Infortrend RAID Controller Manual

Power off controller 2.
Starting the Redundant Controllers
Power on all hard drives and the two
controllers. The message "RC (redundant
controller) connecting... to cancel"
will appear on the LCD display of the two
controllers. After a few seconds, the
Primary controller will startup with the
model number and firmware version
displayed on the LCD, while the
Secondary controller will display the
message "RC Standing By.. to
Cancel" on its LCD. A few seconds later,
the LCD display on the Secondary
controller will be similar to the LCD
display on the Primary controller. The
upper right corner of LCD will then be
displaying a “P” or ”S,” meaning
“Primary” or “Secondary” respectively.
During normal operation, the controllers continuously monitor each
other. Each controller is always ready to take over for the other
controller in an unlikely event of a controller failure.
The Primary and Secondary controllers synchronize each other’s
configurations at frequent intervals through the communications
channel(s). Write-back caching will be disabled on the 3102 series if
the connection between controllers is made by a redundant controller
cable without using channel 0 as the synchronized cache channel.
