6.2.1 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.

Interface names listed in examples of setting up vary depending on the environment. Replace interface names according to the environment. For Solaris 11 OS, the default interface name is netX (X means the instance number).

Note

You can use PRIMECLUSTER "takeover network" and GLS "IP address takeover" together in the 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
1. 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
```
2. Setting up interface to use.
  - For Solaris 10
    Add the host names from above definitions to the /etc/hostname.hme0 file.
    Contents of /etc/hostname.hme0
```
primecl01
```
  - For Solaris 11
    Set up with the interface and the host name defined above using ipadm(1M) command.
    Interface net0 (corresponding to hme0 in the figure)
```
# /usr/sbin/ipadm create-ip net0
# /usr/sbin/ipadm create-addr -T static -a primecl01/24 net0/v4
```
3. Define the subnet masks in the /etc/inet/netmasks file.
```
10.0.0.0    255.255.255.0
```
Rebooting
Run the following command and reboot the system. After rebooting the system, verify the interface set using ifconfig command is enabled.
```
# /usr/sbin/shutdown -y -i6 -g0
```

Creating of virtual interface

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 "6.7.1.4 Creating Gls Resources" and "6.7.2 Creating Cluster Applications."
