6.When you are done, click the Next button.
7.Select a new RAID Level, if desired.
8.To expand the disk array's capacity, check the Expand Capacity box.
9.If you checked the Expand Capacity box, enter a number into the Capacity field and select the appropriate unit of measure (MB, GB, TB).
10.Under Capacity Usage, highlight the logical drive whose RAID level you want to change or whose capacity you want to expand.
11.Click the Update button.
The logical drive changes to reflect your choices.
12.Update other logical drives using the same method.
13.When you are done making the changes, click the Next button.
14.Click the Submit button to begin Migration.
Rebuilding a Disk Array
When you rebuild a disk array, you are actually rebuilding the data on a replacement physical drive.
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.
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, select 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.
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.
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.
To start Media Patrol:
1.Click the Subsystem 
icon in Tree View.
2.Click the Disk Arrays 
icon.
3.Click the Disk Array 
icon.
4.From the dropdown menu the Background Activities tab, choose Start Media Patrol.
5.Click the Start button.
Running PDM on a Disk Array
Predictive Data Migration (PDM) migrates data from the suspect physical drive to a spare physical drive, similar to Rebuilding. But unlike Rebuilding, PDM acts before the disk drive fails and your Logical Drive goes Critical.
To start PDM:
