Rebuilding Automatically
Normally, a disk array would rebuild itself using a hot disk drive, after going
Critical. However, if the Auto Rebuild function is disabled or no spare drives are
available, you must initiate the procedure.
To enable Auto Rebuild, see “Making Background Activity Settings” on page 52.
To create a spare drive, see “Creating a Spare Drive” on page 118.
For more information, see “Hot Spare Drive(s)” on page 237.
Rebuilding Manually
If a physical drive has failed, identify and replace the drive, then rebuild the disk
array as described below:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.
3. Click the Disk Array icon.
If there are multiple disk arrays, choose the icon with the yellow !.
4. From the dropdown menu the Background Activity tab, choose Start Rebuild.
5. Select the Source physical drive.
This is a remaining functional physical drive in the disk array.
6. Select the Target physical drive.
This is the replacement physical drive. The available drives are either HDD
or SSD, depending on the type of drives in the array.
7. Click the Submit button.
The Disk Array Background Activity tab shows the rebuild progress on the
replacement (target) physical drive. Depending the size of the physical disk
involved, this process will take some time.
To view more information, click the Rebuild on PDx link.
To set Rebuild priority, see “Making Background Activity Settings” on page 52.
Running Media Patrol on a Disk Array
Media Patrol checks the magnetic media on physical drives. When it finds the
specified number of bad blocks, it will trigger PDM. See “Making Background
Activity Settings” on page 52 and “Running PDM” on page 54.
You can schedule Media Patrol to run automatically, see “Scheduling an Activity”
on page 54.
