In the event of a failover you would manually change to the HA IP through DNS to force the users to the new system. This will not be seemless but should work. SSO relies on DNS to do most of the work according to IBM. The other issue would be if a user connects useing the IP I think the system name will need to be used unless you have both IP’s assigned to the system name in DNS. We have not tried this on our system at this time. Hope this helps.
