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.
