Goal

5.19.0 firmware now allows for the reprogramming of the SCC (System Configuration Card) used to maintain the identity of a LW8-class system.

The goal is to allow rapid replacement of a physically damaged card if the standard SCC duplicate turnaround time is not sufficient to meet a customer's needs, and a customer has specific software licenses tied to a HostID.

Important note

This procedure is not to be used except in the case of a physically damaged SCC. TSC has accepted the responsibility to verify this is the case through the issuance of an engineering mode password required to execute the reprogramming sequence. Misuse would compromise the infrastructure used to control ISV software licensing schemes.

This document also assumes that the person executing this procedure has experience working with and servicing LW8-class systems, and understands the ramifications of the use of engineering mode to perform this procedure.

Solution

Call Flow

If a V1280/E2900/Netra1280/1290 system experiences a physical failure of an SCC card, the anticipated call flow is as described below.

Important: Do not insert a new replacement SCC until after the engineering mode password has been entered and you are in the reprogramming routine. If you replace the card before this, you will wipe out the previous information stored in NVRAM and you will have to discover the previous values by other means.

• Customer logs call with Oracle
• Oracle engineer will be dispatched for on-site response
• Oracle engineer will verify issue, and verify that the customer requires a replacement SCC with the same information.
• Oracle engineer will order one replacement SCC - for example, 370-5155 or
  

  371-0795

• Oracle engineer will open a collaboration to L2 engineers
• Engineer will type "engineering" from the lom> command prompt and get the information required for L2 eng to generate an engineering mode password
• TSC will generate password and provide engineer with the attached procedures and examples.
• Oracle engineer should execute procedure 1 first and attempt to program the faulty card by hitting <RETURN> when prompted to insert a new card. Engineer should then verify the proper programming remains after the SC reboot.
• If this does not work, then the Oracle engineer should re-execute procedure 1, except, when prompted to insert a new card, actually insert a new card, reprogram it, and verify its proper programming. Then, mark on the new SCC card the HostID and MAC address information of the customer machine.
• Oracle engineer should then return the faulty SCC via CPAS so the reason for failure can be analyzed.

Procedure 1 - attempt to recover a card which has "forgotten" its information or is blank.

• Boot system
• System will stop requesting a valid SCC or engineering password
• Enter <return> to get parameters to generate an engineering mode password
• Enter engineering mode password, which will invoke the SCC reprogramming procedure
• Enter the new MAC and HostID information, or, accept the values listed if they are correct.
• Confirm ok to program
• Verify programming by rebooting SC
• Record new information on SCC

Procedure 2 - reprogramming a pre-programmed card:

• Install new card
• Boot system
• Type engineering to get parameters to generate an engineering mode password
• Enter engineering mode password, switching to engineering mode
• Issue the following command:

seprom SCC -create_scc

• Enter the new MAC and HostID information
• Confirm ok to program
• Verify programming by rebooting SC
• Record new information on SCC
• Exit engineering mode
• Reboot the SC
