I have a BCS Model 7779 that I originally had only a JS12 blade in it. There was a single storage module and all 6 drives were assigned to the JS12. The JS12 has two IBM i partitions and a Linux partition running on VIOS. I'd like to replace the 39Y9193 with a 43W3630. I'd also like to add another storage module and 6 drives. I currently have an HS22 and an HS21 in the chassis but they only have the local drives in them and I'd like to connect the HS blades to the additional storage. Those blades also have SAS Expansion cards in them.
The question is: If I add the drives and replace the SAS Connectivity Module with the SAS RAID Module, can I retain the configuration I have for blade 1 (the JS12) and create a single raided volume using the remaining 6 drives in the new storage module? Can I do this without having to save and restore the VM's I have running on the JS12? I'd like to disrupt as little of the config as possible. If I can swap the SAS modules and then assign the 6 drives in storage module 1 back to the JS12 and still have it work, that would make for the easiest transition.
Am I on the right track or will I need to rebuild the storage and re-install the OS'es after swapping the SAS modules?
