Migrating a Logical Drive’s RAID Level
The term “Migration” means either or both of the following:
• Change the RAID level of a logical drive.
• Expand the storage capacity of a logical drive.
Before you begin a migration, examine your current disk array to determine
whether:
• The physical drives in your array can support the target RAID level.
• There is sufficient capacity to accommodate the target logical drive size.
If you need to add physical drives to your array, be sure there are unassigned
physical drives are installed in your RAID system before you begin migration.
See “Migration” on page 96, “RAID Levels” on page 261 and “RAID Level
Migration” on page 275.
