Identifying Failed Drives
If a failed drive is in an enclosure that supports SES
(SCSI Enclosure Services), the drive's Fault LED
should be blinking. In that case, it is clear which drive
should be replaced. If multiple drives are blinking,
power cycling the array and/or the drives, and
reseating the drives can sometimes correct
intermittent conditions.
ATTO supplies other facilities to aid in failed drive
identification. When there is some question about
which drive has failed, use either the CLI command-
line interface or the ATTO ConfigTool procedures
described below to be very sure as to which drive
failed, prior to replacing the drive.
Using ATTO ConfigTool to Identify a
Failed Drive
The ATTO ConfigTool provides a graphical display of
RAID Groups and attached drives.
Exhibit 1.5.1--18 ,
below, shows a RAID Group with a status of
DEGRADED. The upper window shows attached
disks and their association with RAID Groups.
