We have a Cisco UCS server with 2 drives and using hardware RAID 1. It is running windows server 2003. We know want to run ESXi5 on this server, so the plan to implement this is as follows:
Pull the primary HDD as a precaution just in case we have to put it back, and then blow away the RAID config on the second disk. Load ESXi on the clean second disk.
The question though is this:
If I pull the first HDD, could I put it back with no problems if I had to?
Second question is:
If this works correctly, can I then put the disk back and reconfig for RAID 1 with the new ESXi hypervisor.
