Removing HA

Removing HA involves removing both software and hardware. Simply disabling the HA configuration is insufficient and is only one part of the process. Because there is more than one Screen that has the same IP address on the network, simply disabling HA would leave two or more HA Screens on the network that are trying to route the same traffic, which would disrupt the network traffic through the Screens.

Remove the HA hosts one at a time to reduce the chances of disrupting the network. Remove the passive HA host or hosts first to avoid losing connections.

If you must remove the active HA host, use the following command on both the active HA host that you want to remove and on the passive HA host that will become the active HA host. This will help you to find out whether any connections will be lost.

• For local administration:

  # ssadm lib/statetables

• For remote administration:

  # ssadm -r Screen_Name lib/statetables

If the state tables are in an acceptable level of synchronization, you can proceed to remove the active HA host.
