Preferring a network interface for a host group
You can prefer an interface for multiple 9000 clients at one time by specifying a host group. To
prefer a user network interface for all 9000 clients, specify the clients host group. After preferring
a network interface for a host group, you can locally override the preference on individual 9000
clients with the command ibrix_lwhost.
To prefer a network interface for a host group, use the following command:
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 9000 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 9000 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 9000 client
After changing the IP address for a Linux 9000 client, you must update the IBRIX software
configuration with the new information to ensure that the Fusion Manager can communicate with
the client. Use the following procedure:
