10 Maintaining the system
Shutting down the system
To shut down the system completely, first shut down the X9000 software, and then power off the
X9720 hardware.
Shutting down the X9000 Software
Use the following procedure to shut down the X9000 Software. Unless noted otherwise, run the
commands from the dedicated Management Console or from the node hosting the active agile
management console.
1. Disable HA for all file serving nodes:
ibrix_server -m -U
2. If your cluster has an agile management console configuration, place the passive management
console into maintenance mode. Run the following command on the node hosting the passive
management console:
ibrix_fm -m maintenance
3. Stop application services (CIFS, NFS, NDMP backup):
ibrix_server -s -t { cifs | nfs | ndmp } -c stop [-h SERVERLIST]
4. Unmount all file systems:
ibrix_umount -f <fs_name>
To unmount file systems from the management console GUI, select Filesystems > unmount.
5. Unmount all file systems from X9000 clients.
• On Linux X9000 clients, run the following command:
ibrix_lwumount -f <fs_name>
6. Verify that all file systems are unmounted:
ibrix_fs -l
7. Shut down file serving nodes other than the node hosting the active agile management console:
shutdown -t now “now”
8. Shut down the dedicated management console or the node hosting the active agile management
console:
shutdown -t now “now”
