A controller that replaces a failed unit in a dual-controller system often has a newer release of the firmware installed than the firmware in the controller it replaced. To maintain compatibility, the surviving primary controller automatically updates the firmware running on the replacement secondary controller to the firmware version of the primary controller.

Note – When you upgrade your controller firmware in the Solaris operating system, the format(1M) command still shows the earlier revision level. To correct this, you must update the drive label using the autoconfigure option (option 0) of the format(1M) command. When you select label, the drive is labelled with the updated firmware version.

7.4.3Upgrading SES and PLD Firmware

When you replace an I/O controller, the new controller might have a version of SES or PLD firmware different from the other controller in your array. If this mismatch occurs, when you install a controller you hear an audible alarm and see a blinking amber Event LED.

To synchronize the SES firmware and hardware PLD versions, you must download new SES firmware through SANscape software or the SANscape Command-Line Interface (CLI).

If you have not installed this software, you must install it from the software CD that shipped with your array.

Refer to the SANscape User’s Guide to see instructions for downloading firmware for devices.

Refer to the SANscape CLI User’s Guide, or the sccli(1M) man page for similar instructions using the SANscape CLI.

Refer to the SANnet II 200 FC, SATA, and SATA SE Array Release Notes for instructions about where to obtain the firmware that you need to download.

When you open the SANscape software or the SANscape CLI and connect to the array, an error message alerts you to the mismatched version problem.

7.5Replacing the Front Bezel and Ear Caps

Some procedures require that you remove the front bezel and the small vertical plastic caps on either side of the bezel that cover the rackmount tabs. These rackmount tabs are referred to as “ears.”
