Hi All,

Is there any way we can find the volumes having least IOPS. We have external SR through which we can list max 16 volumes having highest IOPS.

But we need details of volumes having least IOPS.

So any idea??


Thanks in advance.

Sorry not sure how you'd get that from ESR without some kind of manual export (excel client maybe)

You could use statvlun for a real time view, but really a histogram would be better than stat so you could just count the numbers in the buckets over a period of time, unfortunately histvlun provides only I/O size and service time.

"statvlun -vvsum -d 5 -sortcol 4:7,dec" will sample every 5 seconds and sort by IOps & Bandwidth

For internal system reporter something like :-

"srstatvlun -attime -btsecs -24h -hires -sortcol 4:7,dec -groupby VV_NAME" same for this but 5 min samples going back 24 hours

Use "setclienv csvtable 1" if you want to export to CSV.
Use "setclienv csvtable 0" to turn CSV output off.
