The Quarantine Feature: Prohibiting Nodes From Being Managed by Cassatt

Intended for use with Cassatt Active Response Premium Edition and Data Center Edition V5.1.

This article describes the quarantine feature, when to use it, and where to find it in the Cassatt Active Response Controller.

Use cases for node quarantine

Quarantine is a feature in the Cassatt Active Response Controller that allows you to isolate and prohibit nodes from being managed by Cassatt Active Response. The two use cases for using this feature are to:

• Keep existing nodes with their IP addresses
  If you have nodes at your site that fall in the reserved IP address range for Cassatt Active Response DHCP range, and you want to maintain the IP addresses for those nodes, and the nodes' power controllers are configured for DHCP, you must quarantine the nodes to ensure Cassatt Active Response doesn't answer DHCP requests from them.
• Have a subset of blades under Cassatt management within a blade enclosure
  Not all blades in a blade enclosure have to be dedicated to Cassatt Active Response management. If you want a subset of nodes to be managed by Cassatt Active Response, you can allow Cassatt Active Response to discover all of the blades in the enclosure, and then delete and quarantine the nodes that you don't want to be managed by Cassatt Active Response.

Where to find the quarantine feature

The ability to quarantine nodes is available throughout the Cassatt Active Response Controller:

• Domain > System tab > Add Device – this is where you can proactively quarantine devices.
• Delete node – on the confirmation dialog for deleting nodes, there is a checkbox for node quarantine.
