When generated the attribute files contain some information that is unique to the system on which it was generated. Because of this some of the parameter values must be modified before it can be used to generate nodes in a new LifeKeeper cluster. The tables below list the parameters, a short description of the parameter and a notation on if a change to the generated parameter value is required.

Parameter
Description
Change Required
node name Text string containing the name of new cluster node. The string starts with a null value [‘’]. Required
priority Communication path priority
baudrate Baud rate for the TTY communication path connection (not used for tcp communication paths).
remoteaddress IP address of the remote node. TCP communication paths have 2 end points, the local node and the remote node. This parameter contains the IP address of the remote node. This parameter along with the Ipaddress parameter define the communication path end points. Required
Device The device used for tty communication paths. Required
Remote Name of the remote node in the LifeKeeper cluster. Required
Type Type of communication path connection TTY/TCP
Ipaddress IP address of the local node. TCP communication paths have 2 end points, the local node and the remote node. This parameter contains the IP address of the local node. This parameter along with the remoteaddress parameter define the communication path end points. Required

*This parameter is not required if the tag names are not changed.

Parameters in the resource attribute file: Instance section

The main parameter list for resource instances for a LifeKeeper hierarchy. The parameters are broken down into those that are common to all LifeKeeper resource types and those specific to a LifeKeeper resource instance type.

Parameters in the lkinstall attribute file

Edit the attribute file under the LifeKeeper installation cookbook that was created in the preparation step to define the license information.

Example:
default[node][‘license’] = [‘example1.lic’,’example2.lic’]

  • node: Specify the node name on which the lifeKeeper license will be installed.
  • license: Specify license file(s).
  • example1.lic, example2… A comma separated list of license files.

This completes the description of the all the parameters in the attribute files.
