Summary: While configuring my hosts, I ran into various issues. One host simply decided to stop talking and the hostd service became unstable. This meant vCenter could not access the ESXi host to manage it. One issue I had was that my hosts were missing PTR entries, but even w/ that resolved, I was still stuck w/ one host having issues. Quick Fix (Assumes no data on vSAN disks, use info at your own risk): Assuming you have vSAN claimed disks, this is how you can clear them up. Gather your list of disk on the host using this command: ls /vmfs/devices/disks Ones appended w/ a :1 or 2 are typically your vSAN disks, you can double check using this command: partedUtil getptbl /vmfs/devices/disks/naa.################# Return looks like this: Once you've determined which ones have those partitions, delete them: partedUtil delete /vmfs/devices/disks/naa.################# 1 partedUtil delete /vmfs/devices/disks/naa.################# 2 Once all have been deleted,
