vv performance

Post by oby »

Hi,

we have problem with high iops over 10-15 minutes on a specific volume on random time. Is it possible to find this specific volume which is causing high iops from hist data? May you give me a clue how the command should look like, please?

Thanks

System Reporter. Select High-Res for VLUN Perf Report. Next specify Beginning and End time when you see the spike in IOPS. Set Compare to VV and it will show you which volumes generated most IOPS.

Hi,

There are 2 more way you can find the particular LUN hving high IOPs.

1. Go to your Service Processor and run the Performance analyser.
(Either you can select default as all, or also you can specify the number of iteration needed and the time interval). It gives the Stat of all the VVs.

2. Run the command statvv -d <time> -iter <number>
This can also be used to find the Status of the VVs.

Regards,
KK
