NOTE:
Each time a system with two controllers is powered on or restarted, or if a second controller is
hot-plugged into a single-controller con
fi
guration, the
fi
rmware versions on the controllers are compared.
If the
fi
rmware versions on the two controllers are not the same, the controller LCD panel prompts to clone
the
fi
rmware from the controller with the latest version onto the other controller. For more information,
see the MSA1510i installation and user guide.
Verifying proper operation
After replacing the array controller, controller cache module, or cache module battery pack, verify that:
•
The controller Heartbeat LED is blinking.
•
The controller Fault LED is off.
•
No new error messages are displayed on the array controller LCD display panel.
After installing a new array controller, verify that the latest available
fi
rmware is installed. For information,
see the MSA1510i installation and user guide.
