“fmadm failed to connect to fmd: RPC program not registered” Error

If you have been having trouble with the “fmadm failed to connect to fmd: rpc program not registered” error message, you have come to the right place.

According to our experts, this error usually indicates a communication issue between the Fault Management Architecture Device Manager (fmadm) tool and the Fault Management Daemon (fmd) service.

Specifically, the error suggests that the fmd service is not registered correctly with the host machine’s RPC (Remote Procedure Call) system.

Common Causes of the Error

1. fmd Service Not Running

   The most frequent cause is that the fmd service is not running or has failed to start.
2. RPC Daemon Issues

   The RPC service (rpcbind) may not be functioning properly or might have failed to register the fmd service.
3. System Misconfiguration

   A misconfiguration might prevent fmd from communicating with fmadm through RPC.
4. Corrupted Fault Management Daemon Files

   Corruption in the fmd configuration or data files could prevent proper registration with RPC.
5. Operating System Updates

   After OS updates or patches, services like fmd might not restart correctly, leading to registration failures.

Steps to Resolve the Error

1. First, use the svcs command to verify the status of fmd:

   svcs fmd

   If the output indicates that the service is offline or in maintenance mode, restart it:

   svcadm restart fmd

   Then, confirm the service is running:

   svcs fmd
2. Next, check if rpcbind is running:

   svcs rpcbind

   If it is not active, restart it:

   svcadm restart rpcbind

   Also, ensure fmd is registered with RPC:

   rpcinfo | grep fmd

   If fmd is missing, it indicates a registration issue.
3. Restart both services sequentially:

   svcadm restart rpcbind
svcadm restart fmd


   Test if fmadm is now functioning with this command:

   fmadm faulty
4. Next, check System Logs for errors. We need to inspect the logs for information on why fmd is failing:

   tail -f /var/adm/messages

   Look for error messages related to fmd or rpcbind for further diagnosis.
5. Now, heck the fmd configuration files, typically located in `/etc/fm`.

   If corruption is suspected, restore the files from a backup or attempt to repair them.
6. If restarting the services does not work, a system reboot may help reset dependencies and resolve the issue.
7. If the error appeared after a system update, check if the version of Solaris we are using has known bugs or issues. Also, verify if a specific patch or rollback is needed.
8. If fmd has crashed, core dumps may provide insight. To analyze the crash, look for core dumps in the system log directory or the configured dump location.
