5.6 HP StorageWorks X9320 Network Storage System Administrator Guide (AW542-96006, June 2011)

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
Segment Servers
===============
SERVER_NAME BACKUP STATE HA ID GROUP
----------- ------- ------------ --- ------------------------------------ -----
ib50-81 ib50-82 Up on 132cf61a-d25b-40f8-890e-e97363ae0d0b servers
ib50-82 ib50-81 Up on 7d258451-4455-484d-bf80-75c94d17121d servers
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 clients could connect to bond1 on either host, as these clients do not support or require
NIC failover. (The following sample output shows only the relevant fields.)
[root@ib50-80 ~]# ibrix_nic -l

ib50-82 bond1:1 User Up, LinkUp 16.226.50.228 ib50-81 bond1:1
Specifying VIFs in the client configuration
When you configure your clients, you may need to specify the VIF that should be used for client
access.
NFS/CIFS. Specify the VIF IP address of the servers (for example, bond1:0) to establish connection.
You can also configure DNS round robin to ensure NFS or CIFS client-to-server distribution. In both
cases, the NFS/CIFS clients will cache the initial IP they used to connect to the respective share,
usually until the next reboot.
