Logical Drive State Descriptions


Logical Drive State Descriptions

The following table provides descriptions of the valid logical drive states.

If the state of the logical drive is critical you must replace and rebuild the defunct drive. See 'Rebuilding a Defunct Drive' for more information.
Drive State    Meaning
   Blocked    During a rebuild operation, the ServeRAID controller sets the
     state of any RAID level-0 logical drives associated with a
     failed array to the Blocked state, then, it reconstructs the
     data that was stored in RAID level-1 and RAID level-5 logical
     drives.
     After the Rebuild operation completes, you can unblock the
     RAID level-0 logical drives, and access them once again.
     However, the logical drive might contain damaged data.
     You must either re-create, install, or restore the data from the
     most recent backup disk or tape to the RAID level-0 logical drive.
   Critical    A logical drive in the critical state that is undergoing a logical
   Migrating    drive migration (LDM).
   Critical    The ServeRAID controller uses this reserved state during a logical
   System    drive migration (LDM).
   Critical    A RAID level-1 or level-5 logical drive that contains a defunct
     physical drive is in the critical state. A critical logical drive
     is accessible, despite a physical drive failure.
     Attention
     If the state of the logical drive is critical,replace and rebuild
     the defunct drive as soon as possible to prevent the loss of data.
     If a second drive fails before the first rebuild completes, you
     might lose valuable data.
     See 'Rebuilding a Defunct Drive' for more information.
   Migrating    The logical drive is undergoing a logical drive migration, that is,
     a change in RAID levels, a change in logical drive size, or an
     increase in free space.
   Offline    The logical drive is offline and not accessible. This state occurs if
     one or more physical drives in a RAID level-0 logical drive is defunct.
     This state also occurs when two or more physical drives in a RAID
     level-1 or level-5 logical drive are defunct.
   Okay    The logical drive is okay. It is in a good, functional state.
   System    The ServeRAID controller uses this reserved state during logical drive
     migration (LDM).


If the state of the logical drive is critical you must replace and rebuild the defunct drive. See 'Rebuilding a Defunct Drive' for more information.
