Pause and Resume Heartbeats from the Nodes

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.

Note: Optionally, you can pause and resume heartbeats from the Node screen on the Virtual Standby server. For more information, see Pause and Resume Heartbeats from the Virtual Standby Server.

Follow these steps:

1. Log in the Virtual Standby server.

   Click Nodes on the Navigation bar to open the Node screen.

2. From the Groups list, click All Nodes, or click the group that contains the CA ARCserve D2D node that you want to log in to.

   The nodes list displays all nodes associated with the specified group.

3. Browse to and click the node that you want pause or resume the heartbeat and click Login D2D from the pop-up menu.

5. (Optional) If you logged in to a monitoring server, expand All or Server Running from the Servers list, and click the node whose heartbeat you want to pause or resume.

6. Do one of the following:
   • If the heartbeat is running, click Pause Heartbeat to pause the heartbeat temporarily.

     Example: You want to bring the server offline to perform maintenance tasks.
