3. Assign an IP address to the bond1:1 VIFs on each node:

# ibrix_nic –c –n bond1:1 –h node1 –I 16.123.200.201 –M 255.255.255.0

# ibrix_nic –c –n bond1:1 –h node2 –I 16.123.200.202 –M 255.255.255.0

# ibrix_nic –c –n bond1:1 –h node3 –I 16.123.200.203 –M 255.255.255.0

# ibrix_nic –c –n bond1:1 –h node4 –I 16.123.200.204 –M 255.255.255.0

Configuring standby backup nodes

Assign standby backup nodes for the bond1:1 interface. The backup nodes should be configured

in pairs. For example, node1 is the backup for node2, and node2 is the backup for node1.

1. Identify the VIF:

# ibrix_nic –a -n bond1:2 –h node1,node2,node3,node4

2. Set up a standby server for each VIF:

# ibric_nic –b –H node1/bond1:1,node2/bond1:2

# ibric_nic –b –H node2/bond1:1,node1/bond1:2

# ibric_nic –b –H node3/bond1:1,node4/bond1:2

# ibric_nic –b –H node4/bond1:1,node3/bond1:2

Configuring NIC failover

NIC monitoring should be configured on VIFs that will be used by NFS, CIFS, FTP, or HTTP. Use the

same backup pairs that you used when configuring standby servers. For example:

# ibric_nic –m -h node1 -A node2/bond1:1

# ibric_nic –m -h node2 -A node1/bond1:1

# ibric_nic –m -h node3 -A node4/bond1:1

# ibric_nic –m -h node4 -A node3/bond1:1

Configuring automated failover

To enable automated failover for your file serving nodes, execute the following command:

ibrix_server —m [-h SERVERNAME]

Example configuration

This example uses two nodes, ib50-81 and ib50-82. These nodes are backups for each other,

forming a backup pair.

[root@ib50-80 ~]# ibrix_server -l

All VIFs on ib50-81 have backup (standby) VIFs on ib50-82. Similarly, all VIFs on ib50-82 have

backup (standby) VIFs on ib50-81. NFS, CIFS, FTP, and HTTP clients can connect to bond1:1 on

either host. If necessary, the selected server will fail over to bond1:2 on the opposite host. X9000
