Action
If you are in the same location as the compute node, complete the following steps:
1. If you are using a KVM connection, make sure that the connection is operating
correctly. Otherwise, make sure that the keyboard and mouse are operating
correctly.
2. If possible, log in to the compute node and verify that all applications are
running (no applications are hung).
3. Restart the compute node.
4. Make sure that any new software has been installed and configured correctly.
5. Contact your place of purchase of the software or your software provider.
If you are accessing the compute node from a remote location, complete the
following steps:
1. Make sure that all applications are running (no applications are hung).
2. Attempt to log out of the system and log back in.
3. Validate the network access by pinging or running a trace route to the compute
node from a command line:
a. 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.
b. 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.
4. Restart the compute node remotely through the management interface.
5. If the problem remains, verify that any new software has been installed and
configured correctly.
6. Contact your place of purchase of the software or your software provider.
An unusual smell might be coming from newly installed equipment. If the problem
remains, contact Support.
