Privileged Access Management (PAM) Admin successfully upgraded 3 out of their 4 server to 4.2.1/4.2.0. However one server, which the attempted to upgrade 3 times consistently fails with the following errors in VMware Console log:
In PAM Console see the following messages:
Starting PAM. . .
Waiting for MySQL to get in running state...
Waiting for MySQL to get in running state for x minutes.
Eventually, the PAM Splash screen will come up, but you will not be able to get to any PAM UI's.
On a very minor subset of PAM servers the permissions and/or file structure of our PAM DB is incorrect.
You will have to revert the snapshot of the PAM Appliance to its original PAM Version.
Then open up a support case, in which Support will have to SSH into the PAM Appliance and fix the permissions/symbolic links of our PAM DB.
