Replacing, moving, or adding hard drives 31

4. After you have replaced the failed drives, fault tolerance may again be

compromised. If so, cycle the power again. If the 1779 POST message is

displayed:

a. Press the F2 key to re-enable the logical drives.

b. Recreate the partitions.

c. Restore all data from backup.

To minimize the risk of data loss that is caused by compromised fault tolerance,

make frequent backups of all logical volumes.

Replacing hard drives

The most common reason for replacing a hard drive is that it has failed.

However, another reason is to gradually increase the storage capacity of the

entire system.

If you insert a hot-pluggable drive into a drive bay while the system power is on,

all disk activity in the array pauses for a second or two while the new drive is

spinning up. When the drive has achieved its normal spin rate, data recovery to

the replacement drive begins automatically (as indicated by the blinking

Online/Activity LED on the replacement drive) if the array is in a fault-tolerant

configuration.

If you replace a drive belonging to a fault-tolerant configuration while the system

power is off, a POST message appears when the system is next powered up. This

message prompts you to press the F1 key to start automatic data recovery. If you

do not enable automatic data recovery, the logical volume remains in a ready-to-

recover condition and the same POST message appears whenever the system is

restarted.
