Install a New VCSA

Hi all. I’m in a bit of a sticky situation at the moment. We are using a Nutanix box that has 3 ESXi hosts on there.
Basically, I can’t access vCenter because of a 503 error. Also, the credentials my colleague left to access the VMware appliance aren’t working.

I was advised by Nutanix that I should install a new appliance directly on one of the ESX hosts (as the current one is installed).
How easy is this? I feel like I’ve nowhere else to turn so I’m willing to give it a go but I don’t want to break anything!

Thanks in advance

  1. Vcsa implies that it’s the Linux virtual server appliance. With this in low 6. versions, the Root password expires and then error logs fill the partition.

    By the time I got to it, I first had to reset the grub password, then I was able to boot single user and reset the root password, and delete logs so that it could possibly boot.

    Even then I ended up having to hand edit a bunch of files that had corrupted in the crash before it would fully boot, but I got it back up after about a day with no impact on the guests. Probably would have been faster to rebuild from scratch. See VMware kb for a starting point: https://kb.vmware.com/s/article/2149278
