I received several replies to this, not sure if any will work, but must do
more investigating first. Thanks to all who replied.

[Alphaserver doesn't appear to have halt button???]
"Don't press the reset button, press halt.
If/when it returns to the SRM prompt (>>>), then issue the crash command.
Reset clears the memory, at which point you can't force a crash dump."
-------------------------------------------------------------------------------
[useful info if I ever get a dump....]
"If it saved the dump do :
>>> init
>>> boot
As the system goes into multi-user it will save the crash dump to
/var/adm/crash. The init is necessary because the hardware isn't reset
fully when you halt out of the boot sequence."

[Useful extensive info for a variety of systems]
For: 8400 and 7000 systems: (glacier)
1. Type Ctrl/P (that's the ctrl key and P key at same time).
2. Note the PC value for later analyze of hang.
3. Use method A, B, or C from below.
4. boot (reboot system after dump completes)
For: 2x00 and 4000 systems: (spike/nugget)
1. Press the halt button.
2. Note the PC value for later analyze of hang.
3. Use method A, B, or C from below.
4. boot (reboot system after dump completes)
For: 3000 systems: (moka/java)
1. Press the reset button.
2. Note the PC value for later analyze of hang.
2.1 '>>> login' (if console security enabled)
3. Use method A, B, or C from below.
4. boot (reboot system after dump completes).
---------------------------------------
Method A: At the console prompt: '>>> crash'
Note: If 'Method A' does not work try 'Method B' then 'Method C'.
Method B and C:
For 'B' or 'C' you must have the start (B) or doadump (C) address.
These are displayed from rc3.d/S99UA_init and captured in:
/sbin/init.d/UA_init.log which is copied to
~sxsysu/config/<host>/UA_init.log which are copied to
/usr/local/doc/recover/crash.address (nugget and java).
For a 3000: >>> set radix 16 (if necessary)
>>> start fffffc0000XXXXXX
For a 2000, 4000, 7000, etc.: >>> deposit pc fffffc0000XXXXXX
>>> continue
B: Use kernel 'start' address from `# nm -x /vmunix | grep '^start '`.
C: Use kernel 'doadump' address from `# echo doadump/X | dbx -k /vmunix`.
