Unpreferring Network Interfaces; Making Network Changes; Changing The Ip Address For A Linux Storeall Client - HP StoreAll 8800 Administrator's Manual

Preferring a network interface for a hostgroup
You can prefer an interface for multiple StoreAll clients at one time by specifying a hostgroup. To
prefer a user network interface for all StoreAll clients, specify the clients hostgroup. After
preferring a network interface for a hostgroup, you can locally override the preference on individual
StoreAll clients with the command ibrix_lwhost.
To prefer a network interface for a hostgroup, use the following command:
ibrix_hostgroup -n -g HOSTGROUP -A DESTHOST/IFNAME
The destination host (DESTHOST) cannot be a hostgroup. For example, to prefer network interface
eth3 for traffic from all StoreAll clients (the clients hostgroup) 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 hostgroup, 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:
