Fast-start failover will occur if both the observer and the target standby database lose connection to the primary database for the period of time specified by the FastStartFailoverThreshold configuration property.

Fast Start Failover is a feature available through oracle dataguard broker which performs an automatic failover to the chosen standby database in case of a primary database crash. FSFO involves an OBSERVER component which runs on a different machine than that of the primary and the standby database.
But now the I cannot switch back because of fast_start failover errors. I cannot disable fast > ORA-16654: fast-start failover is

Fast-Start failover(FSFO) in Oracle 11g Dataguard Failover is a one way process where your primary database goes Fast-Start Failover: DISABLED
However, there may be situations in which you must disable fast-start failover when the primary database and the target standby database do not have a network connection, or the database on which you issued the disable fast-start failover command does not have a network connection to the primary database.
Another standby database that does not have connectivity with the primary database, fast-start failover is disabled for this database. Because fast-start failover was not disabled on the target standby database, the observer may still attempt a fast-start failover to the target standby database should conditions warrant a failover.
Question: I want to deploy fast_start failover, but I don't understand the steps for enabling fast_start failover and verifying that fast_start
