prtdiag -v

I am running Solaris 8 on an E450. Slots 0 & 1 are occupied and mirrored using SDS.Slots 2 & 3 are empty. Slots 4, 5, 6, 7, 8, and 9 are occupied and are configured as internal RAID 5. These 6 disk are using a special backplane configured for internal RAID.

When I enter the prtdiag -v command, slots 0 & 1 have an [OK] for their Disk LED Status. However, all other slots appear as [Empty].

Disk LED Status:OK = GREENERROR = YELLOW

DISK 10: [EMPTY]DISK 11: [EMPTY]

DISK 8: [EMPTY]DISK 9: [EMPTY]

DISK 6: [EMPTY]DISK 7: [EMPTY]

DISK 4: [EMPTY]DISK 5: [EMPTY]

DISK 2: [EMPTY]DISK 3: [EMPTY]

DISK 0:[OK]DISK 1:[OK]

Does anyone know why the slots appear empty when they are occupied? Everything else appears to be working "normal".

Thanks for any help.

ah, the infamous dpt RAID card in the 450's...

because the disks on the backplane are behind the RAID controller, they don't show up as normal disks. use "/opt/SUNWhwrdg/dptutil -L all" to see what the controller has on it.

basically, rather than show disks c2t0, c2t1, c2t2... when you build a RAID 5 disk, it shows up as c2t0 and the actual physical disks are invisible to the system.

btw, those cards are rather buggy; we stopped using them when sun stopped selling them, for no apparently good reason. chief complaint: sometimes disks on the backplane fail for no reason, and then you can't replace it, or fix it.
