HP Smart Array P600-Controller - Manual (Page 31)

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.
