So this is my first attempt at ESXi 6.5 and I wanted to see if anyone else has seen this. The hosts are ESXi 6.5 HP Custom image and everytime I reboot the host, the data stores disappear. Everything looks fine under Storage adapters and Storage Devices but the Datastores are just not showing up. However if I run a rescan of all storage adapters everything comes back just fine? I have never seen this with any previous version of ESX before. I thought that it could be an issue with out of date firmware which I then went to HP's site and downloaded the latest Firmware available and applied it to one of the 3 in my cluster, but no change.
The Hardware is HP ProLiant BL460c Gen8.
