Hi
I am upgrading to ESXi 5.0 from ESX 4. It is 4 node esx cluster. And, there are some MSCS guest VM cluster running on these esx hosts with RDMs attached.
I just need to confirm the steps as given below (specificaly for dealing the MSCS clustered Virtual Machines)
1)Move all the VMs off the ESX host; standalone VM can be vMotion migrated and for MSCS clustered VMs shutdown the passve node running on this particular ESX host and migrate it to another host.
2) Take out this ESX hosts ; rebuild it with ESXi 5.0 and add back in the same esx cluster and configure it on the vCenter and dvswitch; and ensure it is able to see all the storage devices including the RDMs(for MSCS clustered VMs)
3) Now migrate the MSCS clustered VM passive node back to the ESXi 5 host we just rebuilt.( and then upgrade VM tools and hardware etc
4) Then upgrade the second ESX hosts in a similar way as mention in step 2.
5)Then migrate the active node of the MSCS clustred VM to this second ESXi 5.0 host. (upgrade the VM tools and hardware.)
And then upgrade all the ESX hosts one by one in a similar fashion. Please advice if this approach is god to go
Many thanks in advance
Cheers
