Ping the GSC, but there is a utility
(statit) that will help.

Subject: How to identify a hot
disk
So I am getting the
following when running sysstat –u. As far as I know nothing should
be hitting the array hard enough to drive disk utilization to 100%, much less
hold it there. What can I do to further determine what’s causing this?
All of my storage is
NFS based at this time.
