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.
The unit information shows the percentage completion of the processes
associated with the unit with %RCompl (percent Rebuild completion) and
%V/I/M (percent Verifying, Initializing, or Migrating).
Unlike other unit types, RAID-6 may potentially have 2 or more parity drives
and can tolerate two or more failures within a unit. As a result, an added
notation is used to describe %RCompl and %V/I/M, and these are (A) and
(P). (A) denotes that the percentage completion of the process is for the
current active process, and (P) denotes that the percentage completion of the
process is for the current paused process.
Example:
/localhost> /c0 show unitstatus
Unit UnitType Status
---------------------------------------------------------------------------
u0 RAID-6 REBUILD-VERIFY 50%(A)
Here, the RAID-6 unit u0 is in the Rebuild-Verify state, with percentage
Rebuild completion of 50% and is the current active process. The process of
either Verifying, Initializing, or Migrating is at 70% and it is a paused process.
For the unit display:
//localhost> /c0/u0 show
