Errors with Custom vCenter Appliance 6.7 Certificates and SRM 8.1 (Error 25239)

In this post I decided to talk about two topics regarding vCenter certificates. VMware has improved a lot, but there are still a few bugs and some strange errors. I will show you how to import new custom certificates into vCenter 6.7 and how to resolve an error 25239 installing SRM 8.1. I had this error in a customer and the troubleshoot was quite difficult and the problem was certificate related. So here are my notes about the two topics:

• Installing custom certificates into vCenter 6.7 and troubleshooting
• Installing SRM 8.1 with custom certificates in vCenter 6.7 and troubleshooting

Import Custom 3PAR SSMC Certificates

This is the web based version of the classic 3PAR Management Console application (if you don't use it already, you might know that the old versiont is discontinued).
Today I will show you how to change the default certificates from 3PAR SSMC in a windows platform. You can use external or internal certificates from your Certificate Authority.

All the tools you need to complete this task are pretty well already on the server where you installed the SSMC software.

I think from another post I read that when you upgrade the SSMC version this will overwrite the certificate and you will have to do this again, i have not tested this yet.

Let's see how to do it!
