haconf - allow or prevent dynamic changes to the VCS configuration file

SYNOPSIS

haconf -makerw
haconf -dump [-makero]
haconf -help

AVAILABILITY

VRTSvcs

DESCRIPTION

The haconf command enables dynamic changes to a VCS cluster. This includes adding and deleting objects, adding, deleting and modifying attributes, and writing them back to disk.
The configuration file is read-only (by default) upon starting a VCS server on a system. If the VCS server exits without saving the configuration, the configuration is not stale. Use the haconf command to enable modifications to the configuration while VCS is running.

OPTIONS

-makerw	Change VCS to read-write mode, after which changes to the configuration can be made while VCS is running. The configuration must be written back to disk and made read-only by specifying the -dump and -makero options. Otherwise, when VCS stops and restarts later the configuration changes are not effective.If you define the value of BackupInterval cluster attribute, then VCS backs up the configuration files periodically as .autobackup files.
-dump [-makero]
	Write the configuration to disk. -makero changes the VCS mode to read-only.
-help	Display information about this command.

EXAMPLES

To dynamically add a new system to a group’s SystemList in the configuration, use the following commands:

     # haconf -makerw
     # hagrp -modify group1 SystemList -add sysa 1
     # haconf -dump -makero
