Troubleshooting Steps

There is a limited amount of troubleshooting that can be done when encountering NDMP type issues, other than repairing faulted hardware or fixing misconfiguration issues.

For NDMP service problems, restarting the NDMP service may help as a workaround.

Review the ZFS storage appliance version and keep it update to ensure the latest NDMP code is running.

When necessary, engage Oracle Support via a Service Request and also collect a supportbundle.

To check NDMP service log:
BUI -- Configurations > Services > NDMP > logs

To restart NDMP service:
BUI -- Configuration > Services > Restart NDMP services
