PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

6.6.1.5.1 Prerequisites

This section describes the prerequisites for MAC address takeover.
MAC address takeover is enabled concurrently with takeover of an IP address. The MAC address takeover cannot be used by itself. To use MAC address takeover, you need to configure the following three files on each cluster node.

• /etc/opt/FSUNnet/mactool/macaddr.conf
• /usr/opt/reliant/etc/hvipalias
• /etc/inet/hosts

Although not mentioned in the procedure descriptions, the commands of a text editor such as vi(1) are generally used for file editing.

Using MAC address takeover

1. Edit the "/etc/opt/FSUNnet/mactool/macaddr.conf" file.

   On all cluster nodes, add the takeover MAC address entry as shown below.

   The format is "NIC MAC_address cluster."

   hme0 02:11:22:33:44:55 cluster

   For the MAC address, specify the value to be used in the Netcompo FNA-LAN.

2. Edit the "/usr/opt/reliant/etc/hvipalias" file.

   On all cluster nodes, add entries for the target nodes of MAC address takeover as shown below.

   The format is "CF_node_name takeover_network_name NIC Netmask MAC_address."

   fuji2 Ipaddress01 hme0 0xffffff00 02:11:22:33:44:55

   fuji3 Ipaddress01 hme0 0xffffff00 02:11:22:33:44:55

   Add all cluster nodes that will be using MAC address takeover. The same information must be set in all cluster nodes.

   To view more detailed information for the "/usr/opt/reliant/etc/hvipalias" file, see the comments in /usr/opt/reliant/etc/hvipalias.

3. Edit the "/etc/inet/hosts" file.

   On all cluster nodes, add the takeover network entry as shown below.

   192.168.246.100 Ipaddress01
