Migrating a RAID Level
RAID Level Migration is the ability to change the RAID level on one or
more system drives. This may require more or less space on the physical
drives. Any other logical drives are moved to make room for the size change.
This includes moving system drives to remove gaps between the system
drives that either exist before migration or those that would be a result of the
migration.
The following table (Table 4-1) describes the allowed migrations.
To migrate a RAID level, follow these steps:
1. Select Administration->RAID Assist on the menu bar or the RAID
Assist icon (see Figure 4-7).
2. Click the Manual Configuration button.
3. Click the Logical Drives tab, this is where you can edit a RAID level.
4. Follow Step 5 through Step 12 of “Expand Capacity” on page 4-30.
