Problems with disk mirror after changing hardware

[Chris Coates_1]

I have a Proliant 5500 that is being retired, and I need to move the physical disks to a DL380G1.

I pulled disk 0 on the 5500 and placed it in slot 0 on the 380G1. Since the 5500 has a 221 controller and I am using the integrated controller on the 380G1, the 380 recognizes the disk and allows me to boot to the disk, the Windows OS comes up fine. The problem is that with just the single disk in slot 0, I was expecting the server to note that disk 1 was missing and allow me to place a disk in slot 1 on the 380, after the RAID controller was detected and I hit F2, and the mirroring would begin.
After hitting F2 I insert the disk but the server turns the disk off. If I go into the ACU It sees the disk in slot 1 as unassigned and the other half of the mirror as missing. It says until I replace the missing disk (SCSI Port 1 SCSI ID 1) I cannot make changes.
I suspect that this is because there are 2 SCSI busses on the 5500 and only 1 on the 380G1.
If I reboot the server the integrated controller is found and it says that I need to replace SCSI Port 1 SCSI ID 1.

This is something that I did about a year ago and I got past this, but don’t recall how. That server is working fine. I don’t believe this a supported action by HP but I still need to do it and know it can be done.

I have tried clearing the NVRAM and re-running the System Config Utility.

Any help is appreciated.

Thanks
