Hello,
till now we've used our Hitachi SAN AMS2100 only with ISCSI protocol.
Now we've connected the SAN also via FC connection to the Vmware infrastructure.
The SAN is presenting 9 LUNs (1TB each) with several VMs (production) on them.
The question is: are there any safe procedure the can help to "remap" the datastores without moving out the VM to another SAN ?
Example: is it possible to unmap the datastore via Iscsi (without destroying it) and then remap it via FC discovery ?
This will avoid VM migrations, obviously the VM will be powered off when detaching the iscsi mapping, but can they remain registered in vcenter, or we have to re-register them?
Any suggestion will be appreciated.
Bruno
