Ran a test today....  I did some "store to disk" operations to consume my
disk space.  As the STORE operations progressed, the CV SCM "Capacity"
number tracked fairly closely with the "discfree c - in use" number.  When
most of my space on the four LUNs was gone, I purged the disk store files.
The following is what I'm observing now:

      From Command View SDM               From Discfree C
            LUN         Capacity                LDEV        "In Use"
            1           73%                     1           10%
            2           95%                     2           9%
            3           95%                     3           8%
            4           95%                     4           9%
            5           0%                      30          0%
            6           0%                      31          0%
            7           0%                      32          0%
            8           0%                      33          0%
            9           0%                      34          0%
            10          0%                      35          0%


It looks like I only get to see the maximum usage from Command View SDM.  I
would have thought that a purge operation would have been reflected within
Command View SDM as well.

Actually, I have 6 other 36Gb LUNs defined in the VA7110 which are
currently 0% used.  (I'm still setting up the system, and haven't yet
restored those volume sets.)

I will admit I have not much idea of CommandView, but I am
speculating that what it tells you about the LUNs are the
percentages of the overall VA's capacity being used by
these LUNs.
