Identifying a user network interface for a file serving node

To identify a user network interface for specific file serving nodes, use the ibrix_nic command.

The interface name (IFNAME) can include only alphanumeric characters and underscores, such

as eth1.

<installdirectory>/bin/ibrix_nic -a -n IFNAME -h HOSTLIST

If you are identifying a VIF, add the VIF suffix (:nnnn) to the physical interface name. For example,

the following command identifies virtual interface eth1:1 to physical network interface eth1 on

file serving nodes s1.hp.com and s2.hp.com:

<installdirectory>/bin/ibrix_nic -a -n eth1:1 -h s1.hp.com,s2.hp.com

When you identify a user network interface for a file serving node, the management console queries

the node for its IP address, netmask, and MAC address and imports the values into the configuration

database. You can modify these values later if necessary.

If you identify a VIF, the management console does not automatically query the node. If the VIF

will be used only as a standby network interface in an automated failover setup, the management

console will query the node the first time a network is failed over to the VIF. Otherwise, you must

enter the VIF's IP address and netmask manually in the configuration database (see

interface options in the configuration database" (page

require a MAC address for a VIF.

If you created a user network interface for X9000 client traffic, you will need to prefer the network

for the X9000 clients that will use the network (see

Setting network interface options in the configuration database

To make a VIF usable, execute the following command to specify the IP address and netmask for

the VIF. You can also use this command to modify certain ifconfig options for a network.

<installdirectory>/bin/ibrix_nic -c -n IFNAME -h HOSTNAME [-I IPADDR] [-M NETMASK]

[-B BCASTADDR] [-T MTU]

For example, to set netmask 255.255.0.0 and broadcast address 10.0.0.4 for interface eth3 on

file serving node s4.hp.com:

<installdirectory>/bin/ibrix_nic -c -n eth3 -h s4.hp.com -M 255.255.0.0 -B 10.0.0.4

After creating a user network interface for file serving nodes or X9000 clients, you will need to

prefer the interface for those nodes and clients. (It is not necessary to prefer a network interface

for NFS or CIFS clients, because they can select the correct user network interface at mount time.)

When you prefer a user network interface for traffic from a source host to a destination host, traffic

in the reverse direction remains defaulted to the cluster interface.
