If the
fi
rmware version on the two controllers is not the same, the following prompt is displayed in the
controller LCD panel:
CLONE FIRMWARE ? ‘<‘ = NO, ‘>' = YES
If
>
is pressed or a response is not made to the prompt within 60 seconds, the following messages are
displayed on the LCD panel while
fi
rmware is copied from the active controller to the standby controller
and the standby controller is automatically restarted:
ROM CLONING STARTED
ARRAY CONTROLLER RESTARTING
STARTUP COMPLETE
The two controllers should now operate in redundant mode.
NOTE:
There is the possibility that a speci
fi
c version of
fi
rmware may not be compatible with certain hardware
revisions of a controller. In this scenario, the
fi
rmware on the two controllers is compared, and the version
that is compatible with both controllers is copied to the controller with the incompatible
fi
rmware version.
However, if the controller that is updated is already operating and processing I/O, it is not reset. The
MSA does not enter redundant operation and an appropriate message is shown on the display. After the
MSA has been shut down and powered back on, the controllers are then be able to enter redundant
operation. On a subsequent power cycle, both controllers enter redundant mode.
Recovering corrupted
fi
rmware
If the controller detects a
fi
rmware corruption, the following message is displayed on the LCD panel:
ERROR: ROM CORRUPT
SEND IMG VIA XMODEM
To recover the controller, you must obtain a current
fi
rmware image and send it to the controller using a
serial connection.
1.
Go to the MSA website and obtain the latest controller
fi
rmware.
NOTE:
If you are not yet registered, select the option to receive e-mail noti
fi
cations, advisories, and
support alerts about MSA system hardware,
fi
rmware, drivers, and software components.
This alert noti
fi
cation system is a one-way broadcasting method used to distribute important
notices about HP products. Information about your MSA is not requested when subscribing
to this service.
2.
Establish a serial connection to the affected controller:
• Use the custom CLI con
fi
guration cable shipped with the MSA.
• Use a terminal emulator program that supports the Xmodem protocol, such as HyperTerminal.
• Use the following emulator connection settings:
• Bits per second: 19200
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
A blank emulator window is displayed—no CLI prompt is displayed.
3.
Using the emulator transfer (or send
fi
le) command, send the
fi
rmware to the controller.
