Rebuilding Physical Device

Rebuild means incorporation of a new Physical Device to a Logical Drive after a Physical Device is replaced with the new

one due to occurrence of an event such as a failure. In general, the Rebuild is automatically started by a function of the

RAID Controller called standby rebuild or hot-swap rebuild. Accordingly, manual Rebuild is not required so often. If

required, use the Universal RAID Utility.

Manual Rebuild is available only in the Advanced Mode.

Executing Rebuild

Rebuild is executed for a Physical Device. The procedure of executing Rebuild is described below.

Rebuild can be executed if [Status] of a Physical Device is set to [Failed] and [Status] of the

Logical Drive using the Physical Device is set to [Degraded].

RAID Viewer

Use [Rebuild] in [Control] menu.

Step 1

Connect the Physical Device used for Rebuild to a RAID Controller at this timing if required. If the Physical

Device is connected completely, start the RAID Viewer.

Step 2 Click the Physical Device used for the Rebuild on the Tree View. Then

click [Rebuild] on the pull-down menu of menu item [Control].

Step 3 After the Rebuild is started, the progress

of the Rebuild appears on the Operation View.

At the completion of the Rebuild, [Status] on the

Operation View is changed to [Completed].

raidcmd

Use "rebuild" command.

Step 1

Connect the Physical Device used for Rebuild to a RAID Controller at this timing if required.

Step 2 Execute "rebuild" command with -op

option and the defined parameters.

-c : Number of the RAID Controller containing the

Physical Device for which Rebuild is executed

-p : Number of the Physical Device for which Rebuild

is executed

-op : Specify "start" to start Rebuild

> raidcmd rebuild -c=1 -p=3 -op=start

> raidcmd oplist
