10 Array controller
fi
rmware
Each array controller contains Read-Only Memory (ROM), which holds the
fi
rmware that operates the
controller. In dual-controller con
fi
gurations, the two controllers must execute the same
fi
rmware version.
Included in this section:
• Determining the currently-installed
fi
rmware version
• Updating controller
fi
rmware
• Cloning controller
fi
rmware
• Recovering corrupted
fi
rmware
NOTE:
After updating MSA controller
fi
rmware, be sure to check the status of the MSA for unexpected issues.
Verify the status of the connections, de
fi
ned pro
fi
le types, redundancy settings, and storage con
fi
guration.
Determining the currently installed
fi
rmware version
To determine the
fi
rmware version currently running on a controller, do one of the following:
•
On the MSA controller LCD panel, use the arrow keys to scroll backwards through the messages until
the
ARRAY CONTROLLER FIRMWARE VER <version>
message is displayed.
•
Each time the MSA controller is restarted, view the
fi
rst message that displays the
fi
rmware version.
•
In the CLI, use the
SHOW VERSION
command.
Updating controller
fi
rmware
Because the MSA can operate in a variety of operating system environments, several updating methods
are available. To perform an update, obtain the following items from the MSA website:
•
Controller
fi
rmware (on the
Software, Firmware & Drivers
page.)
•
Firmware updating guide (on the
Technical Documents
page.)
Cloning controller
fi
rmware
NOTE:
Cloning is possible only in dual-controller con
fi
gurations.
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 different, the array controller LCD panel prompts to clone the
fi
rmware from one controller to the other, so that they have the same version.
The determination as to which
fi
rmware version is used is based on the following criteria:
•
If the MSA is being powered up with both controllers inserted, then the most recent version of
fi
rmware
is used regardless of which controller it resides on.
•
If the MSA is already operating and an optional controller is hot-plugged, then the version of
fi
rmware
that is on the original (non-hot-plugged) controller is used regardless of its version. This ensures that
any host-initiated I/O to the controller is not interrupted.
