IP Availability Manager automatically creates CardRedundancyGroups during discovery for Cisco devices that support the CISCO-STACK-MIB. Each such group consists of two cards. You can view the card redundancy groups and their members by using the Domain Manager Administration Console.
In addition, you can create redundancy groups for cards that do not support the CISCO-STACK-MIB. The process for manually creating a card redundancy group is similar to that for creating a system redundancy group, described in the following section. First, create an instance of the CardRedundancyGroup class and then insert the cards that participate in the redundancy group into the ComposedOf relationship.
