I've been reading through the Prime Collaboration Deployment Admin Guide 10.0 and I'm trying to figure out why the NFS mount is needed from the PCD Server to the ESXi? When you upload your image to the PCD /fresh_install Dir it's on the PCD Server. When you run the Migration tasks you run that from PCD, so why does ESXi need the NFS mount?
It looks like the NFS mount is actually just the SFTP datastore on PCD. This allows the vm to get the media (.iso files) from the host in order to perform the upgrade/migration.
Can PCD use ISO's stored in a folder on a "traditional" datastore (i.e. an existing datastore that is presented via Fiber Channel SAN) so that PCD does not need root access to the VMware ESXi host?
I don't think so... I was looking for that functionality myself. Either way PCD would still need access to the ESXi host in order mount the ISO and shutdown/restart the VM, etc.
