1201 A solid state drive requires a recovery.

Explanation

The solid state drive identified by this error has suffered an error which requires the drive to be reformatted before it can be used again. A corruption in the drive metadata has caused all of the data on the drive to be lost. The drive is still usable, but it must be reformatted to resolve the issue.

Action

The following actions delete all the VDisks and VDisk host maps for the managed disk group that contains the offline managed disk. Therefore, it is strongly recommended that you back up the SVC configuration with the svcconfig backup command so that you can use the backup file later.

If the MDisk is a managed mode MDisk:

  1. Record all of the properties of all of the VDisk copies, including unmirrored VDisks, that use storage from the managed disk group that contains the offline managed disk. Record all of the properties of the managed disk group and the list of all of the managed disks in that managed disk group.
  2. Delete the MDisk group that contains the affected MDisk. The affected MDisk will become unmanaged and have a state of Offline.
  3. Submit the command 'svctask includemdisk (mdisk)', where (mdisk) is the name or the ID of the offline MDisk.
  4. Create a new managed disk group with the same properties as the deleted managed disk group and add the drive back into the managed disk group.
  5. Adding the disk into the managed disk group in step 4 reformats the drive. The reformat process might take some time to complete. Warning: Do not remove the solid state drive from the node while the disk is being formatted.
  6. If the reformat process does not complete within 3 minutes the command will fail with the message 'CMMVC6297E One or more managed disks (MDisks) have timed out during validation tests. The first failing MDisk ID is (managed disk ID)'. In this case, resubmit the 'svctask addmdisk (mdisk)' command until the MDisk is successfully added to the managed disk group.
  7. Add all of the other managed disks that were in the deleted managed disk group into the new managed disk group.
  8. Add a VDisk copy for all of the VDisks that were mirrored in the original managed disk group.
  9. Create all of the standard VDisks that were members of the original managed disk group and restore data from backups using the information recorded in step 1.

If the MDisk is an image mode MDisk:

  1. Record the properties the image mode VDisk.
  2. Delete the image mode VDisk for the affected MDisk. The MDisk will become unmanaged and have a state of Offline.
  3. Submit the command 'svctask includemdisk (mdisk)', where (mdisk) is the name or the ID of the offline MDisk.
  4. Create a new, temporary, managed disk group and add the MDisk into this new managed disk group.
  5. Adding the disk into the managed disk group in step 4 reformats the drive. The reformat process might take some time to complete. Warning: Do not remove the solid state drive from the node while the disk is being formatted.
  6. If the reformat process does not complete within 3 minutes the command will fail with the message 'CMMVC6297E One or more managed disks (MDisks) have timed out during validation tests. The first failing MDisk ID is (managed disk ID)'. In this case, resubmit the 'svctask addmdisk (mdisk)' command until the MDisk is successfully added to the managed disk group.
  7. Delete the temporary managed disk group that was created in step 4.
  8. Either recreate the image mode VDisk or add the image mode VDisk copy, depending on the original configuration of the VDisk.
