10 Maintaining the system

Shutting down the system

To shut down the system completely, first shut down the IBRIX software, and then power off the
system hardware.

Shutting down the IBRIX software

Use the following procedure to shut down the IBRIX software. Unless noted otherwise, run the
commands from the node hosting the active Fusion Manager.
1. Stop any active Remote Replication, data tiering, or rebalancer tasks. Run the following
command to list active tasks and note their task IDs:
# ibrix_task -l
Run the following command to stop each active task, specifying its task ID:
# ibrix_task -k -n TASKID
2. Disable High Availability on all cluster nodes:
ibrix_server -m -U
3. Move all passive Fusion Manager instances into nofmfailover mode:
ibrix_fm -m nofmfialover -A
4. Stop the SMB, NFS and NDMP services on all nodes. Run the following commands:
ibrix_server -s -t cifs -c stop
nl
ibrix_server -s -t nfs -c stop
nl
ibrix_server -s -t ndmp -c stop
If you are using SMB, verify that all likewise services are down on all file serving nodes:
ps –ef | grep likewise
Use kill -9 to stop any likewise services that are still running.
If you are using NFS, verify that all NFS processes are stopped:
ps –ef | grep nfs
If processes are running, use the following commands on the affected node:
# pdsh –a service nfslock stop | dshbak
nl
# pdsh –a service nfs stop | dshbak
If necessary, run the following command on all nodes to find any open file handles for the
mounted file systems:
lsof </mountpoint>
Use kill -9 to stop any processes that still have open file handles on the file systems.
5. List file systems mounted on the cluster:
# ibrix_fs –l
6. Unmount all file systems from 9000 clients:
On Linux 9000 clients, run the following command to unmount each file system:
ibrix_lwumount -f <fs_name>
On Windows 9000 clients, stop all applications accessing the file systems, and then use
the client GUI to unmount the file systems (for example, I: DRIVE). Next, go to Services
and stop the fusion service.
