B.3.7 Example of the Cluster system (Cascade)

This section describes an example configuration procedure of the network shown in the diagram below.

The xx, yy and zz in the figure below are assigned automatically by the automatic address configuration.

For configuring the cluster system, refer to the Cluster system manual.
In this section, description of private LAN is omitted.
The dotted line indicates that the interface is inactive.

Note

When using IPv6 address as a takeover virtual interface, it may take around 30 seconds to recover the communication after switching the node. In order to hold a communication instantly, start IPv6 routing daemon beforehand on both operating and standby nodes. For details on this issue, refer to "F.2 Troubleshooting".

[HOST-A]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/inet/hosts file.

192.168.70.1    host11  # HOST-A Physical IP (1)
192.168.71.1    host12  # HOST-A Physical IP (2)
192.168.80.1    hosta   # HOST-A Virtual IP
192.168.70.2    host21  # HOST-B Physical IP (1)
192.168.71.2    host22  # HOST-B Physical IP (2)
192.168.80.2    hostb   # HOST-B Virtual IP
192.168.70.3    host31  # HOST-C Physical IP (1)
192.168.71.3    host32  # HOST-C Physical IP (2)
192.168.80.3    hostc   # HOST-C Virtual IP
192.168.80.4    hosta1  # Takeover virtual IP

1-2) For Solaris 10
Write the hostnames defined above in /etc/hostname.fjgi0 file and /etc/hostname.fjgi1 file. If a file does not exist, create a new file.

1-2) For Solaris 11
Set the host by the interface used with the ipadm(1M) command and also by the host name defined above.

1-3) Define the subnet mask in /etc/inet/netmasks file.

192.168.70.0    255.255.255.0
192.168.71.0    255.255.255.0
192.168.80.0    255.255.255.0

1-4) Create /etc/inet/ndpd.conf file and set the followings:

ifdefault AdvSendAdvertisements true  # Every interface sends a router advertisement.
prefix fec0:1::0/64 sha0              # sha0 sends Prefix "fec0:1::0/64".

Note

In the Solaris server that runs Fast switching mode, configure two or more router as IPv6 router. If the IPv6 router breaks down, it cannot use site-local address to communicate. To prevent this, it is recommended to setup at least two IPv6 routers.
For details on /etc/inet/ndpd.conf, refer to the Solaris manual.

1-5) For Solaris 10
Create /etc/hostname6.fjgi0 and /etc/hostname6.fjgi1 files as an empty file.

[Configuration by RMS Wizard]

1) Configuration of userApplication

After completing step 4) of both HOST-B and HOST-C, connect to the administration server using RMS Wizard, then setup the cluster environment.
To create Gls resources, select the SysNode compliant with HOST-A, HOST-B, and HOST-C. Once Gls is created, register the two Gls resources on the userApplication.
When registering on the userApplication, select the SysNode compliant with HOST-A, HOST-B, and HOST-C in the order of operation node followed by standby node. Then, register the takeover address "192.168.80.4 - fec0:1::4".

2) Starting of userApplication

After completing the configuration, start the userApplication to activate the takeover virtual interface on the operation node.
