Performance Monitoring of MD3000i from Linux
During the chat Kristoffer had a couple of questions around the MD3000i. One of which was how do you monitor the performance from a Linux system? I checked with a good Linux friend of mine and he recommends the sysstat package (or RPM) which includes iostat.
Anybody else have a recommendation?

I had never used it before your question prompted me to do some investigation - but I put together a quick command line sript that will dump a sample of performance info into a file:
C:\Program Files\Dell\MD Storage Manager\client>smcli -n r2md3000i -c "set session performanceMonitorInterval=5;set session performanceMonitorIterations=5;save storageArray performanceStats file=\"c:\\cliPerfStats.csv\";"
You would need to replace the -n parameter with the name of your MD3000i array. The complete documentation for the SMcli is located here - http://support.dell.com/support/edocs/systems/md3000i/en/CLI/PDF/CLIMR.pdf
I'm going to work on putting up a new wiki page on this stuff in the next few days.
