10 Array controller firmware
Each array controller contains Read-Only Memory (ROM), which holds the firmware that operates the
controller. In dual-controller configurations, the two controllers must execute the same firmware version.
Included in this section:
• Determining the currently-installed firmware version
• Updating controller firmware
• Cloning controller firmware
• Recovering corrupted firmware
NOTE:
After updating MSA controller firmware, be sure to check the status of the MSA for unexpected issues.
Verify the status of the connections, defined profile types, redundancy settings, and storage configuration.
Determining the currently installed firmware version
To determine the firmware 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 first message that displays the firmware version.
• In the CLI, use the SHOW VERSION command.
Updating controller firmware
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 firmware (on the Software, Firmware & Drivers page.)
• Firmware updating guide (on the Technical Documents page.)
Cloning controller firmware
NOTE:
Cloning is possible only in dual-controller configurations.
Each time a system with two controllers is powered on or restarted, or if a second controller is hot-plugged
into a single-controller configuration, the firmware versions on the controllers are compared. If the
firmware versions on the two controllers are different, the array controller LCD panel prompts to clone the
firmware from one controller to the other, so that they have the same version.
The determination as to which firmware 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 firmware
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 firmware
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.
