PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function (for Solaris(TM) Operating Environment)

3.6 /etc/opt/FJSVmpnet/conf/hostname

The IPv4 virtual interfaces to be associated with the MPNET interface configured in "/etc/opt/FJSVmpnet/conf/hosts" file are defined. This specification can be omitted. This configuration is effective, when two or more logical IPv4 addresses are required (e.g. when using destination/source IP address distribution method of Multilink Ethernet method etc.).

The following configuration samples are provided in this file. Copy the line to be used from sample to specify the configuration.

The form of the entry is shown below.

Each parameter is explained as follows.

interface-name(VIF)

The virtual interface name over the MPNET interface of MPNET is specified.

The virtual interface name is expressed by adding ":" and instance number (number of 1-255) to the logical interface name that is specified in the "/etc/opt/FJSVmpnet/conf/config" file.

hostname

This indicates the IPv4 address or the host name that is specified in the /etc/inet/hosts file.

The configuration example is shown in the following.

• This configuration enables activating and deactivating the TCP/IP interface using with the mpnet_ifinit or the mpnet_ifconfig command.
• To specify the hostname, define the IP address in the /etc/inet/hosts file, and define the net mask value in /etc/inet/netmasks file if necessary. Refer to the Solaris OS manual for setting the IP address and the net mask value.
• When using cluster system, IP address takeover by the logical IP address is not supported. When using IP address takeover, it is necessary to use the takeover that used the IPv4 address of the MPNET interface.
