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

3.4 /etc/opt/FJSVmpnet/conf/hosts

The IPv4 interface that uses TCP/IP is specified. This configuration can be omitted if the interface that specified in the "config" and "parameters" file is used only by an FNA or SNA connection.

• This configuration allows you to activate and deactivate the TCP/IP interface using with the mpnet_ifinit or mpnet_ifconfig command.
• Please do not specify the hostname.mpnetX in the /etc directory when you do this configuration. In the Multipath function, the interface set in /etc/opt/FJSVmpnet/conf/hosts file corresponds to "hostname.interface".
• To specify the hostname, define the IP address in the /etc/inet/hosts file, and define the net mask value in /etc/inet/netmasks, if necessary. Refer to the Solaris OS manual for setting IP address and the netmask value.
• When using a TCP/IP interface for the cluster system, it is necessary to set up this configuration for the online node and the standby node. Moreover, when using IP address takeover, it is necessary to set up the IP address taken over in the /etc/inet/hosts file of each node.
• IPv4 tunnel and IPv6 tunnel are not supported by this product.
• The trailer protocol is not supported by this product.

The following configuration samples are provided in this file. Copy the line to be used from the sample to define the configuration for the communication type.
