VMware.Sim.Fault.VcDatastoreInaccessibleFault

Error Message:
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."

Seems like View ignores or doesn't recognise that hosts are in Maintenance mode

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.
