While upgrading one of my vCSA (vCenter Server) to newer version VCSA 7, while connecting to source appliance I was receiving error A problem occurred while getting data from the source vCenter server.
This is typical issue of expired root password. due to this vCenter is unable to rotate the Logs based on the fact cron jobs are unable to run and vCenter is unable to be upgraded or patched.
To resolve this issue reset simply reset root password.
- Connect to the vCenter Server Appliance with an SSH session and the root user credentials.
- Use the following commands to get to the command prompt:
- shell.set --enabled true
- shell
- Change the root password using passwd command: .
- Verify the root account password has been changed using chage -l root command:
- In order to prevent this issue from happening again in the future, you could set the root password to never expire at the VAMI page or by running this command: chage -I -1 -m 0 -M 99999 -E -1 root
- Reattempt the upgrade again.
