DFS3810 KEYWORD ACTIVE OR BACKUP DOES NOT MATCH SYSTEM OR IS MISSING

Explanation
 One of the following occurred:   
The keyword indicating whether the /SWITCH SYSTEM command
is being entered on the active or the alternate (backup) system (ACTIVE/BACKUP)
does not correspond to the actual system.

The keyword ACTIVE is missing. The keyword ACTIVE must be specified
when the /SWITCH SYSTEM command is entered on the
active system.

System action
 The command is rejected.

Programmer response
 Be sure of the status (active or alternate)
of the system on which you are entering the command.
