7. On all nodes hosting the passive management console, place the management console into

maintenance mode:

<ibrixhome>/bin/ibrix_fm –m maintenance

8. On the active management console node, disable automated failover on all file serving nodes:

<ibrixhome>/bin/ibrix_server -m -U

9. Run the following command to verify that automated failover is off. In the output, the HA column

should display off.

<ibrixhome>/bin/ibrix_server -l

10. Unmount file systems on Linux X9000 clients.

11. Stop the CIFS, NFS and NDMP services on all nodes. Run the following commands on the

node hosting the active management console:

ibrix_server -s -t cifs -c stop

ibrix_server -s -t nfs -c stop

ibrix_server -s -t ndmp -c stop

If you are using CIFS, 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 necessary, use the following command to stop NFS services:

/etc/init.d/nfs stop

Use kill -9 to stop any NFS processes that are still running.

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.

12. Unmount each file system manually:

ibrix_umount -f FSNAME

Wait up to 15 minutes for the file systems to unmount.

Troubleshoot any issues with unmounting file systems before proceeding with the upgrade.

See “File system unmount issues” (page 93).

Saving the node configuration

Complete the following steps on each node, starting with the node hosting the active management

console:

1. Verify that the fusionmanager and ibrix_server services are running. The following

commands should report that the services are running.

/etc/init.d/ibrix_fusionmanager status

/etc/init.d/ibrix_server status

2. Run /usr/local/ibrix/setup/save_cluster_config. This script creates a tgz file

named <hostname>_cluster_config.tgz, which contains a backup of the node

configuration.

3. Save the <hostname>_cluster_config.tgz file, which is located in /tmp, to the external

storage media.
