3.2.2.6 Display Information of SES Devices
The
SES SHOWDEVICES
command displays all the SES devices on all channels.
The SES SHOWALL command displays all configuration information for all the SES devices on all
channels.
The SES SHOW=<tier><channel> command displays the configuration information and the status
information returned from an SES Enclosure Status page for the SES device for the specified drive
in the range of <1..125><ABCDEFGHPS>.
3.2.2.7 Visual Indication of Drive
The SES IDDISK=<tier><channel> command provides a visual indication of the specified drive,
<1..125><ABCDEFGHPS>. The status LED of the drive blinks until the command SES ID=OFF is
issued, which restores the system to its original visual state.
3.2.2.8 Visual Indication of Tier
The SES IDTIER=<tier> command provides a visual indication of the specified tier, <1..125>. The
status LED of the drives blinks until the command SES ID=OFF is issued, which restores the system
to its original visual state.
3.2.2.9 Visual Indication of Channel
The SES IDCHANNEL=<channel> command provides a visual indication of the specified channel,
<ABCDEFGHPS>. The status LED of the drives blinks until the command SES ID=OFF is issued,
which restores the system to its original visual state.
3.2.2.10 Visual Indication of LUN
The SES IDLUN=<LUN number> command will provide a visual indication of the specified LUN,
<0..127>. The status LED of the drives will blink until the command SES ID=OFF is issued, which will
restore the system to its original visual state.
3.2.2.11 Verify Connections to Drive Enclosures
There are two commands to verify connections to the drive enclosures:
• Use the SES VERIFY_6016 command to verify the connections of an SF6016 drive enclosure that
is currently attached to the system. The connections must be verified before the SCSI Enclosure
Services (SES) can accurately indicate a drive fault through SES commands.
• Use the
SES VERIFY_6012REM
command to verify the connections of an SF6012REM drive
enclosure that is currently attached to the system. The connections must be verified before the
SCSI Enclosure Services (SES) can accurately indicate a drive fault through SES commands.
Use the SES RESET_VERIFIED_ENCLOSURES command to remove all of the verified drive
enclosures from the verified enclosures list for this S2A9550 unit.
3.2.3 Tier Mapping for Enclosures
The S2A supports various drive enclosures. When the system is first configured, it is necessary to
select a tier mapping mode so that the position of the tiers in the system are changed to conform with
the layout of your drive enclosures. The tier mapping information also allows the S2A9550 to
properly light the enclosure fault LEDs.
