Hi,
We have a centralized EMC Unity storage which exposes the datastores to our ESXi hosts via iSCSi.
We are moving towards replacing all our iSCSi network to FC.
In order for that to happen, we bought a couple of new ESXi hosts which will be connected to the same storage machine (EMC Unity) and will be presented with the same LUNs as the "old" ESXi hosts.
Basically, the same LUNs are going to be exposed to the ESXi hosts via both iSCSi and FC.
My question is, if we currently have a few datastores with running VMs on them exposed via iSCSi, will I see the same datastores on the new ESXi hosts via FC (again, this is the same LUN we are talking about, just the connectivity protocol is different)?
I'm asking this, because if I do see the same datastore, I can then just vMotion all the VMs to the new hosts, and then disconnect the "old" ESXi hosts and "destroy" the iSCSi network (after all datastores and VMs will migrate to the new hosts . Is that true?
Thanks!
