Troubleshoot NSX Manager Cluster

You must configure a three-node NSX Manager cluster and only one of the nodes can fail at any given time for the cluster to self-heal.

For an NSX Manager cluster to self-recover from a node failure, the majority of nodes must not have failed (the number of active nodes must be greater than the failed nodes) otherwise the entire cluster becomes unavailable. It means that all write operations are blocked, all clustering related API/CLIs fail. However, local API/CLI commands continue to work.

NSX Manager logs are written into /var/log/syslog, directory.

Admin CLI

To activate Admin CLI, log in as an admin to a NSX Manager. But if you login as root, you can run singleton admin CLI directly from the root shell using the su admin –c <cmd-to-run> command. You can switch on interactive mode of admin CLI using the su admin command and then run admin commands.
