Major Subsystem Components
practice the steps listed above. You can access array
information even without a password.
How to use the button?
After the subsystem is powered down, you can use a straighten paper-clip
to press the button. Press and hold the button while powering on the
subsystem, and wait for the associated LED and system Ready LED to light
up. The “
Restore Def.
” LED indicates successful restoration of firmware
defaults.
With redundant RAID controllers, the procedure can be tricky:
Step 1. Remove one controller 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. Power down, and remove the controller you previously
restored its defaults.
Step 3. Install the controller you have not configured, and repeat
the restoration process.
Step 4. When completed with restoring defaults on both controllers,
power down, install both controllers, and power on.
