We installed our new Power 520 last night. First one in the State of ME! And I had things to fix in ESX.
The reason there was a problem, the HBA in the System i was moved. ESX thought I had attaches a SAN snapshot to the host, and it didn't see the original LUNS.
I had to resignatue the Storage. Go to Configuration, Advanced Settings, LVM, and change the Resignature to 1. Rescan, then change it back to 0. Now I don't know if I could have one this easier, but I didn't have many VM's, so I just removed all the unknow VM's from Inventory and added them back. It only took a few minutes.
I knew I was going to run into this, because I moved the HBA one time, a few months ago, and I had the same problem.
All in all, everything went great, now I need to find out if you can do System i Integration with a VIOS Partition.
I want to let anyone who is interested know that I started a group on LinkedIn for System i Integration with BladeCenter and System x. I'm hoping to get some people from the IBM Development team, some RedBook authors, Advanced Tech Support, etc people to join.
And that's exactly what I plan to do! Our new Power 520 just arrived, and we're probably putting it in this weekend. So what I'm going to do is brush up on my skills. I'm going to rebuild my ESX Hosts from scratch! I have an old x346 Stand alone server (it was the old ESX host) and I'm going to build that up again, move all the VM's over, and after we get the new CEC in, I will rebuild. I'm going to have 2 HBA's in the System i now, so I'm going to do multi-pathing on everything right from the beginning. And once I get it all up and running like that, I will move the VM's back over.
