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 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. maintenance and service guide 103

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.
