Chapter 1: Introduction
Redundant-controller:
With redundant RAID controllers, the procedure can be more
complicated:
Step 1.
Remove controller B from the subsystem, power
down, and then power on with the “Restore Def.”
button depressed to restore the firmware defaults
on the remaining controller.
Step 2.
When the “Restore Def.” LED is lit and the “Default
Restored” firmware event appears on the LCD
screen, release the button. You may ask another
person to observe the message on the other side of
the chassis to see if the “Default Restored” event
appears.
Step 3.
Power down, install controller B to the controller A
slot, and repeat the restoration process.
Step 4.
When completing restoring defaults on both
controllers, install both controllers and then power
on.
