Drive States
This section provides descriptions of the logical and physical drive
states.
Logical Drive State Descriptions: The following table provides
descriptions of the valid logical drive states.
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 Migrating
A logical drive in the critical state that is
undergoing a logical drive migration (LDM).
Critical System
The ServeRAID controller uses this reserved
state during a logical 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” on page 159 for
more information.
