Symptoms

 T6340 will not power on. Upon issuing the start /SYS command, the system starts POST but seems to hang at different points during POST.

Example of a POST hang:

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y

Serial console started.  To stop, type #.

0:0:0>Init MMU.....
0:0:0>L2 Tests....Done
0:0:0>Extended CPU Tests....Done
0:0:0>Scrub Memory....||     <--- POST hangs here

 

Another example of POST hanging at a different and earlier spot:

0:0:0>VBSC selecting Normal mode, MAX Testing.
0:0:0>VBSC setting verbosity level 2
1:0:0>NODE 1 present
0:0:0>Test Memory....Done
0:0:0>Setup POST Mailbox ....Done
0:0:0>Master CPU Tests Basic....Done
0:0:0>Init MMU.....
0:0:0>L2 Tests....Done
0:0:0>Extended CPU Tests....|/  <--- POST hangs here

 

 When trying to reset the system controller from the ILOM cli, the following errors are seen:

-> reset /SYS
Are you sure you want to reset /SYS (y/n)? y
Performing reset on /SYS
Performing reset on /SYS failed
reset: Internal error

 

 The output from show /SP/logs/event/list shows errors similar to this:

983    Sat Jan  1 00:10:12 2013  Fault     Fault     critical    SP detected fault at time Sat Jan  1 00:10:12 2013. Host Power Failure: MB_DC_POK Fault
