To work around this issue, unexpire the root password:
SSH (Putty / OpenSSH) into the appliance using the expired root account credentials.
Note: If you do not have the root password, follow the instructions under this article: "How to reset or recover the root password on a VMware vRealize 7.x appliance"
Reset the password by running the command: passwd root This resets the password for another 365 days. To extend the expiry date see the command below: chage -M numOfDays root Note: This may pose a security risk so ensure that you verify with your internal policies prior to setting. To check the password settings, run this command: chage -l root
