I am not sure why but whenever I install a drive in bay 1 or bay 2 of my MSA50, ACU reports that two drives are present in the bay:

Duplicate drive in bay enclosure

This does not happen to any other bay but bays 1 and 2.

The disc enclosure is connected to a SmartArray P812 controller fitted with the latest firmware and ACU is latest version as well.

Using a different port on the P812 does not help either.

Am I right in thinking this isn't supposed to happen?

EDIT:

Here the configuration details from ACU CLI:

What does hpacucli "ctrl all show config detail" or the BIOS ACU say? –  Mark Wagner Sep 19 '13 at 1:06
    
Have you been able to do a restart and if so did the problem remain? –  Chopper3 Sep 19 '13 at 18:04
    
I've seen it before. It can happen. –  ewwhite Sep 19 '13 at 18:11
    
@Chopper3 Yes, the problem remains even between power cycles. –  Seb Boulet Sep 19 '13 at 19:16
    
@ewwhite Thanks for your input. It's good to know. –  Seb Boulet Sep 19 '13 at 19:18

I've seen this in situations where there are mismatched configurations... The P812 isn't really compatible with the MSA50. I've also seen this in cases where I had drive replacements/substitutions. Either way, you will not be able to see individual drive information, however alerts will indicate the proper slot if a disk fails.

An example... The array described below is 4 x 1TB drives in bays 0-3. However, they're reported as being in one bay. Annoying, yes...
