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
when you prefer a network interface, you can force clients to query the Fusion Manager 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 StoreAll client
The first command prefers a network interface for a File Server Node; the second command prefers
a network interface for a client.
ibrix_server -n -h SRCHOST -A DESTHOST/IFNAME
ibrix_client -n -h SRCHOST -A DESTHOST/IFNAME
Execute this command once for each destination host that the file serving node or StoreAll 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
:
ibrix_server -n -h s1.hp.com -A s2.hp.com/eth3
Preferring a network interface for a Windows StoreAll client
If multiple user network interfaces are configured on the cluster, you will need to select the preferred
interface for this client. On the Windows StoreAll client GUI, specify the interface on the Tune Host
tab, as in the following example.
