To Replicate or Build new Citrix servers we break mirror sets and then recreate them on a new server. This works perfectly for us. We are now moving off of these DL580's and will be using HP DL20 blade servers. The blades are using a 6I raid controller and the 580's are on a 5i. When I boot the OS on the blade I get a BSOD and the system simply reboots. I was told by HP that the 6i was was backward compatable. Has anyone been successful doing this? If so can you help me out?
