To give some greater context, see my previous post.
When I was initially planning on how to setup these drives, I configured them with the HP P410 RAID utility as a RAID-0 array. I made the decision to not live such a risky lifestyle and blow away the array and configure it for RAID-1. I want to build a solid homelab that will assist me in aspects of systems administration so I didn’t want to risk everything by running the wrong array.
Anyways, when I booted into VMware, I was unable to add the VMFS datastore after setting it to RAID-1.
I received the following error:
“Failed to create VMFS datastore – Cannot change the host configuration”
I did a bit of searching around and tried to re-scan the datastore and get vmwre to detect it but nothing was working. I soon came across the following VMware communities post here, user Cookies04 was on onto something.
The user identified a very familiar scenario to mine.
” From what I have seen and found this error comes from having disks that were part of different arrays and contain some data on them.”
That’s the exact thing that happened to me. RAID-0, some VMware data, then RAID-1.
I proceeded to follow the three easy steps and my issue was solved.
I didn’t really have to post all of this but I wanted to in case somebody were to come across my page and had the same issue.
The interwebz if filled with many many solutions for issues. I’m just adding what’s worked for me.
