If you are accessing the compute node from a remote location
- Make sure that all applications are running (no applications are hung).
- Attempt to log out of the system and log back in.
- Validate the network access by pinging or running a trace route to the compute node from a command line.
-
- If you are unable to get a response during a ping test, attempt to ping another compute node in the chassis to determine whether it is a connection problem or compute node problem.
- Run a trace route to determine where the connection breaks down. Attempt to resolve a connection issue with either the VPN or the point at which the connection breaks down.
- Restart the compute node remotely through the management interface.
- If the problem remains, verify that any new software has been installed and configured correctly.
- Contact your place of purchase of the software or your software provider.
