PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.1 (for Solaris(TM) Operating System)

3.2.2.5 System setup in NIC switching mode

When using IPv4 address:

• When using an IPv4 address, define in the /etc/inet/hosts file the host names (host names to be attached to virtual IP, monitored host names to be specified in monitoring destination information, etc.) to be specified in environment definitions of Redundant Line Control function. These host names must be specified in the /etc/inet/hosts file even if no host names but IP addresses are directly specified in environment definitions.
• When using an IPv4 address, define a configured primary physical interface to use in IPv4 before defining a virtual interface. (Check whether or not an /etc/hostname.interface file exists. If not, create it and reboot the system.)
• For Redundant Line Control function, the path information must be initialized and the routing daemon must be restarted. If path information is statically specified, the static paths must be described in /etc/gateways.

When using IPv6 address:

• If an IPv6 address is used, define the IPv6 address and a host name in /etc/inet/ipnodes file.
• When using an IPv6 address, define a configured physical interface to use in IPv6 before defining a virtual interface. (Check whether or not an /etc/hostname6.interface file exists. If not, create it and reboot the system. When creating a /etc/hostname6.interface file, make sure it is an empty file.)
• When using an IPv6 address, set an IPv6 router on a network to be connected without fail. Specify the same prefix and the same length of a prefix for an IPv6 address to be set in a Redundant Line Control function as those set in an IPv6 router.
  In addition, when you use a Solaris server as an IPv6 router, please define two or more server as an IPv6 router. When abnormalities occur in an IPv6 router, it becomes impossible to perform communication which used a site local address. Therefore, it recommends defining two or more IPv6 routers. When you define an IPv6 router as two or more servers, the prefix information on the virtual interface defined as /etc/inet/ndpd.conf should define the same value in each server.
  An example of setting a /etc/inet/ndpd.conf file when using a Solaris server as an IPv6 router is shown below. (See a Solaris manual for the detail of a /etc/inet/ndpd.conf file.)

ifdefault AdvSendAdvertisements true  # Every interface sends a router advertisement.
prefix fec0:1::0/64 hme0              # hme0 sends "Prefix fec0:1::0/64".
prefix fec0:2::0/64 hme1              # hme1 sends "Prefix fec0:2::0/64".
