Rolling back a vSphere upgrade

February 26, 2017 – 8:40 pm

Ahem… Being a vExpert doesn’t mean you don’t make stupid mistakes like everybody else…

I pushed an update to vSphere 6.5 on a host and tada! Purple screen… I rebooted, crossing my fingers that it was a one time thing but no, it came back. Then it dawned on me to check the HCL… The server is an HP DL585 G7 and it isn’t supported.

I opened a case with VMware to see if there’s was a way to recover without having to reconfigure everything (not the end of the world but…) And there is!

I was directed to this KB that points out that during boot there is a rollback feature! Never noticed/knew about that one. Been a while since I upgraded environments. Glad to see this!
