UNITS
Displays information for all units configured to the controller.
If the underlying container is a mirrorset with DT_SUPPORT, it displays the
ERROR_MODE setting. It reports if the mirrorset is failsafe locked or normal. A unit
that is inoperative due to the failsafe locked condition will only be shown at the unit
level (not mirrorset level). Since WRITEBACK_CACHE is not an allowable switch
for DT_SUPPORT mirrorset, the switch is not displayed.
In addition to the unit name you defined for the unit, the information includes the
unique 128-bit subsystem unit ID. This ID consists of the controller node ID plus a
64-bit unit ID generated by the subsystem. You name the units, however, the
subsystem identifies them internally using this identifier.
A unit on controller 1234 5678 9ABC EF00 would have an ID like the following:
1234 5678 9ABC EF00 0001 0001 3056 00D2
Each single disk unit or storage device in your subsystem is assigned a unique unit ID
number. The controller constructs a unit ID number for each device you add to the
subsystem. The ID number consists of the controller's worldwide node ID and a
unique, internally generated serial stamp. You cannot set or change unit IDs.
Unit ID numbers stay with the unit when you move the unit from one slot to another
in the enclosure.
