Migrating a Disk Array
The action of migrating a disk array means either or both:
• Change the RAID Level
• Expand the storage capacity
For a list of Migration options and other important information, see “RAID Level Migration” .
Notes
• You can add physical drives to a RAID 50 or RAID 60 array
but you cannot change the number of axles.
• If you add an odd number of physical drives to a RAID 10
array, it will become a RAID 1E array by default.
To Migrate an existing disk array:
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, select Start Migration.

move them to the Selected list.
You can also double-click them to move them.

appropriate unit of measure (MB, GB, TB).
• Under Capacity Usage, highlight the logical drive whose RAID level you want to change or whose
capacity you want to expand.

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.
