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.
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
.
