that controller failback is totally transparent.

   

Choose “View and Edit Peripheral Devices,” “Set Peripheral Device
Entry," then enable the "Redundant Controller" configuration.  You
will be requested to enter a value for the “Controller Unique
Identifier.”  For firmware release 3.25 and above, enter a hex
number between 0 and FFFFF.  The identifier selection box will
prompt automatically.  The value you enter MUST be different for
each controller.

The unique identifier can also be accessed from "View and Edit
Configuration Parameters" → "Controller Parameters" → "Controller
Unique ID."

Controllers running firmware version 3.14 and above supports
controller communications over Fibre loops.

There are two options with the controller communications over
Fibre loops.  Hardware configuration should be completed before
firmware setting.

Select from the main menu "View and Edit SCSI channels,"
and configure the selected FC channels into "RCCOM
(Redundant Controller Communication)" mode.  To ensure
the connection with data path redundancy, you may use
two channels as the dedicated RCC loops.  The dedicated
channels should not be attached with any other device.
