the pool to which you want to add a device, enter set pool= and specify another
online pool.
Note - If you have a single pool, the pool name is not displayed, but it is selected.

Enter set and the disk shelf or controller ID, and the number of log or cache
devices to use.
ID "0" is the controller, and the remaining IDs are the disk shelves. In the following example,
2-log=1 allocates one log device from the second disk shelf.
hostname:configuration storage (pool1) verify> set 2-log=1
2-log = 1
Note - A value of "1-log=2" would allocate two log devices from the first disk shelf.
This example allocates one cache device from the second disk shelf.
hostname:configuration storage (pool1) verify> set 2-cache=1
2-cache = 1
