Wow what quick response. Thanks to the many folks who replied.
The overwhelming response was to use the memconf.pl script available from
Sunfreware or http://www.4schmidts.com/memconf.html.
This provides exactly the detailed config info I needed. It works well for
most systems, especially the Netra 20 & 1120 units however for the 1400 it
has problems that are the fault of the 1400's prom logic. It provides the
following output:
-----------------------
Netra t 1400/1405 (4 X UltraSPARC-II 440MHz)
socket U0301 has a 256MB DIMM
socket U0302 has a 256MB DIMM
socket U1301 has a 256MB DIMM
socket U1302 has a 256MB DIMM
empty sockets: U0401 U0402 U1401 U1402 U0303 U0304 U1303 U1304 U0403 U0404
U1403 U1404
total memory = 1024MB (1GB)
WARNING: Layout of memory sockets not completely recognized on this system.
The memory configuration displayed is a guess which may be incorrect.
The 1GB of memory installed may be 4 256MB DIMMs populating any 1 of
the 4 banks, 8 128MB DIMMs populating any 2 of the 4 banks, or 16
64MB
DIMMs populating all 4 banks.
This is a known bug due to Sun's 'prtconf', 'prtdiag' and 'prtfru'
commands not providing enough detail for the memory layout of this
SunOS 5.8 SUNW,Ultra-80 system to be determined.
This is not a bug in memconf, rather it is a bug in Sun's OBP.
The latest release (OBP 3.31.0 2001/07/25) still has this bug.
This system is using OBP 3.31.0 2001/07/25 20:35

Thanks again,
Jon
original question follows:
I have several netra20, 1120 & 1400 units that I need to know exact memory
configurations without physical access to the box. These units are in 24x7
production and connot be taken out of service easily to unrack & open to
check the configuration.
Is there a way to remotely determine what memory slots are being used? The
prtdiag command only shows total memory installed. I need some way to
determine just what slots, i.e. j0404, j0405...that are filled. Is there a
diagnostic available that will provide this data or can you recommend how to
accomplish this remotely. Note, we do have remote console access to the box
in the event the boot prom can provide the data through POST diagnostics,
however it would be vastly preferred to do it without rebooting the box.
Thanks in advance
Jon
