304 Managing the Disk Array Using Array Manager 60
Performing Disk Array Maintenance
At some point during operation of the disk array, you may need to perform maintenance
tasks that involve error recovery and problem isolation. This section describes the tasks
involved in maintaining the disk array.
Locating Disk Modules
Array Manager 60 provides the means of identifying a disk module by flashing its amber
Fault LED. You can flash the Fault LED on an individual disk, or on all the disks in the
array. It is advisable to positively identify a failed disk before removing it from the disk
array. Removing the wrong disk could cause the data on the LUN to become unavailable.
To locate a disk module, type:
amutil <option> <ArrayID>
• option identifies the disk modules you want to identify. Table 39 lists valid options.
Command Example
The following example flashes the Fault LED on disk 3 on channel 2 in disk array
data_center_1:
amutil -f 2:3 data_center_1
Table 39 Command Options for Locating Disk Array Components
Option Description
-f channel:ID Flash the Fault LED on the specified disk. A disk is identified by both
channel (1- 6) and SCSI ID (0 - 4, 8 - 12).
-F Flash the Fault LEDs on all the disks in the disk array.
-s Stop flashing the disk Fault LEDs. This option works for both a single
disk and multiple disks.
