Tasks Tab

Tasks are a generalization and extension of the start, stop, and monitor scripts. Task types are determined by

when the tasks run, and include the following:

 Network Configuration – This is the first type of task that runs when applications start and is intended

to launch dnscmd or DNSUpdate. The task can launch a batch script containing multiple dnscmd

commands. Network Configuration tasks are the only types of task that can vary between Primary and

Secondary servers.

 Pre/Post Start – These tasks run before and after services start on the active server.

 Pre/Post Stop – These tasks run before and after services stop on the active server.

 Pre/Post Shadow – These tasks run before and after Data Rollback Module creates a shadow copy on the

active server.

 Rule Action – Configure these tasks to run in response to a triggered rule or when a service fails its check.

You can define and implement tasks at the command line, such as launching a batch-script. Examples of

built-in tasks include monitoring a protected service state on the active and passive servers.

vCenter Server Heartbeat can use plug-ins to define and implement tasks. An example of a plug-in-defined

task is the discovery of protected data and services for a particular application.

Click Application on the left navigation pane, and click the Tasks tab.
