Working with a RAID-5 Set

The CLI allows you to perform the following modifications to a
RAID-5 set:

Restore a RAID-5 set

Scrub a RAID-5 set

See the Flexible Array Storage Tool User’s Guide for a complete
description of RAID-5 sets and other container concepts.

The following sections describe how to perform these modifications.

Restoring a RAID-5 Set

The CLI allows you to restore a RAID-5 set that has one or more
dead partitions. You use the

container restore raid5

command to restore a RAID-5 set. This command does not always
succeed and should be used when all other measures to restore the
RAID-5 set fail.

The

container restore raid5

command may be useful if you

inadvertently remove a disk drive and then almost immediately put
it back. The act of removing the drive may cause dead partitions to
appear. You can then restore the RAID-5 set by using this command.

To work with restoring a RAID-5 set, you must understand:

The RAID-5 set restore attributes that you can specify
