If the state of the logical drive is critical you must replace
and rebuild the defunct drive. See “Rebuilding a defunct
drive” on page 157 for more information.
Physical drive state descriptions:
The following table provides descriptions of the valid
physical 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 157 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).
