Table 21. Status of volume (continued)
Status of volume Description
Rebuilding (RBLD)
or Resyncing (RSY) A data resynchronization or rebuild might be in progress.
Inactive, Okay
(OKY) The volume is inactive and the drives are functioning correctly. The
user data is protected if the current RAID level is RAID 1 (IM) or
RAID 1E (IME).
Inactive, Degraded
(DGD) The volume is inactive and the user data is not fully protected due
to a configuration change or drive failure; a data resync or rebuild
might be in progress.
5. Review the section for Drive information and the value for State Figure 7 on
page 59, then see Table 22 to see the possible values for State of the drives.
Table 22. State of drives
Status of drives Description
Online (ONL) The drive is operational and is part of a logical drive.
Hot Spare (HSP) The drive is a hot spare that is available for replacing a failed drive
in an array.
Ready (RDY) The drive is ready for use as a normal disk drive; or it is available to
be assigned to a disk array or hot spare pool.
Available (AVL) The drive might or might not be ready, and it is not suitable for
inclusion in an array or hot spare pool (for example, it did not spin
up, its block size is incorrect, or its media is removable).
Failed (FLD) The drive was part of a logical drive or was a hot spare drive, and it
has failed. It has been taken offline.
Standby (SBY) This status is used to tag all non-hard disk drive devices.
Missing (MIS) The hard drive might be removed.
Out of Sync (OSY) A data resynchronization or rebuild might be in progress.
6. See Figure 8 on page 61 for an example that shows that mirroring is
re-synchronizing. If a hard disk drive is removed and reinserted, the array
starts to resynchronize automatically.
Notelist: You can tell that the mirroring is re-synchronizing when the following
conditions are true:
v
State of volume is Resyncing (RSY)
v
Current operation is Synchronize
v
Percentage complete is displayed
A mirror/volume consists of two hard drives. In Figure 8 on page 61, the
section for
Mirror Information hs a status line called Physical hard disk
(Target ID) . The line shows which drives are part of the mirror/volume.
The Status of volume shows Resynching (RSY) .
The mirror consists of
Physical hard disk (Target ID)
of
6
and
9
. Drive 9 is in a
State
of
Out of Sync (OSY)
. The
Mirror Information
will also show you the
percentage complete for the resynchronization. For example, the percentage
complete in Figure 8 on page 61 is
5.23% .
