clients when you prefer a network interface, you can force clients to query the management console
by executing the command ibrix_lwhost --a on the client or by rebooting the client.
Preferring a network interface for a file serving node or Linux X9000 client
The first command prefers a network interface for a File Server Node; the second command prefers
a network interface for a client.
<installdirectory>/bin/ibrix_server -n -h SRCHOST -A DESTHOST/IFNAME
<installdirectory>/bin/ibrix_client -n -h SRCHOST -A DESTHOST/IFNAME
Execute this command once for each destination host that the file serving node or X9000 client
should contact using the specified network interface (IFNAME). For example, to prefer network
interface eth3 for traffic from file serving node s1.hp.com to file serving node s2.hp.com:
<installdirectory>/bin/ibrix_server -n -h s1.hp.com -A s2.hp.com/eth3
Preferring a network interface for a hostgroup
You can prefer an interface for multiple X9000 clients at one time by specifying a hostgroup. To
prefer a user network interface for all X9000 clients, specify the clients hostgroup. After preferring
a network interface for a hostgroup, you can locally override the preference on individual X9000
clients with the command ibrix_lwhost.
To prefer a network interface for a hostgroup, use the following command:
<installdirectory>/bin/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 X9000 clients (the clients hostgroup) to file serving node s2.hp.com:
<installdirectory>/bin/ibrix_hostgroup -n -g clients -A s2.hp.com/eth3
Unpreferring network interfaces
To return file serving nodes or X9000 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.
<installdirectory>/bin/ibrix_server -n -h SRCHOST -D DESTHOST
<installdirectory>/bin/ibrix_client -n -h SRCHOST -D DESTHOST
To unprefer a network interface for a hostgroup, use the following command:
<installdirectory>/bin/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 X9000 client
After changing the IP address for a Linux X9000 client, you must update the X9000 Software
configuration with the new information to ensure that the management console 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:
<installdirectory>/bin/ibrix_client -d -h CLIENT
5. Re-register the client with the management console:
<installdirectory>/bin/register_client -p console_IPAddress -c clusterIF –n ClientName
6. Remount the file system on the client.
