Hi All,
I would like to share couple of challenges that we faced during vCenter 5.1 U1 to U2 upgrade.
With my past experience - I thought it is easiest job to upgrade the vCenter Server (but it's not)
Challenges faced: (during individual components upgrade)
After SSO upgrade - service failed to start and SSOAdmin.log shows couple of unrelated error messages. (I fed-up to search those errors in google)
Solution: JRE Version mismatch - vCenter 5.1 U2 looking for higher version of JRE which is not prompted any point of time
I did the fresh installation of vCenter 5.1 U2 and copied the JRE folder version to problematic sever. (C:\Program Files\VMware\Infrastructure\jre)
Finally upgrade is completed but new problem. Team unable to open the vCenter console from remote locations and it is working fine locally.
Solution:
Install below hotfix on problematic server from where vSphere client is not working - In my case these are Windows 2003 Servers
