show
This command shows summary information about the specified unit /cx/ux. If
the unit consists of sub-units as with the case of RAID-1, RAID-5, RAID-10,
RAID-50, then each sub-unit is further presented. If the Auto-Carving policy
was on at the time the unit was created and the unit is over the carve size,
multiple volumes were created and are displayed at the end of the summary
information. Similarly, if the unit was created using the 3ware BIOS utility
3BM and a size was entered in the Boot Volume Size field, multiple volumes
were created and will be displayed. (Note that a volume created using the
Boot Volume Size feature does not have to be used as a boot volume.)

One application of the /cx/ux show command is to see which sub-unit of a
degraded unit has caused the unit to degrade and which disk within that sub-
unit is the source of degradation. Another application is to see the source and
destination units during a migration.
