Wasn't aware of the Adobe Flash kill-switch on the 12 of January, and had planed upgrading from 6.5 to 7.0 laster this month.
Sadly Flash stopped working yesterday.
And the vCenter HA configuration was only in the Flash version (at least it does not show up in my HTML version),
We have a vCenter with VCHA enabled (3 nodes) and need to get rid of that before upgrading til 7.0.
Any clues of what to do next?
Shut down the passiv and witness server and run vcha-destroy on the active vCenter node?
Found this witch is 4 years old. Still reliable?
vCenter Server High Availability (VCHA) PowerCLI 6.5 community module (virtuallyghetto.com)
I can't confirm the powercli, but there is a command set through direct console which was worked for me. The way is what you mention, power off and delete the witness and passive node, then destroy VCHA on the active.Just jump to the "Remove the HA cluster configuration" section on the following page:
The steps are right . destroy-vcha -f will do the rest
Also you can try the steps to make flash working but best is to upgrade to 6.7 U3 latest for HTML-https://kb.vmware.com/s/article/78589
