Purpose

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

Troubleshooting Steps

If the platform is totally dead and the XSCFU is inaccessible via the network port. The only way to gather any information is via the serial port on the XSCF.

If the XSCF doesn't boot correctly or fails post then the network is not configured.

You would need to connect a console to serial port and power on the system.

The console should start to display booting messages similar to the following.

Example 1 - XSCFU post detects a memory error
------------------------------------------------------------------
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 - XSCFU corruption
-----------------------------------------
XSCF uboot 01100001 (Feb 3 2011 - 14:43:12)

SCF board boot factor = 4080

SOLUTION
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.

All these errors we had to replace the XSCF to clear the fault.

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

For the M3000, the mbu needs replacement. No system operation is possible until the MBU containing the XSCF is replaced.

For the M4000/M5000, the XSCF needs replacement. No system operation is possible until the XSCF is replaced.

For the M8000/M9000, the indicted XSCF needs replacement. Continue operation on the other XSCF. XSCF redundancy is compromized until the XSCF is replaced.
