Current configuration:
HP Proliant ML350e with Smart Array card
ESXi 5.5 from HP Custom ROM
Boot from 4GB SataDOM
Two logical arrays on Smart Array (LUN 0/Datastore 1 and 1/Datastore 2)
Windows Server 2012 (DC) installed on Datastore 1
Windows Server 2012 (TS) installed on Datastore 2
I have installed a new server from the HP custom ROM and on reboot Datastore 1 is not mounted. The datastore can be found then mounted by adding storage and keeping the signatures. Datastore 2 is mounted on boot and loads the VM.
