- Tracing the Packets of a NetScaler Cluster
- Troubleshooting Common Issues
Connectivity problems. The node cannot connect to the cluster IP address. Try pinging the cluster IP address from the node that you are trying to join.
Duplicate cluster IP address. Check to see if the cluster IP address exists on some non-cluster node. If it does, create a new cluster IP address and try re-joining the cluster.
From the command line:
show ns hardware
show ns license
From the shell:
nsconmsg -g feature -d stats
View the contents of the /var/log/license.log file
If some of the cluster nodes are in this state, you must perform the force cluster synchronization operation on those nodes. For more information, see "Synchronizing Cluster Configurations".
If all cluster nodes are in this state, you must disable and then enable the cluster instance on all the cluster nodes.
To synchronize the times, you must do the following on the cluster IP address:
set ptp -state disable
Configure Network Time Protocol (NTP) for the cluster. For more information, see "Setting up Clock Synchronization".
If the NSIP address is reachable, you can SSH to the cluster IP address from the shell by executing the following command at the shell prompt:
# ssh nsroot@<cluster IP address>
Disable the cluster instance on that node (since you cannot execute commands from the NSIP of a cluster node).
Execute the commands required to recover the node.
Enable the cluster instance on that node.
disable cluster instance <clId>
rm route <network> <netmask> <gateway>
enable cluster instance <clId>
