SAN migration final

Well, as expected Murphy had to show up after everything had been going so well in the first part.

After connecting the ESX hosts to the new SAN we ran into what seems to be a documented problem: a LUN that is incorrectly detected as being a snapshot and therefore acces is restricted to that LUN.

This gives the problem that in the VI client you cannot see that Shared Storage resources. The solution is to flag LVM.DisallowSnapshotLUN to zero and rescan the drives. The problem we had is that ESX still thinks these are snapshot LUN’s. After some discussion we decided to remove all VM’s and re-add them to the inventory. This seems to work.

We will have to wait on final say from VMWare support what we do about this.
