Replacing SCSI card in Microsoft Failover cluster IBM hardware

I have built a cluster using:

2 x IBM X345
2 x ServeRAID 6M cards
Windows 2003 Enterprise
Firmware - 7.12.07
BIOS - 7.12.07
Driver - 7.10.18
ServerRAID Manager - 7.10.18

We recently had the 6M card in the secondary cluster node fail. After replacing the card and bringing all the BIOS and Firmware up to sync with the primary node's card. I loaded up the mini config during boot and copied the configuration from the drives to the new SCSI card. Upon booting the secondary node it takes control of the RAID arrays causing all the drives to show as defunct.

What is the proper procedure for bringing this second node back online without disrupting the cluster?

Did you change the SCSI ID on the serveraid in thhe second node? http://publib.boulder.ibm.com/infocenter/director/v5r2/topic/serveraid_5.20/fqy0_bk_serveraid_mgr.pdf tells how to change the SCSI inistiator id. If not both controllers will have same ID on SCSI bus, you normally set it to ID6 but check there's no disk at that ID first.

Fantastic, I completely overlooked setting the initiator back to 7.
