ESXi 6.5u1 - RAID replacement dropped Datastore

Hi Guys,

New to the forum but here goes:

We have a new ESXi 6.5u1 install that was running reliably (albeit slow) on a non-cached RAID configuration.

Replaced RAID card with cached unit, booted server, updated RAID config to the new controller and booted into ESXi without an issue.

However.. the Datastore vanished and the VMs are in limbo without it.

The only work-around that I could find suggested using the vSphere Client to connect in and re-add the Datastore (without formating it), but 6.5-U1 removes that option.

Any other gurus out there able to offer a solution for 6.5u1?

Any assistance would be appreciated.

Mike
