Different output in the showspace with different options.

[dennischen]

Hi everyone, I have a question about the capacity of 3par

Why I get the different result of the est free space, when I use "-cpg" and "showspace -t rx -p -devtype FC -ha mag" options. Even the rawfree space is quit different. Thank you in advance

(You should wait until 3.3.1 where they made major improvements in the stats.)

Your two different ways of computing the space should provide similar results.

FC_r1 29413376 14706688

29945856 14972928  -t r1 -p -devtype FC -ha mag

FC_r5 27664384 20748288

29941760 22456320

FC_r6 27648000 20736000

29900800 22425600

Not sure why so much difference in RawFree for r5 and r6?

If you don't mention -cpg, showspace can't compute the space for SA vs. SD space nor for overhead for snapshots.
