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.
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:
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 Fusion Manager 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 Fusion Manager does not automatically query the node. If the VIF will be
used only as a standby network interface in an automated failover setup, the Fusion Manager 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 “Setting network interface
options in the configuration database” (page 122)). The Fusion Manager does not require a MAC
address for a VIF.
If you created a user network interface for StoreAll client traffic, you will need to prefer the network
for the StoreAll clients that will use the network (see “Preferring network interfaces” (page 122)).
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.
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:
ibrix_nic -c -n eth3 -h s4.hp.com -M 255.255.0.0 -B 10.0.0.4
Preferring network interfaces
After creating a user network interface for file serving nodes or StoreAll 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 SMB clients, because they can select the correct user network interface at mount time.)
A network interface preference is executed immediately on file serving nodes. For StoreAll clients,
the preference intention is stored on the Fusion Manager. When StoreAll software services start
on a client, the client queries the Fusion Manager for the network interface that has been preferred
for it and then begins to use that interface. If the services are already running on StoreAll clients
