Release Notes:



*Data Path Protection 



         This firmware change has a new Data Path Protection feature. 

         The Data Path Protection firmware is intended to provide a method for

         confirming the integrity of the data path through the SAN Data

         Gateway. This test uses pattern data moved through various memory 

         interfaces to insure that all data paths into and out of command 

         processing memory and data flow memory (DDF) are correctly functional. 

         For detailed information on data path errors generated with this 

         new level of firmware, use the "2108 G07/R03 Firmware and 2108 G07 

         Extended DDF Memory Testing Testing" document located at website:

         cdr/Firmware/sdgfw.htm.



* Ethernet Loopback Diagnostic



	If you boot the SAN Gateway in diagnostic mode, and attempt to run the

        Ethernet loopback test (elTest), a message will be displayed indicating

        that the Ethernet loopback test is not avaliable. This test will remain

        disabled until further notice. During the absence of the Ethernet 

        loopback test, in normal boot mode you can verify that the Ethernet port

        is operational by connecting it to a LAN and see if the SAN Gateway 

        responds to a "ping". 

        



* User Accounts Invalid After Firmware Update



	If firmware version 3.41.31 or lower was running when user accounts

	were created for the purpose of accessing the command-line interface

        via Ethernet, and the firmware was subsequently updated to version 

        3.41.32 or higher, user accounts are no longer valid and you won't be

        able to log in. This is due to an operating system update that changed

        password encryption.

	Use the following procedure to delete and re-add the user accounts:



	1. Connect to the service port and start a terminal emulation session.

	2. Delete the password file by issuing the rm "MGMT/PASSWD" command.

	3. Issue the reboot command.

	4. Re-add the user accounts using the userAdd "username","password" command

	   as documented in the Service Port Command Reference.



	Note: If an older version of firmware is subsequently installed, this same

	      procedure will need to be followed before you can log in.
