6.0 HP X9720 Network Storage System Administrator Guide (AW549-96034, December 2011)

Manual upgrade procedure

The manual upgrade process requires external storage that will be used to save the cluster

configuration. Each server must be able to access this media directly, not through a network, as

the network configuration is part of the saved configuration. HP recommends that you use a USB

stick or DVD.

NOTE: Be sure to read all instructions before starting the upgrade procedure.

To determine which node is hosting the agile management console configuration, run the ibrix_fm

-i command.

Preparing for the upgrade

To prepare for the upgrade, complete the following steps:

1. Ensure that all nodes are up and running. To determine the status of your cluster nodes, check

the dashboard on the GUI or use the ibrix_health command.

2. Verify that ssh shared keys have been set up. To do this, run the following command on the

node hosting the active instance of the agile management console:

ssh <server_name>

Repeat this command for each node in the cluster.

3. Note any custom tuning parameters, such as file system mount options. When the upgrade is

complete, you can reapply the parameters.

4. Stop any active Remote Replication, data tiering, or Rebalancer tasks running on the cluster.

(Use ibrix_task -l to list active tasks.) When the upgrade is complete, you can start the

tasks again.

5. The 6.0 release requires that nodes hosting the agile management be registered on the cluster

network. Run the following command to verify that nodes hosting the agile management

console have IP addresses on the cluster network:

ibrix_fm -f

If a node is configured on the user network, see “Node is not registered with the cluster network

” (page 93) for a workaround.

6. Stop all client I/O to the cluster or file systems. On the Linux client, use lsof </mountpoint>

to show open files belonging to active processes.

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
