Symptoms

NetWorker Web UI (NWUI) does not start after a server reboot.

Checking the service status returned the message.

# systemctl status nwui
Unit nwui.service could not be found.

The nwui.service file is installed in the default location with the correct permissions.

The nwui.service is enabled to start automatically after a reboot.

Cause

The `nwui.service` fails to initialize because the required `/opt` file system where the NWUI is installed was not mounted at the time of the service unit startup. The `/opt` file system was mounted some time after the initialization attempt, causing the service to fail to start.

Resolution

To ensure that the `nwui.service` starts correctly after a reboot, the service unit file /opt/nwui/scripts/nwui.service must be updated to include dependencies on the required file system. The dependency should be added to the "After" directive under the [unit] section as show below:

# description: NetWorker Management Web UI Server systemd unit file.

[Unit]
Description=NetWorker Management Web UI Server
After=syslog.target network.target opt.mount 

[Service]
...
...

Because nwui.service was modified, run.

# systemctl daemon-reload

Start the service with.

# systemctl start nwui.service

Next time the server is rebooted, the nwui service will start automatically.
