For now, I'm only experiencing such error in Solaris10. Launching the Veritas GUI was not a problem, the error surface when I tried connecting to the current server via the Veritas GUI manager after key-in the root password.
According to the solution that I've found, this was due to the VEA not being starts.
Check the VEA status
# /etc/init.d/isisd status
The output
Current state of server : NOT RUNNING
Start VEA
# /etc/init.d/isisd start
Once the VEA started properly, you should be able to get connected to your Veritas GUI manager.
