The CIP configuration file is stored in /etc/cip.cf on each node in the cluster. Normally, you can use the GUI to create this file during cluster configuration time. However, there may be times when you wish to manually edit this file.
The format of a CIP configuration file entry is as follows:
cfname CIP_Interface_Info [ CIP_Interface_Info...] [IPv6]
cfname tells what node the configuration information is for.
CIP_Interface_Info gives information needed to configure a single CIP interface.
Normally, the configuration information of all the CIP interfaces on all the nodes is contained in the cip.cf configuration file.
For IPv4, specify CIP_Interface_Info with the following format:
IPv4-Address[:netmask:<Netmask>]Specify it without any spaces even around colons.
For IPv4-Address, specify as a number in Internet standard dotted-decimal notation or as the Host name. When specifying with the Host name, it needs to be defined in /etc/hosts.
For <Netmask>, specify the netmask value to be set to the IP address as a number in Internet standard dotted-decimal notation.
For IPv6, specify CIP_Interface_Info with the following format:
Hostname:"["IPv6-Address/prefix_length"]"
Specify it without any spaces around colons, slashes, and inside of each brackets "[", "]".
For Hostname, describe the Host name to specify the cip address.
For IPv6-Address and prefix_length, specify the IPv6 address and the prefix length denoted as a hexadecimal code which is separated by Internet standard colons.
When using the IPv6 address, specify "IPv6" in the end of the line.
For example, the CIP configuration done in Section "1.1.5 Example of creating a cluster " would produce the following CIP configuration file:
fuji2 fuji2RMS:netmask:255.255.255.0 fuji3 fuji3RMS:netmask:255.255.255.0
Although not shown in this example, the CIP syntax does allow multiple CIP interfaces for a node to be defined on a single line. The cip.cf manual page has more details about the cip.cf file.
If you make changes to the cip.cf file by hand, you should be sure that the file exists on all the nodes, and all the nodes are specified in the file. Be sure to update all the nodes in the cluster with the new file. Changes to the CIP configuration file will not take effect until CIP is stopped and restarted.
After stopping all applications that use CIP, restart CIP by stopping and starting CF.
For instructions on starting and stopping CF, see Section "4.6 Starting and stopping CF".
