I was working on optimizing performance for MS SQL volumes and have quite a good feedback from DBAs
However I still want to know how to properly read out put of reallocate measure command.

What is the meaning  of string optimization.  all other are self explainable.

Reallocation scans are on
/vol/sqlserver1/lun.0:
        State: Idle
     Schedule: n/a
     Interval: 1 day
Optimization: 1
  Measure Log: n/a

/vol/vanibisqlwqa1_sprocket_insightstglog/lun.0:
        State: Idle
     Schedule: n/a
     Interval: 1 day
Optimization: 1
  Measure Log: n/a

thanks

This is fragmentation level. 1 is the best (no fragmentation). Max depends on Data ONTAP version, historically it was 16, today I think it can go up to 64.

So to summarize 1 is the best and 64 is the worst. Is it correct ?

PS is there any doc, TR etc... ?

Yes, correct. There is reallocation TR, do not have number handy.

Hello,

 

For reallocation command to be successfully run is there an space restrictions that we should have on the Aggregates?

 

Thanks for your feedback.
