Becoming an Inactive Member
To become an inactive member of the cluster, disable clustering on the unit while leaving the clustering
configuration intact.
Note
When an ASA becomes inactive (either manually or through a health check failure), all data interfaces
are shut down; only the management-only interface can send and receive traffic. To resume traffic flow,
re-enable clustering; or you can remove the unit altogether from the cluster. See the
Cluster" section on page
received from the cluster IP pool. However if you reload, and the unit is still inactive in the cluster, the
management interface is not accessible (because it then uses the Main IP address, which is the same as
the master unit). You must use the console port for any further configuration.

already in the System configuration mode, enter the changeto system command.
Purpose

Disables clustering. If this unit was the master unit, a new master
election takes place, and a different member becomes the master
