Every few hours we get the following in /var/log/messages:

We are running CentOS 4.6 on Sun x4600 hardware with a connection to a NetApp filer. The box has 3 X 146 GB hard drives. We know that one of the drives (set in LSI as a failed Hot Spare) has failed but that is in slot 0 and should not be an issue here. Any ideas on what is breaking? Thanks, John
