Data Backup and Recovery Discussions
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
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.
Thanks, just right on time,
For reallocation command to be successfully run is there an space restrictions that we should have on the Aggregates?
Thanks for your feedback.
