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.
IMPORTANT:
Before removing a failed controller, always verify that the amber fault LED
is lit and that the controller does not display a blinking activity LED.
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 uses 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 to the system.
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.
