Replacing a Failed Controller in a Redundant
Controller Environment
A failed controller can be replaced without powering down the shared storage
array. To replace a failed controller:
1.
Remove the failed controller.
2.
Insert the new controller.
Replacing a Failed Drive
A failed drive can be replaced without powering down the shared storage
array. When a drive fails, two things can happen:
■
The logical drive associated with the failed drive utilizes a spare and
rebuilds the spare drive to join the logical drive. The logical drive will
be in a reconstructing state.
■
The logical drive stays in a reduced state until a new drive is added.
To replace the failed drive:
1.
Remove the failed drive.
2.
Insert the new drive.
3.
See the “Adding Physical Drives” section for procedures to make the
new drive known.
4.
Set the new drive status.
If a spare drive was used to reconstruct the affected logical drive, set the
new drive as a spare drive.
If there was no spare drive to use, the logical drive is still in a reduced
state. Add the new physical drive to the logical drive and reconstruction
can start.
a.
Select the logical drive in reduced status.
b.
Select Logical Drive from the Storage pull down menu.
c.
Select Reconstruct.
d.
A list appears showing you available drives. Select the drive you just
added.
e.
Reconstruction begins.
