Suggestions on moving folders from internal disk to SAN(11.31,rx7640)

[Deepak Seth_1]

Bill / Manoj/Rudolph - Thanks for the reply.

I did look many time i/o by FS , but how to find the top processes for high phy i/o ? All
the time the top system processes are for oracle / erp application which is on SAN anyway .

Also is there way to collect glance data since this server is used by Asia and they usually comes
to work late evening.
Boot disk is hardware mirrored - so no overhead from o/s side

application logs/tmp files are going to SAN file system - confirmed

If i could figure out a way to find the top high i/o processes for all boot file systems , then
at least i can troubleshoot it better.

Any way to do that .

We do have BMC Patrol also , but can't be of much use either.

Try '/opt/perf/bin/extract -gapdznuy -xp d-1 -r /vat/opt/perf/reptfile' command to create performance metrics text files for the previous day (creates in your current directory). The xfrdPROCESS.asc file shows processes that exceed limits set in config file. Look for 'D' (disk) in the "Interest" column. It won't tell you what filesystem had high i/o, but it is a start. Then you can look at xfrdGLOBAL.asc and xfrdDISK.asc for those specific time frames to compare.

Could be tedious, but it is a start.

To look at other times, the '-s mm/dd/yy hh:mm' and '-e mm/dd/yy hh:mm' switches can be used to look at data from other timeframes.
