27 ATTO Technology Inc. ATTO Utilities Installation and Operation Manual
Using SCSI Enclosure Services (SES)
SAS/SATA drive enclosures may provide a SCSI Enclosure Processor which indicates enclosure health status,
drive identification and drive fault identification.
The ATTO ConfigTool recognizes drive enclosures
that provide SCSI Enclosure Services (SES). You may
use SES to identify individual drives, all the drives in
the same enclosure, all the drives in a single RAID
group, or faulted drives. You may also select drives
and monitor the status of the enclosure.
To use SES, open the ATTO ConfigTool and follow one
of the procedures below.
Identifying Drives
Drive Identification lights LEDs showing the drives
you have selected using the ATTO ConfigTool. Most
drive enclosures blink an LED next to the drive in the
enclosure.
The ConfigTool provides a way to identify individually
selected drives, all of the drives in the same enclosure,
all drives in a RAID group, a selected mirror group in
RAID 1 or RAID 10, and faulted drives.
Note
Drive Identification works for drives that are
not controlled by a SCSI Enclosure Service.
The ATTO ConfigTool provides functionality
to locate all or specifically selected drives in
a RAID group, when a SES processor is not
present.
1 Select one or more drives individually or in
enclosures or drives in RAID groups:
• Select individual drives in the Attached
Drives panel.
• Select one or more RAID groups in the
Groups panel.
• Select one or more drives in the Attached
Drives panel, right click on one of the
selected drives and select Enclosure.
2 Right-click on one of the selected drives or
RAID groups.
3Select Locate.
Note
If a RAID 1 or RAID 10 group was selected,
the locate operation provides the capability
to select a specific mirror of the group.
The status icon next to the selected drives
blinks and the enclosure performs its specific
identification method until you stop it.
4 To stop the drive identification, right-click on
one of the selected drives or RAID groups.
5 De-select Locate.
Identify Faulted Drives
Drive Fault Identification is performed automatically
by the ExpressSAS RAID or ThunderStream SC
storage controller when a member of a RAID group
becomes degraded by exhibiting unrecoverable errors
during I/O.
The ExpressSAS RAID or ThunderStream SC storage
controller reports the status of the drive and asks the
SES device to perform fault identification. The SES
device usually illuminates a blinking red LED as a fault
identification.
The fault identification continues until the drive is
replaced or the RAID group is deleted.
Selecting All Drives in the Same Enclosure
Drive Selection selects all drives in the same
enclosure using the ConfigTool. You may use drive
selection if you need to select all the drives in one
enclosure which are attached to a RAID storage
controller without selecting other enclosures, or if you
are selecting members for a RAID group during RAID
group creation.
1 Right click on one drive in the Attached Drives
panel.
2Select Enclosure.
3Select Drives. All drives in the same enclosure
as the selected drive are selected.
