6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

ibrix_hostgroup -n -g HOSTGROUP -A DESTHOST/IFNAME
The destination host (DESTHOST) cannot be a host group. For example, to prefer network interface
eth3 for traffic from all StoreAll clients (the clients host group) to file serving node s2.hp.com:
ibrix_hostgroup -n -g clients -A s2.hp.com/eth3
Unpreferring network interfaces
To return file serving nodes or StoreAll clients to the cluster interface, unprefer their preferred
network interface. The first command unprefers a network interface for a file serving node; the
second command unprefers a network interface for a client.
ibrix_server -n -h SRCHOST -D DESTHOST
ibrix_client -n -h SRCHOST -D DESTHOST
To unprefer a network interface for a host group, use the following command:
ibrix_client -n -g HOSTGROUP -A DESTHOST
Making network changes
This section describes how to change IP addresses, change the cluster interface, manage routing
table entries, and delete a network interface.
Changing the IP address for a Linux StoreAll client
After changing the IP address for a Linux StoreAll client, you must update the StoreAll software
configuration with the new information to ensure that the Fusion Manager can communicate with
the client. Use the following procedure:
1. Unmount the file system from the client.
2. Change the client’s IP address.
3. Reboot the client or restart the network interface card.
4. Delete the old IP address from the configuration database:
ibrix_client -d -h CLIENT
5. Re-register the client with the Fusion Manager:
register_client -p console_IPAddress -c clusterIF -n ClientName
6. Remount the file system on the client.
Changing the IP address for the cluster interface on a dedicated management console
You must change the IP address for the cluster interface on both the file serving nodes and the
management console.
1. If High Availability is enabled, disable it by executing ibrix_server -m -U.
2. Unmount the file system from all file serving nodes, and reboot.
3. On each file serving node, locally change the IP address of the cluster interface.
4. Change the IP address of the cluster interface for each file serving node:
<installdirectory>/bin/ibrix_nic -c -n IFNAME -h HOSTNAME [-I IPADDR]
5. Remount the file system.
6. Re-enable High Availability if necessary by executing ibrix_server -m.
