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.
