Replacing, moving, or adding hard drives 23

CAUTION: If the Online/Activity LED on the replacement drive does not light up while the

corresponding LEDs on other drives in the array are active, the rebuild process has abnormally

terminated. The amber Fault LED of one or more drives might also be illuminated. Refer to

"Abnormal termination of a rebuild (on page 23)" to determine what action you must take.

Abnormal termination of a rebuild

If the Online/Activity LED on the replacement drive permanently ceases to be illuminated even while other

drives in the array are active, the rebuild process has abnormally terminated. The following table

indicates the three possible causes of abnormal termination of a rebuild.

Observation Cause of rebuild termination

None of the drives in the array have

an illuminated amber Fault LED.

One of the drives in the array has

experienced an uncorrectable read error.

The replacement drive has an

illuminated amber Fault LED.

The replacement drive has failed.

One of the other drives in the array

has an illuminated amber Fault LED.

The drive with the illuminated Fault LED has

now failed.

Each of these situations requires a different remedial action.

Case 1: An uncorrectable read error has occurred.

1. Back up as much data as possible from the logical drive.

CAUTION: Do not remove the drive that has the media error. Doing so causes the logical drive

to fail.

2. Restore data from backup. Writing data to the location of the unreadable sector often eliminates the

error.

3. Remove and reinsert the replacement drive. This action restarts the rebuild process.

If the rebuild process still terminates abnormally:

1. Delete and recreate the logical drive.

2. Restore data from backup.

Case 2: The replacement drive has failed.

Verify that the replacement drive is of the correct capacity and is a supported model. If these factors are

not the cause of the problem, use a different drive as the replacement.

Case 3: Another drive in the array has failed.

A drive that has recently failed can sometimes be made temporarily operational again by cycling the

server power.

1. Power down the server.

2. Remove the replacement physical drive (the one undergoing a rebuild), and reinstall the drive that it

is replacing.

3. Power up the server.

If the newly failed drive seems to be operational again:

1. Back up any unsaved data.
