6.3 HP StoreAll Storage Installation Guide (TA768-96085, April 2013)

Configuring backup servers
The network VIFs in the cluster are configured in backup pairs. If this step was not done when
your cluster was installed, assign backup servers for the bond0:1 interface. For example, node1
is the backup for node2, and node2 is the backup for node1.
1. Add the VIF:
# ibrix_nic –a -n bond0:2 –h node1,node2,node3,node4
2. Set up a backup server for each VIF:
# ibrix_nic –b –H node1/bond0:1,node2/bond0:2
# ibrix_nic –b –H node2/bond0:1,node1/bond0:2
# ibrix_nic –b –H node3/bond0:1,node4/bond0:2
# ibrix_nic –b –H node4/bond0:1,node3/bond0:2
Configuring NIC failover
NIC monitoring should be configured on VIFs that will be used by NFS, SMB, FTP, or HTTP.
IMPORTANT: When configuring NIC monitoring, use the same backup pairs that you used when
configuring standby servers.
For example:
# ibric_nic –m -h node1 -A node2/bond0:1
# ibric_nic –m -h node2 -A node1/bond0:1
# ibric_nic –m -h node3 -A node4/bond0:1
# ibric_nic –m -h node4 -A node3/bond0:1
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, SMB, FTP, and HTTP clients can connect to bond0:1
on either host. If necessary, the selected server will fail over to bond0:2 on the opposite host.
StoreAll 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.)
