io Stress on logical drive

kaganis · 08-08-2005, 01:09 PM

I am running RHEL 3 Update 3 and I am connected to a storage array.

IAs a test, I would like to stress the LUNs in my SAN environment. What would be a good tool for this purpose and where could I get it.

Also, I was advised that you could use `dd` to do this as well (simple IO writes), however after looking at the syntax, I can't see how to get it to loop the writes to the Lun and then delete what it has written.

Any assistance would be appreciated.

while dd if=/dev/disk1 of=/dev/disk2; do echo "Still at it"; done

And then there's bonnie
