Sun StorEdge 3310 Controller FRUs which come from Sun Logistics have version 3.66 firmware installed.  Because 3.66 firmware is not a production ready firmware it should not be used, and must be either upgraded to 4.x or downgraded to 3.25s/3.25w.  However, an upgrade to 4.x using the script "s3kdlres", in a single controller configuration, does not work.  3.66 is a special firmware which has the capability of crossloading to another controller having either 3.25s/3.25w or 4.x firmware in a dual controller configuration.  If used in production it can cause unpredictable behavior.  

This issue can affect any SE3310 Array in a single controller configuration when a new Controller FRU, P/N 370-5403-xx, is installed.  Dual controller configurations are not affected as the firmware crossloading process will complete correctly.

The Array Controller Module Replacement Guide for the Sun StorEdge 3310 (819-2181-13) describes the upgrade process.  While it is possible to downgrade the 3.66 firmware to 3.25s/3.25w, upgrading from 3.66 to 4.x using the script does not work.  Version 4.13B is the only currently released and available firmware version for the SE3310.  When an upgrade to 4.13B is attempted using the "s3kdlres" script, the following error message appears.

"Upgrades from firmware 366@ not supported"    

The best way to upgrade to 4.x with single controller configurations is to manually upgrade using sccli commands.  Please see details provided below.

Whenever an SE3310 Controller needs to be replaced in a single controller configuration running 4.x, these steps should be followed:

1. First refer to manual 819-2181-13.

2. Save a copy of the NVRAM to disk.

3. Manually upgrade to 4.13B firmware using this sccli command:

   sccli> download controller-firmware --reset-nvram -r SUN413B-3310.bin

Note: If the customer wants to run with 3.25 firmware, the controller would need to be downgraded. The command would instead be:

   sccli> download controller-firmware --reset-nvram -r SUN325W-3310.bin

4. After upgrading to 4.13B, restore the NVRAM from disk back to the controller.

For details on how to save/restore NVRAM, please see InfoDoc 75286, Sun StorEdge[TM] 3000: Saving and Restoring NVRAM and Logical Drive Configuration.
