For log devices, click Log Profile and select either the mirrored or striped profile. If you
allocated an even number of log devices to the pool, select the mirrored profile.

Creating a Storage Pool (CLI)
Storage pools store data and can be created during or after initial configuration. Pools can
contain data drives, read cache devices, and log devices. The following task assumes that
initial configuration has been completed. Creating and configuring a storage pool is a two-step
process. First, the storage devices are verified for presence and minimum functionality, and you
assign drives or even entire disk shelves to the pool. Second, you select a profile for the drives
based on your business needs. If for some reason a pool is unconfigured, you can import it as
described in “Importing an Existing Storage Pool (CLI)” on page 93.
