If no rebuild is necessary, the command will be ignored. To start a rebuild manually, type: arrayrbld -r Setting Rebuild Priority The rebuild priority determines how quickly a rebuild completes. It allows you to balance the servicing of host I/Os with the rebuilding of the disk array. The same rebuild priority is used for both auto rebuilds and manual rebuilds.

Windows NT
Rebuilding the Disk Array
To maintain data redundancy in the event of a disk failure, it is important to rebuild the disk array as soon
as possible. Auto Rebuild does this automatically, and it is enabled by default.
If you want more control over the rebuild process, you can disable Auto Rebuild. This will allow you to
manually start a rebuild at the time you choose. A Rebuild impacts disk array performance while it is in
progress, so before starting a rebuild make sure the appropriate Rebuild Priority is set. See “
Setting Rebuild
Priority
” in this chapter.
For convenience and maximum protection in the event of a disk failure, Auto Rebuild is enabled by default
on a new disk array. For information on disabling Auto Rebuild, see “
Changing Disk Array Configuration
Settings
” in this chapter.
Rebuilding the Disk Array Manually
If you have chosen to disable Auto Rebuild, you will have to start the rebuild manually. The rebuild will
begin immediately and continue to completion. If no rebuild is necessary, the command will be ignored.
To start a rebuild manually, type:
arrayrbld -r <array-id
>
Setting Rebuild Priority
The rebuild priority determines how quickly a rebuild completes. It allows you to balance the servicing of
host I/Os with the rebuilding of the disk array. The same rebuild priority is used for both auto rebuilds and
manual rebuilds.
To set the rebuild priority, type:
arrayrbld -P { high|low } <array-id
