Pause and Resume Heartbeats from the Virtual Standby Server

Virtual Standby 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, Virtual Standby 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.
• CA ARCserve Central Virtual Standby does not power on recover point snapshots while the heartbeat is in a paused state.
• When you upgrade CA ARCserve D2D installations on source nodes, CA ARCserve Central Virtual Standby 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.

Note: Optionally, you can pause or resume heartbeats from the Virtual Standby Summary screen on the node. For more information, see Pause and Resume Heartbeats from the Nodes.
