Configuring Automated Failover; Example Configuration; Specifying Vifs In The Client Configuration - HP IBRIX 9300 Administrator's Manual

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
-----------
ib50-81
ib50-82
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.
9000 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.)

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/SMB. Specify the VIF IP address of the servers (for example, bond0:1) to establish connection.
You can also configure DNS round robin to ensure NFS or SMB client-to-server distribution. In both
cases, the NFS/SMB clients will cache the initial IP they used to connect to the respective share,
usually until the next reboot.
FTP. When you add an FTP share on the Add FTP Shares dialog box or with the ibrix_ftpshare
command, specify the VIF as the IP address that clients should use to access the share.
HTTP. When you create a virtual host on the Create Vhost dialog box or with the
ibrix_httpvhost command, specify the VIF as the IP address that clients should use to access
shares associated with the Vhost.
9000 clients. Use the following command to prefer the appropriate user network. Execute the
command once for each destination host that the client should contact using the specified interface.
ibrix_client -n -h SRCHOST -A DESTNOST/IFNAME
For example:
ibrix_client -n -h client12.mycompany.com -A ib50-81.mycompany.com/bond1
