Unbind request failed because it was rejected by the peer SP board.

Hi,

I have inherited a PowerEdge 6450 containing 2 x Qlogic QLA2200 cards which are connected to a PowerVault 560F containing two SP boards.

The Qlogic cards are connected to Port A on one SP board and Port B on the other.

The PowerVault used to be connected to two identical PowerEdge servers, but one of these has been used elsewhere, so I'm left with one.

I assume I have the cabling correct as I can mount the drives fine, I can also see the data that was previously being used on the Powervault, but I need to reconfigure the drives from the current setting of 2 drives in a mirrored partition and the remaining 5 drives in a raid 5 configuration, to have all drives in a raid configuration.

When I use OpenManage Data supervisor and try to unbind the LUNs I get the error: LUN 01: SP B: Unbind request failed because it was rejected by the peer SP board.

I may be doing something stupid but I can't figure out why I can't remove the current configuration, any help on this would be very gratefully recieved as I am just about the throw the lot out of the window.

Many thanks,

Richard.
