Creating Pools with the Express Method
To create pools:
1 Select Express configuration..., then click Next.
2 Review the information that is displayed.
To exclude specific disk drives or to make other changes, click
Modify pools. See
Step 5 on page 39 for more information.
3 Click Apply, then click Yes to confirm.
The pool is created. You can provision storage from a new pool immediately,
without waiting for the build/verify process to complete.
Caution Don’t remove any drive included in the pool while the pool is building.
Adding Capacity to a Pool
You can add disk drives to an existing pool to expand its capacity without changing
its RAID level. When you expand a pool, stored data is distributed (or migrated)
across all the original and new disk drives.
You can expand pools with any of these RAID levels: RAID 0, RAID 5, RAID 6, or
RAID 10. The maximum supported size for a pool is 512 TB.
To increase the capacity of a pool:
1 In the Logical Devices View, select the pool you want.
2 In the Actions menu, click Expand or migrate pool.
The wizard opens to the Choose RAID Level window. (Don’t change the RAID
level.)
3 Click Next.
The Modify Pool window opens.
4 Select available disk drives to add to the pool. Unavailable disk drives are
indicated by blue check marks.
5 Click Next, then review the pool settings.
6 Click Apply, then click Yes to expand the pool.
The capacity of the pool is increased. You can use the new storage space right away.
Changing a Pool’s RAID Level
If your requirements change, you can change the RAID level of an existing pool.
You might want to do this to increase the capacity or performance of a pool, add
redundancy to a pool, or to make disk drive space available for other uses.
