Automated Pool Error: View Composer Fault: VMware.Sim.Fault.VcDatastoreInaccessibleFault
Issue: When setting up a linked-clone pool you get this error when creating the replica
There are new ESX hosts in the cluster don't have access to all the LUNs
Note that this also happens even if this new host is in maintenance mode.
Resolution:"The solution is to move the host out of the cluster until it can see all the needed datastores."

All I did was create a temporary cluster and drag and dropped my new esx hosts into it and then I was able to create my replica disk.
