Just looking for someone who might know why this could occur...

In OMSA, on my Dell 2950, there usually is only one "Physical Disks" child under "Enclosure (Backplane)" in the tree view. Currently, the tree looks like this:

Dell PERC 6/i Integrated

Connector 1 (RAID)

Enclosure (Backplane)
- Physical Disks (1:04 good, 1:05 removed)
Physical Disks (1:33 Ready but unused)

Normally it's like this:

Connector 1 (RAID)

Enclosure (Backplane)
- Physical Disks (1:04 good, 1:05 good)

From the front, 6 of 6 3.5" SAS drives are connected. The server is showing Slot 5 as bad and the disk as removed. It seems that the drive in Slot 5 is being sensed as external to the Enclosure. Any ideas why this would happen? Think I can get away with rebuilding the virtual disk by replacing 1:05 with 1:33?

Thanks.

UPDATE: The only options on the Physical Disk 1:33 were Assign as Global Hot Spare and Clear...

After clearing, I assigned it as the Global Hot Spare. This allowed the rebuilding of the virtual disk. Hopefully it won't fail.

I'm still unsure of the reason for this odd behavior. I'm checking the firmware next.
