To drop companion mode, issue:
sp_companion companion_name, "drop"
Dropping companion mode is irreversible; you must reconfigure the companion servers before they will fail over in a high availability system and retain all the functionality that Sybase Failover provides. However, the companion server is still monitored by the Veritas Cluster Server Agent for Sybase. Before dropping the companion mode, you must first disable the agent to monitor Adaptive Server. Issue:
haagent -modify Sybase_resource_name Enabled 0
To drop the companion mode, issue sp_companion ... drop.
