DM IM hp_3par probe how is the calculation for virtual volume utilization QOS_VIRTUAL_VOLUME_UTILIZATION made? 

Resolution

The data returned from the command 'statvv -iter [email protected]!showvv -s' is used to make the calculation. 

This is found in the probe folder $\Nimsoft\probes\storage\hp_3par\data\<device IP address>_statvv_-iter_1___showvv_-s.txt

These are the columns used:

Adm_Rsvd_MB, Adm_Used_MB, Snp_Rsvd_MB, Snp_Used_MB, Usr_Rsvd_MB, Usr_Used_MB 

utilization = (used*100)/total;

Where total is sum of Adm_Rsvd_MB, Snp_Rsvd_MB and Usr_Rsvd_MB
and used is sum of Adm_Used_MB, Snp_Used_MB, Usr_Used_MB

Sample file data:

***********************command*************************
statvv -iter [email protected]!showvv -s
***********************stdout***********************

Scroll down to the second section of the file for:

                                           ----Adm-----      ----------Snp-----------          --------------Usr--------------                                         
                                           ----(MB)----       ---(MB)---- -(% VSize)--   ------(MB)------- --(% VSize)-- 

Note: some of the unsupported 3par device models will not have a ----Adm----- and so it is not possible to calculate QOS_VIRTUAL_VOLUME_UTILIZATION.
