Hello,
I have a Suse 10.2 system that is running with a very high CPU usage percentage. If i do a "vgs" or a "fdisk -l " my request hangs. We recently had some SAN work done and i believe something in the disk subsystem is confused.
i have no one process that i feel i can point to. I'm considering rebooting the system. Anyone have any suggestions prior to my just doing a reboot?

Thanks.
