Vdisk Or Disk Group Member Unavailable - HP MSA 2040 Troubleshooting Manual

Table 11 RAID-6 reconstruction scenarios
Symptom
No compatible spares are available,
reconstruction does not start
automatically
One disk fails and a compatible spare is
available
Two disks fail and only one compatible
spare is available
Two disks fail and two compatible spares
are available

Symptom
Fault/UID LED illuminates amber
Online/Activity LED illuminates green
NOTE: Depending on the Vdisk or disk group RAID level and size, disk speed, utility priority,
and other processes running on the storage system, reconstruction can take hours or days to
complete. You can stop reconstruction only by deleting the Vdisk or disk group.

Action Required
To start reconstruction manually, replace each failed disk, and then do
one of the following:
Add each new disk as either a dedicated spare or a global spare.
Remember that a different critical Vdisk or disk group might take the
global spare than the one you intended. When a global spare replaces
a disk in a Vdisk or disk group, the global spare's icon in the enclosure
view changes to match the other disks in that Vdisk or disk group.
Enable the Dynamic Spare Capability option to use the new disks
without designating them as spares.
The system uses the spare to reconstruct the Vdisk or disk group. If a
second disk fails during reconstruction, reconstruction continues until it is
complete, regardless of whether a second spare is available. If the spare
fails during reconstruction, reconstruction stops.
The system waits five minutes for a second spare to become available.
After five minutes, the system uses the spare to reconstruct one disk in
the Vdisk or disk group (referred to as fail 2, fix 1 mode). If the spare fails
during reconstruction, reconstruction stops.
The system uses both spares to reconstruct the Vdisk or disk group. If
one of the spares fails during reconstruction, reconstruction proceeds in
fail 2, fix 1 mode. If the second spare fails during reconstruction,
reconstruction stops.
Symptom
Vdisk or disk group status is
OFFL (Offline).
Vdisk or disk group status is
OFFL (Offline).
Vdisk or disk group status is CRIT
(Critical).
Vdisk or disk group status is
FTDN (Degraded).
Cause
A disk fails.
A spare is used as a reconstruction target.
Action Required
A single drive failure causes the Vdisk or disk group to
go OFFL and Trust cannot recover the data. Data is
restored from the backup.
If a spare is already available (global or dedicated to the
Vdisk or disk group), it is used for the Vdisk or disk group
in CRIT or FTDN state and reconstruct begins. Replace
the failed disk drive if necessary. If a spare is not available,
consider the option to replace the failed disk drive or clear
meta-data on LEFTOVR drive and add it as a spare.
