All,
Having a similar situation here. Hoping to get more feedback then Phil
ever did.
Is there a way through console only to worm back into the SP/rommon/reset?
I can boot an old msfc image on the RP (hybrid mode with both SP and RP
running IOS), but havent figured out anything further yet.
The questions comes down to whether remote console is sufficient or if
remote power is also required.

This morning we had a crash on a remote site router, a single-sup720
6504 running 12.2(33)SXI (I know, it needs upgrading).
I got in over our out-of-band network and found the sup sitting at
rommon, so typed reset, and it said:
System Bootstrap, Version 12.2(17r)S4, RELEASE SOFTWARE (fc1)
Technical Support: http://www.cisco.com/techsupport

Cat6k-Sup720/RP platform with 524288 Kbytes of main memory
...and then hung. I sent a break, typed reset, and it did it again...
and again... and again...
Normally I'd remote power-cycle it, but at this particular location we
don't have an inline switch, so I eventually had to ask a colleague who
was on-site to do it.
Looking at the above, it seems like the sup was stuck with the RP in
ownership of the console, and the SP somewhere (dead?). When I finally
booted via a power-cycle I saw the familiar:
System Bootstrap, Version 8.4(2) Release
Copyright (c) 1994-2005 by cisco Systems, Inc.
Cat6k-Sup720/SP processor with 524288 Kbytes of main memory
...and from there the SP booted, and then chain-loaded the RP and all
was well.
So - I conclude from this that you basically ALWAYS need remote power
cycling equipment on a 6500/sup720, as the split RP/SP processor setup
means you might get stuck and unable to boot.
Is this the case? Is there a command I could have typed at RP rommon to
make it cold-boot? The commands present seemed to be a sub-set of the
normal rommon commands, and told me weird things like:
rommon 3 > dir
This operation is not permitted after send-break.
...and:
rommon 5 > set
Access of environmental variables not permitted.
Please set confreg to 0 and reset if you want to make any changes.
