If you run the Cluster> show command when a slave node is in the restart, shutdown, or crash state, the slave node throws an exception

In a particular flow, if the node that is in the restart, shutdown, or crash state is running, the system calculates the running node list. It returns unreachable on SSH when the command starts to calculate the CPU or network statistics. The internal library throws an exception.

Once the state of the node is in shutdown, restart, or crash state, the slave node changes from RUNNING to FAULTED in Veritas Cluster Server (VCS). The Cluster> show command resumes its normal behavior. That is, it does not show any exception and gives an expected output.

Workaround:

There is no workaround for this issue. The system recovers itself. You need to wait for some time and run the Cluster> show command once again.
