About attributes and their definitions
In addition to the attributes listed in this appendix, see the Veritas Cluster Server Agent Developer's Guide.
You can modify the values of attributes labelled user-defined from the command line or graphical user interface, or by manually modifying the main.cf configuration file. You can change the default values to better suit your environment and enhance performance.
When changing the values of attributes, be aware that VCS attributes interact with each other. After changing the value of an attribute, observe the cluster systems to confirm that unexpected behavior does not impair performance.
The values of attributes labelled system use only are set by VCS and are read-only. They contain important information about the state of the cluster.
The values labeled agent-defined are set by the corresponding agent and are also read-only.
