•
SHOW UNITS displays all of the logical units and storagesets previously recorded
on the Logical Units Table
•
SHOW STORAGESETS lists all of the containers recorded on the Storagesets
Table:
•
Check logical unit Used by each of the storagesets

Check Name and Type of each storageset
•
Check devices in use by (Uses) each storageset

Power-on Host System
Now that the RAID Array 450 configuration has been verified, the host system may be
powered-on. Since the configuration has been modified, the system may require
additional time to complete it’s initialization. Once the system has completed the
bootstrap process login as the root user and continue to the next step.
