Figure 7-3: Auto-Detect Error 
 
For more information regarding the settings appropriate for your 
application, please consult your fibre channel administrator.  
 
Important: 
Saving changes made from this menu causes the system to reset the 
Fibre Channel Controller, which may result in data corruption.  TMS does 
not recommend changing the controller settings while the controller is 
actually transferring data. 
 
Note: 
Some HBAs do not support direct attach point-to-point operation.  If you 
are having trouble with a direct attach connection in point-to-point mode, 
try changing the controller to arbitrated loop mode.  Performance should 
not be noticeably impacted with this topology, and some HBAs may only 
support this mode. 
 
7.2   Configuring High Availability 
The administrator can configure the RamSan’s Fibre Channel (FC) 
controllers to back each other up in case of a failure.  There are five basic 
FC controller states.  The following list details what these states mean, 
how a controller can end up in each state, and what a controller’s options 
are from the states: 
 
Primary (Active) 
This default state is the most basic state.  In this state, the controller is 
not associated with any of the other FC controllers.  The administrator can 
modify any controller setting from this state, and the effect will be local to 
this controller.  This controller’s links are enabled and can be used to 
transmit and receive data.
