Expanding Pool Capacity

Using Adaptec Storage Manager, you can expand the capacity of a pool by adding
one or more disk drives (see page 90). You can expand pools with any of these
RAID levels: RAID 0, RAID 5, RAID 6.

Changing from One RAID Level to Another

Using Adaptec Storage Manager, you can change a pool's RAID level. Changing a
pool's RAID level may also increase its capacity. This table lists supported
migrations:
From RAID Level
Simple Volume
RAID 0
RAID 1
RAID 5
RAID 6
RAID 10
You can also migrate from RAID 1 or RAID 5 to RAID 0. If the pool has a spare
drive associated with it, the RAID 0 pool retains the spare drive.
Migrations that do not involve a change in RAID level are also supported in
Note
RAID 0, RAID 1, RAID 5, and RAID 6. See "Expanding Pool Capacity" on page 200
for more information.
