Pause and Resume Heartbeat

The Arcserve UDP solution lets you pause and resume the heartbeats that are detected by the monitoring server. The heartbeat is the process where the source server and monitoring server communicate about the health of the source server. If the monitoring server does not detect a heartbeat after a specified length of time, the virtual standby feature provisions the virtual machine to function as the source node.

Examples: When to Pause or Resume Heartbeats

The following examples describe when to pause and resume heartbeats:

• Pause the heartbeat when you want to offline a node (source server) for maintenance.
• Resume the heartbeat after the maintenance tasks are complete and the node (source server) is online.

Be aware of the following behavior:

• You can pause and resume heartbeats at the group level or at the individual node level.
• You can pause and resume heartbeats for one or more nodes in one step.
• The Arcserve UDP solution does not power on recover point snapshots while the heartbeat is in a paused state.
• When you upgrade the agent installations on source nodes, Arcserve UDP pauses the heartbeat for the nodes. To help ensure that monitor servers monitor the upgraded nodes, resume the heartbeat for the nodes after you complete the upgrades on the nodes.

Follow these steps:

1. Log in to Arcserve UDP.
2. Click the resources tab.
3. From the left pane, navigate to Virtual Standby and click All Nodes.
4. If you have added any nodes, then the nodes will be displayed in the center pane.
4. Select the node that you want to pause or resume.
5. On the center pane, click Actions, Heartbeat, Pause or Resume.
6. The heartbeat of the selected node is paused or resumed.
