Manual Rebuild

You may manually replace a failed disk using the

REPLACE

command:

REPLACE PHYSICAL_DISK

<id> NEW_DISK <new-disk-id>

A replace operation is used to replace a failed disk with a healthy spare disk. The operation can take
several hours to complete depending on the size of the disk and speed of the replace operation. The
rate of rebuild can be adjusted (see Section

3.3, "Performance Management"

on page

for more

information).
