Recently, I had to add some hardware to an HPE ProLiant DL380 server. Ok, it wasn’t me because this server runs in a location about 3600 miles away from me. But the engineers on-site completed this task. The engineers added some memory and more disks to the server. My task was to add the newly installed disks to the existing ESXi datastore. This was (still is) a standalone ESXi server, as we say a black box server. It’s a standard HPE ProLiant server with local disks and an SD-Card as ESXi boot disk and it is centrally managed in a vCenter. Local IT persons have limited access to vCenter just to manage their workloads on that specific ESXi black box. There isn’t running much on these black boxes, most of all an SCCM distribution point because lacking enough bandwidth. But anyway, that’s not the topic here.
I want to show you what steps I’ve missed in the first attempt and how I’ve managed to fix it.
As there is not much running on this black box server, it was easy to schedule a maintenance window to shut down the workloads and also the ESXi server, so the engineers onsite were
