Error in RAID Disk Setup on a PA-7050

Issue

If there is an error in the disk setup, running the show system raid detail command will show the following message:

> show system raid detail

Disk id A1 Present

size : 953869 MB

status : failed

Resolution

1. Run the CLI commands to prepare for the removal of disk pair A
   > request system raid slot s8 remove A1
   > request system raid slot s8 remove A2
   Note: The above commands are executable so that the two disks can be swapped.
2. Swap drives physically.
3. Run the CLI commands to add the drives to the system:
   > request system raid slot s8 add A1 force no-format
   > request system raid slot s8 add A2 force no-format
4. Track progress with the less s8lp-log raid.log command
   For example:
   > less s8lp-log raid.log
   s8lp\raid.log                      02-20 11:32:17   DEBUG: Rebuild of Disk Pair S8A Partition 1 40 percent complete.
   s8lp\raid.log                      02-20 12:08:49   DEBUG: raid_util: argv: ['Rebuild60', '/dev/md1']
   s8lp\raid.log                      02-20 12:08:49   DEBUG: Rebuild of Disk Pair S8A Partition 1 60 percent complete.
   s8lp\raid.log                      02-20 12:50:22   DEBUG: raid_util: argv: ['Rebuild80', '/dev/md1']
   s8lp\raid.log                      02-20 12:50:22   DEBUG: Rebuild of Disk Pair S8A Partition 1 80 percent complete.
5. Once the process is completed run the show system raid detail command to validate the status.
   For example:

> show system raid detail

Disk Pair S8A                         Available

   Status                                 clean

   Disk id A1                           Present

       model        : ST91000640NS

       size         : 953869 MB

       status       :  active sync

       card serial  : 002901000204

   Disk id A2                           Present

       model        : ST91000640NS

       size         : 953869 MB

       status       : active sync

       card serial  : 002901000209

Disk Pair S8B                         Available

   Status                                 clean

   Disk id B1                           Present

       model        : ST91000640NS

       size         : 953869 MB

       status       : active sync

       card serial  : 002901000205

   Disk id B2                           Present

       model        : ST91000640NS

       size         : 953869 MB

       status       : active sync

       card serial  : 002901000203

Disk formatting is not performed on disks already known to a System-DiskPair. If the disks are somehow juggled during a Log Processing Card (LPC) replacement, follow the steps below to resolve the raid status. The assumption is that the system's Disk Pair A is "Available" and disk A1 (SN x363) status is "active, sync".

1. For disk A2
   1. Run the following command:
      > request system raid slot s8 remove A2
   2. Physically eject the disk and insert into slot B1
   3. "Add" the disk in slot B1 using CLI (with "force" option)
      > request system raid slot s8 add B1 force
      Note: This will format the drive and take 3-4 minutes. Disk Pair B should become "Available".
2. For disk A1
   1. Run the following command:
      > request system raid slot s8 remove A1
   2. Physically eject the disk and insert into slot B2
   3. "Add" the disk in slot B2 using the following CLI command:
      > request system raid slot s8 add B2 force
      Note: This will start Raid mirroring to disk in slot B2
3. For old disk B2
   1. Physically insert it into slot A1
   2. Add the disk using the following CLI command:
      > request system raid slot s8 add A1 force
      Note: This will format the drive and take 3-4 minutes. Disk Pair A should become "Available".
4. For old disk B1
   1. Physically insert it into slot A2
   2. Add the disk using the following CLI command:
      > request system raid slot s8 add A2 force
      This will start Raid mirroring to disk in slot A2.

If there were logging issues to the disk pair, logging should start after 'Step a' (or 'Step c' if disk failures).

Check the output of show system raid detail for any disk status as "failed".
