by page 2, another page 2 must be sent with the desired field cleared. If these fields are
set without control page 2, then they will not be persistent and will clear on reset or drive

The DEVICE OFF bit is used to power a drive off. The drive power-off operation will complete
asynchronously with respect to host initiated I/O operations to that drive or others in the array. Due to
limitations, some drive types supported by the Data60 3000 Series architecture contain a finite maximum
number of power cycles. The SCSI Enclosure Processor (SEP) will reject a DEVICE OFF request until a
minimum relaxation time has elapsed since the last DEVICE OFF request for that Array Device slot. This will
only occur if a large number of DEVICE OFF requests have been performed on that slot in the lifetime of
the drive. Should this occur, the host will be given a Check Condition with sense data indicating which Array
Device Slot Element instance requires this relaxation time.
During thermal shutdown conditions, the SEP will reject external host commands to control drive power.
Once the SEP has exited thermal shutdown state, drive power states will be automatically returned to their
prior states and future host requests to control drive power will be honored.

The ELEMENT STATUS CODE has a value of CRITICAL to indicate that the corresponding Array Device
Slot is unable to communicate because the interconnect physical layer (PHY) has not achieved a link up
state.
The ELEMENT STATUS CODE has a value of NON-CRITICAL to indicate that the corresponding Array
Device Slot is able to communicate, but the interconnect PHY is operating at a non-optimal link rate.
The DEVICE OFF bit is true if the corresponding drive is powered off. A drive can be powered off in
response to a host sending a SES Page 2 control page, or if the enclosure autonomously powers a drive off
during a thermal offline state.

The FAILURE INDICATION and WARNING INDICATION bits are only set to indicate failure and warning
conditions which are requested by hosts by sending an Enclosure Element Control block. The WARNING
INDICATION bit is set to 1 to indicate that either the PRDFAIL or the WARNING REQUESTED bits in the
Enclosure Element Control block was set.
The FAILURE INDICATION and WARNING INDICATION bits do not serve as failure and warning summary

discovered by using the Threshold In Diagnostic page.
Temperature sensors which are located on drives are polled less often than temperature sensors located

The TEST UNIT READY command requests that the device server indicates if the logical unit is ready. If the
SEP is able to accept SES page commands without returning CHECK CONDITION status, then the SEP shall
complete the command with a GOOD status. If the SEP is nonoperational, the device server shall terminate
the command with a CHECK CONDITION status, with the sense key set to NOT READY.

6.3 Request Sense
Note: The Data60 3000 Series SEP can enter an offline state in which SEP remains available,
but the disk drives are not presented to hosts. Because the SEP remains available, the SEP will
return a SCSI GOOD status in response to TEST UNIT READY even if it is in offline state.

Request Sense
The REQUEST SENSE command requests that the SEP return sense data in the data phase of the
operation. It is seldom used because SAS provides auto-sense in the response frame following the
completion of each SCSI command.

EVPD bit set to 0 specifies that the logical unit shall return the standard INQUIRY data. If the PAGE CODE
field is not set to 0 and the EVPD bit is set to 0, then the command will terminate with CHECK CONDITION
status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to INVALID
FIELD IN CDB. If the EVPD bit is set to 1, the PAGE CODE field specifies which page of vital product data
information the logical unit shall return. If the page code is not implemented by the logical unit the command
will terminate with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the
additional sense code set to INVALID FIELD IN CDB.

The Device Identification VPD page provides the means to retrieve designation descriptors applying to
the logical unit; SEP. The SEP reports four designation descriptors. Designators will consist of one of each
of the following:
• Target port designator
• Logical unit designator
• Target device designator
• Relative target port designator
Note: Application clients should use the designation descriptors during system configuration
activities to determine whether or not multiple paths exist to communicate with the same
peripheral device.
