PRIMECLUSTER Installation and Administration Guide 4.3

L.3.4 Changing the IP Address of GLS

Change the IP address of GLS. Change the settings on all the nodes.

See

For details on the settings, see "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function."

Note

The procedure depends on the data communication mode. The following procedure is for changing the IP address within the same network as the configuration using the NIC switching mode.

1. Delete all settings for the takeover virtual Interface.

   # /opt/FJSVhanet/usr/sbin/hanethvrsc delete -n all

2. Stop the HUB monitoring function.

   # /opt/FJSVhanet/usr/sbin/hanetpoll off

3. Modify the ifcfg-eth0 file to change the IP address of the primary physical interface.

   For [primecl03]

   [Before change]

   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

   [After change]

   DEVICE=eth0
   BOOTPROTO=static
   HWADDR=XX:XX:XX:XX:XX:XX
   HOTPLUG=no
   BROADCAST=10.34.214.255
   IPADDR=10.34.214.191
   NETMASK=255.255.255.0
   NETWORK=10.34.214.0
   ONBOOT=yes
   TYPE=Ethernet

   For [primecl04]

   [Before change]

   DEVICE=eth0
   BOOTPROTO=static
   HWADDR=XX:XX:XX:XX:XX:XX
   HOTPLUG=no
   BROADCAST=10.34.214.255
   IPADDR=10.34.214.182
   NETMASK=255.255.255.0
   NETWORK=10.34.214.0
   ONBOOT=yes
   TYPE=Ethernet

   [After change]

   DEVICE=eth0
   BOOTPROTO=static
   HWADDR=XX:XX:XX:XX:XX:XX
   HOTPLUG=no
   BROADCAST=10.34.214.255
   IPADDR=10.34.214.192
   NETMASK=255.255.255.0
   NETWORK=10.34.214.0
   ONBOOT=yes
   TYPE=Ethernet

4. Change the IP address of the virtual interface.

   For [primecl03]

   # /opt/FJSVhanet/usr/sbin/hanetconfig modify -n sha0 -i 10.34.214.195 -e 10.34.214.191

   For [primecl04]

   # /opt/FJSVhanet/usr/sbin/hanetconfig modify -n sha0 -i 10.34.214.195 -e 10.34.214.192

5. Reregister the settings of the takeover virtual Interface.

   # /opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0

6. In order to let the IP address change take effect, restart all the nodes. If you plan to do "L.3.5 Restoring the GDS Configuration Information" or "L.3.7 Setting Up System Disk Mirroring," this restarting is not necessary.

See

For changing the IP address to a different network, the subnet mask of the virtual interface and the monitoring IP address of the HUB monitoring function need to be changed. For details, see "PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function."
