Unmount all file systems on the cluster nodes:

ibrix_umount -f <fs_name>

To unmount file systems from the GUI, select Filesystems > unmount.

Verify that all file systems are unmounted:

ibrix_fs -l

If a file system fails to unmount on a particular node, continue with this procedure. The file

system will be forcibly unmounted during the node shutdown.

Shut down all IBRIX Server services and verify the operation:

# pdsh –a /etc/init.d/ibrix_server stop | dshbak

# pdsh –a /etc/init.d/ibrix_server status | dshbak

10.

Wait for the Fusion Manager to report that all file serving nodes are down:

# ibrix_server –l

1 1.

Shut down all nodes other than the node hosting the active Fusion Manager:

# pdsh -w HOSTNAME shutdown -t now "now"

For example:

# pdsh -w x850s3 shutdown -t now "now"

# pdsh -w x850s2 shutdown -t now "now"

12.

Shut down the node hosting the active agile Fusion Manager:

shutdown -t now "now"

13.

Use ping to verify that the nodes are down. For example:

# ping x850s2

PING x850s2.l3domain.l3lab.com (12.12.80.102) 56(84) bytes of data.

x850s1.l3domain.l3lab.com (12.12.82.101) icmp_seq=2 Destination Host

Unreachable

If you are unable to shut down a node cleanly, use the following command to power the node

off using the iLO interface:

# ibrix_server -P off -h HOSTNAME

14.

Shut down the Fusion Manager services and verify:

# /etc/init.d/ibrix_fusionmanager stop

# /etc/init.d/ibrix_fusionmanager status

15.

Shut down the node hosting the active Fusion Manager:

# shutdown -t now "now"
