Hi, Was wondering if anyone knows what the Columns Grown_Usr_MB and Reclaimed_Usr_MB mean? Does this relate to how much the VV has grown and space reclaimed in a particular timeframe? Thanks. |

Looking at: Code: clihelp -col showvv it describes Quote: Grown_Usr_MB Amount of user space that the volume has grown. Reclaimed_Usr_MB Amount of user space that the volume has had reclaimed. This would have to be counters based on VV inception as there is no way to specify a timeframe for a showvv command. I would imagine this command might be useful to gauge how actively a volume grows/shrinks. To put another way, if a volume is only growing and never shrinking, do you want the overhead of having zero detect turned on? I've never used these values so I am only speculating. |

Does anyone know for certain how to evaluate these fields? For example: Name Adm_Used_MB Grown_Adm_MB Snp_Used_MB Grown_Snp_MB Usr_Used_MB Grown_Usr_MB VolX 4123 0 0 16896 3190875 14298112 VolY 5080 0 0 8192 7508887 12539392 VolZ 3450 0 0 33280 3047887 11702784 If these fields are recorded from volume inception, is it possible to reset the counters so you can monitor growth? Is there any other way to spot a growth trend, does the SSMC offer this? |

Could you not use srcpgspace and srvvspace and pull the historical data over a given time frame from the onboard system reporter database ? |
