Purpose

This is to aid with gathering information from a Mx000 system that the XSCF is unaccessable via the network.

Troubleshooting Steps

If the system is totally dead and you are unable to access the XSCF via the network port. Then the only way to gather any information is via the serial port on the XSCF.

Connect a console to serial port and power on the system.

You may see errors similar to the following.

Example 1
---------
XSCF uboot 01080001 (May 8 2009 - 15:09:36)

SCF board boot factor = a080
memory test ..
Memory compare test

memory error detect 80000008, address 00000000 data aaaaaaaa -> deadffef
capture_data hi deadffef lo deadbeef ecc eeee
capture_attributes 01113001 address 00000000 <------ Notice that the XSCF stops here so no further information.
---------

Example2
------------
XSCF uboot 01100001 (Feb 3 2011 - 14:43:12)

SCF board boot factor = 4080
memory test ..
Memory compare test

----------------

If the XSCF doesn't boot correctly or fails post then no network is configured.

Both these SR ended up with the XSCF being replaced but without this information we have no idea what is happening on the XSCF.

Once the XSCF was replaced this booted normally and the customer could administer the system via the network.

As part of your data collection when opening a service request with Oracle, connect to the serial port of the XSCF and gather the boot logs of the XSCF to allow the issue to be investigated in a timely manner.
