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

3.2 /etc/opt/FJSVmpnet/conf/config

The logical device name of LAN used for the communication path that is composed by MPNET (that is, the interface to be activated) is defined in this file. The configuration of this file cannot be omitted.

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

The form of the entry is shown below.

interface-name

This indicates the interface name of MPNET.

The interface name is composed of the driver name "mpnet" in lower-case and the instance number (decimal number).
Unique values must be specified in the same configuration.

media-type

This indicates the type of the logical device of LAN used.

• ether : When you uses FastEthernet card or Gigabit Ethernet card.
• fddi : When you uses FDDI card.
• atm : When you uses ATM, and you use IPoA(RFC1157 SVC connection).
• lane : When you uses ATM, and you use LAN emulation.

lan-interface

This indicates the logical device name of LAN used.

• The FastEthernet and Gigabit Ethernet can not be used together in one MPNET interface.
• When ce driver is used, one MPNET interface must be configured with ce driver only.
• Make sure there is no double specification of the same logical device name of LAN.
• For an ATM connection, the number of logical devices (communication path) for which one MPNET interface can be specified is up to two.
• When using the ATM cards, the Permanent Virtual Circuit (PVC) feature is not supported.
• In the Multipath function, the "/etc/hostname.interface-name" file which corresponds to the logical interface which the Multipath function composes must not exist. Please delete the corresponding "/etc/hostname.interface-name" file, if it exists.

The configuration example is shown in the following:

• Example of Ethernet connection and environmental configuration

• Example of FDDI connection and environmental configuration

• Example of ATM connection and environmental configuration
