It was running VMWare ESXi 3.5, with a virtualised OpenSolaris machine inside of this this (as well as other machines) with ZFS as the filesystem. Anyhow, recently, after a reboot, on startup, ServerRaid complains that two logical arrays are offline. I have six SCSI drives in the machine - four 147 Gb ones, and two 72 Gb ones. From memory, the first four drives are in one array/logical disk, and the fifth drive is in one of it's own. The sixth drive isn't used. Yes, this was running in RAID 0...shame on me, I know. I booted up the ServeRaid Support CD, and the first and fifth drive were marked as defunct. The first drive (147 Gb) was listed as defunct drive, I/O subsystem error, and the fifth drive (72 Gb) as defunct drive, physical drive not found. When I right-clicked, I did see an option to mark the drives as online again (I'm not exactly sure how this would work with the physical drive not found?), however, there was a warning about data loss if I proceeded. I'm assuming this wasn't the option I wanted to recover the disks. What exactly does the IO/Subsy

Problem I have is that i keep getting 'defunct' disks, first failure there were seven drives defunct, they were brought back online ok but it took the raidmanager approx 24 hours to re-sync. This week another three drives have gone defunct, do not think it is a drive problem but maybe the raid controller (serverRaid-4Mx, anybody any suggestions?

I'm assuming this wasn't the option I wanted to recover the disks. What exactly does the IO/Subsystem error mean? If I mark online will it blow away the disk? Also, on the Lightpath console on the server, I have an orange error light on the DASD. I'm guessing that's not such a good sign? Or is it? Could it just be the ServeRaid card? Cause if so, I can just replace that..sigh, really hoping it is. Anyhow, how exactly should I proceed going ahead? Is there any way to recover either of the defunct drives (io subsystem or physical drive not found) back to their initial state? Or can I somehow rebuild the data from the remaining drives? (I suppose I'd have a corrupted VMFS (VMWare Filesystem) after that, and then I'd have to rebuild that, and then rebuild the virtual disk images inside of that...?) Any recomm
