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."

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.

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

mark2Operation Procedure:

mark3If the OPERATING node is [HOST-primecl01]

  1. Setting up the system

    1. Define the IP address and Host name in /etc/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. Configure physical interface definition file as follows.

      • RHEL

        Contents of /etc/sysconfig/network-scripts/ifcfg-eth0

        DEVICE=eth0
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
BROADCAST=10.34.214.255
IPADDR=10.34.214.181
NETMASK=255.255.255.0
NETWORK=10.34.214.0
ONBOOT=yes
TYPE=Ethernet

        Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

        DEVICE=eth1
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=no
TYPE=Ethernet

        If you specify "HWADDR=XX:XX:XX:XX:XX:XX" in the setting for the physical interfaces bundled by GLS (/etc/sysconfig/network-scripts/ifcfg-ethX file), add the "HOTPLUG=no" setting.

      • SLES9

        [primary(eth0)]

        /etc/sysconfig/network/ifcfg-eth-id-XX:XX:XX:XX:XX:XX

        BOOTPROTO='static'
BROADCAST='10.34.214.255'
IPADDR='10.34.214.181'
NETMASK='255.255.255.0'
NETWORK='10.34.214.0'
STARTMODE='onboot'
UNIQUE='XXXXXXXXXXXXXXXX'
_nm_name='bus-pci-XXXX:XX:XX.X'

        [secondary(eth1)]

        /etc/sysconfig/network/ifcfg-eth-id-XX:XX:XX:XX:XX:XX

        BOOTPROTO='static'
STARTMODE='onboot'
UNIQUE='XXXXXXXXXXXXXXXX'
_nm_name='bus-pci-XXXX:XX:XX.X'

        - Edit the setup file (/etc/sysconfig/network/ifcfg-eth-id-XX:XX:XX:XX:XX:XX) that is corresponding to the MAC address "XX:XX:XX:XX:XX:XX" of physical interfaces for GLS. Do not create the configuration file of /etc/sysconfig/network/ifcfg-ethX.

        - The "UNIQUE=" and "_nm_name=" values are automatically set in the setup file. Users are not supposed to change the values.

    3. When the system is RHEL, on the /etc/sysconfig/network file, define a statement which enables the network configuration.

      NETWORKING=yes
NETWORKING_IPV6=no

  2. Rebooting

    Run the following command and reboot the system. After rebooting the system, verify eth0 is enabled using "ifconfig" command.

    # /sbin/shutdown -r now

  3. Setting a subnet mask

    For the underlined parameter, specify the network address and the subnet mask of the virtual interface.

    # /opt/FJSVhanet/usr/sbin/hanetmask create -i 10.34.214.0 -m 255.255.255.0

    Check that the facility has been set up correctly.

    # /opt/FJSVhanet/usr/sbin/hanetmask print

    For details on the subnet mask value, see "hanetmask command" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide : Redundant Line Control Function."

  4. 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 eth0,eth1

    Check that the virtual interface has been set up correctly.

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

  5. 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

  6. Setting up the Standby patrol monitoring function

    # /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m p -t sha0

    Check that the facility has been set up correctly.

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

  7. 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

mark3If the STANDBY node is [HOST-primecl02]

  1. Setting up the system

    1. Define the IP address and Host name in /etc/hosts file. Defined content is same as HOST-primecl01.

    2. Configure physical interface definition file as follows.

mark2Post-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 "Setting Up Gls Resources" and "Setting Up Cluster Applications."

You also need to reboot the system after registering the cluster application. Then, start RMS and check the RMS tree to confirm whether the Gls resources are displayed correctly. For details, see "RMS Tree."

The Gls resource name is displayed as GlsX (X is integer).

For information on GLS (redundant line control function) and other operation modes, see "Appendix B Examples of Setting Up" in the "PRIMECLUSTER Global Link Services Configuration and Administration Guide : Redundant Line Control Function."
