This post is about how to check the VRM and CNA node connection issue. Let's find below the procedure.

1. Check the FusionCompute portal alarm list if it still has the 'Heartbeat Communication Between the Host and VRM Interrupted' alarm. Follow the guide to check firstly.

2. If the alarm is not cleared, we need to check the VRM status via PuTTY to log in to the VRM node and change to the root user.


l Use the command 'service had query' to check the VRM status.




l Use the command 'netstat–anp | grep 7500' to check the port status.




l Use the command 'iptables-S' to check the port rules which have lost or not.




3. Log in to the CNA node via PuTTY to check the host status also.

l Checking the alarm list CNA node network status between other CNA node and VRM node. When you run the ping test and it fails, you need to check the E9000 switch board.

l Use the command 'ssh –v ‘VRM float ip address’ –p 7500' to check the port status on CNA host.
