Scripts are used in a high-availability configuration to perform several kinds of actions. Among the most important types of actions are the following:
Bringing a resource to an Online state
Bringing a resource to an Offline state
As an example of a script sending a resource Offline, you might think of a file system that has to be unmounted on a node where a fault occurs. An offline script would use the umount command to unmount the file system. Another script might use the mount command to mount it on a different node.
Besides such online and offline scripts, there are also pre-online and pre-offline scripts for preparing transition into the respective states, as well as a number of other scripts.
