MSA500 replaced failed drive becomes unassigned drive in ACU

The MSA500 is a part of a 2-node cluster with HP Proliant DL380G3 servers.
One of the HDD has failed in the MSA500. As we have got original spare HDD, we have replaced the failed disk.
After the replacement the array is still in degraded mode and the new disk is not joined automatically to the array.

We have checked the system with the HP Array Configuration Utility and with the HP System Management Home Page installed on the cluster nodes.
We have encountered a strange situation, the System Management Home Page displays 15 HDD in the system meantime there are only 14 slots.
It seams that the system did not forget the failed disk after it had been removed.

I have attached a screenshot for more detailed information.
It shows that the array is degraded and there is a new HDD in slot 7 but the disk has not been added to the array automatically (neither possible to add manually).

It shows also that the management application enumerates 15 disks.

We have tried to check the status of the array and solve the problem with the software of the array controller during the bootup procedure (pressing F8 to enter the controller BIOS) but it is not possible to fix this messed up situation.

Anny advise?

Re: MSA500 replaced failed drive becomes unassigned drive in ACU

IF you look carefuly, the failed drive is shown as Port 1, drive ID 11, which does not exist on a MSA500.
The ID assignments are Port 1 ID 1-7, and Port 2 ID 8-14.
What happened here was not a drive failure, but a RIS data corruption. The RAID changed from having Port 1 ID 7 as member, to having Port 1 ID 11. Since this device does not exit in a MSA500, the controller does not find it and shows it as failed.
But all disks are OK, the problem is the RAID.
What you can do is add Port 1 ID 7 manually to the RAID and bear with the inexistent Port 1 ID 11 as being marked as failed.
