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. This topology should
not affect performance noticeably, 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.
