Goal

Replacing a Disk in the Common Array Manager (CAM)

Fix

DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE ENGINEER/ADMINISTRATOR NEED:
Disk Drive Replacements are very common and are covered in great detail in
the Common Array Manager.

***ATTENTION***
If you are replacing a disk that is one of these drive models:

ST330055SSUN300G
ST330055FSUN300G

AND the controller Firmware of the array is 7.x but not:

*6x40 Array 7.60.53.10 or later
*6x80 Array 7.60.53.10 or later
*FLX380 Array 7.60.53.10 or later
*25x0 Array 7.35.55.11 or later

please consult <DOCUMENT 1300555.1> to avoid a potential outage.

TIME ESTIMATE: 15 minutes

ENGINEER/ADMINISTRATOR INSTRUCTIONS
PROBLEM OVERVIEW:
Disk drive has been determined as failed by the system

WHAT ACTION DOES THE ENGINEER/ADMINISTRATOR NEED TO TAKE:
1. Verify drive assignment. If a HOT SPARE, have the ADMINISTRATOR will need to UNASSIGN it before proceeding. Failure to do so may result in an alarm of "Missing Hot Spare Drive". Please consult <DOCUMENT 1450121.1> if this occurs.
2. Use the Service Advisor(SA) for the Array in question to review drive replacement directions. This will also instruct you on how
to toggle the drive location indicator for replacement. Use the indicator to locate the drive in question. The drive should also
be failed/faulted in the SA, Unless it is UNASSIGNED. If an assigned drive is not failed, contact the TSC or verify the reason for the drive replacement yourself.
NOTE: DO NOT FAIL AN UNASSIGNED DRIVE!!!
3. The drive location specified should be indicated by an amber fault LED for that Tray and Slot, as well as the white location LED
if available on that tray.
4. Remove the drive, and verify that the drive is the same:
a) type: SAS/SATA/FC/SSD
b) size
c) RPM
NOTE: the drive make and model do not have to be the same, only the type, size and RPM.
5. Replace the drive according to the instructions in the SA.
NOTE: If the drive firmware needs updating, the customer will have to schedule this at a later date, as a copy back is typically immediate.
OBTAIN ADMINISTRATOR ACCEPTANCE
WHAT ACTION DOES THE ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
1. Verify with that the drive is in an OK or Optimal state.
2. Verify with that the Virtual Disk(VDisk) is reconstructing (if RAID 1,3,5,6). If it is not, you may need to manually start the reconstruction. See Reference Section.
3. Verify that all Alarms regarding drives bypassed, degraded drive channel, and impending failures have been removed from the system.
4. If the VDisk is a RAID 0, the volumes on the Vdisk will need to be deleted, or initialize the VDisk.

Initialize RAID 0 VDISK:
1. Revive the drive you just inserted through the UI or Service Advisor
2. Initialize the VDisk using the service command:

service -d <array_name> -c initialize -t <vdisk_name>

You will need to supply the Service password in order to complete this task.

The service command can be found in the following locations:

Solaris: /opt/SUNWsefms/bin/service

Windows: \Program Files\Sun\Common Array Manager\Component\fms\bin\service.bat

Linux: /opt/sun/cam/private/fms/bin/service

Example:

# ./service -d my_array -c initialize -t my_vdisk

Executing the initialize command on my_array



WARNING: Executing this command will irretrievably delete all data from this virtual disk's volumes!



Are you sure? (y/n) y

Enter the array password: array_password

Formatting Test_Volume

Completion Status: Success

#

This option was not available in the earliest versions of CAM. If this command fails, then the volumes must be deleted.

PARTS NOTE:

NOTE: If the service advisor is not available, you may download or review a soft copy internally at:
