6.1.1 GLS Setup

For information on the initial GLS setup, see "Chapter 5 Operation on Cluster System" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function" and "Chapter 7 Administration on a Cluster System" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function."

This section describes how to set up "the Single system without NIC sharing of the NIC switching mode (IPv4)" that GLS (redundant line control function) provides. This procedure is described in the example below.

Note

You can use PRIMECLUSTER "takeover network" and GLS "IP address takeover" together in a same cluster system; however, you cannot configure them on the same interface. If this occurs, communication using takeover IP addresses is disenabled.

For example, if you select hme1 as the interface when you set up the PRIMECLUSTER "takeover network," do not set hme1 in the GLS environment settings (do not specify hme1 using "-t" option of the "hanetconfig create" command).

The setup values correspond to those on the "A.7.2 GLS Setup Worksheet."

Operation Procedure:

If the OPERATING node is [HOST-primecl01]

Setting up the system

Define the IP address and Host name in /etc/inet/hosts file.

10.34.214.185   takeoverIP   # Virtual IP
10.34.214.181   primecl01    # primecl01 Physical IP
10.34.214.182   primecl02    # primecl02 Physical IP
10.34.214.188   swhub1       # primary HUB IP
10.34.214.189   swhub2       # secondary HUB IP

Configure /etc/hostname.hme0 file as follows.
Contents of /etc/hostname.hme0
```
primecl01
```

Rebooting
Run the following command and reboot the system. After rebooting the system, verify hme0 is enabled using ifconfig command.
```
# /usr/sbin/shutdown -y -i6 -g0
```
Creating of virtual interface
For the underlined parameter, specify the physical IP address of the node.
```
# /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 10.34.214.185 -e 10.34.214.181 -t hme0,hme3
```
Check that the virtual interface has been set up correctly.
```
# /opt/FJSVhanet/usr/sbin/hanetconfig print
```
Setting up the HUB monitoring function
For the underlined parameter, specify the IP addresses of the hubs to be monitored.
```
# /opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 10.34.214.188,10.34.214.189 -b off
```
Check that the facility has been set up correctly.
```
# /opt/FJSVhanet/usr/sbin/hanetpoll print
```
Setting up the Standby patrol monitoring function
For the underlined parameter, specify the MAC address using the format 02:xx:xx:xx:xx:xx. Specify the address so that the values of the two nodes are not the same.
```
# /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m p -a 02:00:00:00:00:00 -t sha0
```
Check that the facility has been set up correctly.
```
# /opt/FJSVhanet/usr/sbin/hanetconfig print
```
Creating of the takeover IP address (takeover virtual Interface)
```
# /opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
```
Check that the registration has been done correctly.
```
# /opt/FJSVhanet/usr/sbin/hanethvrsc print
```

If the STANDBY node is [HOST-primecl02]

Setting up the system
1. Define the IP address and Host name in /etc/inet/hosts file. Defined content is same as HOST-primecl01.
2. Configure /etc/hostname.hme0 file as follows.
  Contents of /etc/hostname.hme0
```
primecl02
```
Rebooting
Run the following command and reboot the system. After rebooting the system, verify hme0 is enabled using ifconfig command.
```
# /usr/sbin/shutdown -y -i6 -g0
```
Creating of virtual interface
For the underlined parameter, specify the physical IP address of the node.
```
# /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 10.34.214.185 -e 10.34.214.182 -t hme0,hme3
```
Check that the virtual interface has been set up correctly.
```
# /opt/FJSVhanet/usr/sbin/hanetconfig print
```
Setting up the HUB monitoring function
For the underlined parameter, specify the IP addresses of the hubs to be monitored.
```
# /opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 10.34.214.188,10.34.214.189 -b off
```
Check that the facility has been set up correctly.
```
# /opt/FJSVhanet/usr/sbin/hanetpoll print
```

Setting up the Standby patrol monitoring function

# /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m p -a 02:00:00:00:00:01 -t sha0

Check that the facility has been set up correctly.

# /opt/FJSVhanet/usr/sbin/hanetconfig print

Creating of the takeover IP address (takeover virtual Interface)
```
# /opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0
```
Check that the resources have been set up correctly.
```
# /opt/FJSVhanet/usr/sbin/hanethvrsc print
```

Post-setup processing

After the OPERATING and STANDBY node setup is done, create the Gls resources, and register them to the cluster application.

For details, see "6.6.1.4 Creating Gls Resources" and "6.6.2 Creating Cluster Applications."
