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.

Changing the cluster interface

If you restructure your networks, you might need to change the cluster interface. The following rules

apply when selecting a new cluster interface:

• The management console must be connected to all machines (including standby servers) that use

the cluster network interface. Each file serving node and X9000 client must be connected to the

management console by the same cluster network interface. A Gigabit (or faster) Ethernet port

must be used for the cluster interface.

• X9000 clients must have network connectivity to the file serving nodes that manage their data and

to the standbys for those servers. This traffic can use the cluster network interface or a user network

interface.
