SHOW UNIT displays the following information for the
                      specified UNIT:

                      - UNIT identifier (user-defined name)

                      - UNIT status

                      - Percentage rebuild

                      - List of the disks assigned as data disks to the UNIT

                      - List of the disks assigned as spares to the UNIT

                      - RAID level

                      - UNIT size

                      Format:
                              SHOW UNIT <unit_n> / <qualifiers>

                      SHOW UNITS:

                      SHOW UNITS displays information of all the logical
                      volumes configured on the controller. This command
                      does not take the parameter unit_n.

                      Note: From the CLI of MSA1000/MSA1500 controllers,
                            if ACLs are enabled for the UNITs with respect
                            to the connections (HBAs to which these
                            controllers are connected), then only those
                            corresponding UNITs will be visible to the
                            respective HBAs.

                            After the ACLs are enabled, if the user creates
                            any UNITs on these controllers (either from CLI
                            or MSA_UTIL), then the user will have to set the
                            ACLs explicitly for these UNITs to be visible.
