Using Dell PERC RAID controller and NW 6.5 SP7

System hung this morning and we lost a drive in the array. Added new drive and rebuilt - OK.

When I bring up Netware now, it stays up/looks normal for about 5-10 minutes and then starts logging disk errors and then quickly deactivates the pools and the PERC RAID controller.

I saw errors on more than one pool. I'm thinking it may be the controller itself.

Dell is sending out the entire SCSI chain of parts.

Question - after all is replaced and if I still get pool errors, what can I do to fix?

I may not need to run it, but I'm trying to be proactive.

thanks in advance
