Hi gurus,
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office"

We have a SunFire 280R (1x 900MHz SPARC) here that we recently upgraded the
memory on - we replaced 4x 256MB DIMMs with 4x 1024MB DIMMs. We just did a
straight swap of the DIMMs, did a "boot -r" and brought the system up... the
following came up in the POST:
0>Memory in non-interleave config:........... OK1.0 par f
0> Bank 0 2048MB : 00000000.00000000 -> 00000000.80000000.
0> Bank 2 2048MB : 00000002.00000000 -> 00000002.80000000.plication
Server ............................. OK
As it had been recognised at the hardware level, I assumed that we had been
successful as I wasn't aware of any configuration changes that would need to
be done on the OS. Silly assumption to make as it turns out - I was away
last week and when I got back, our DBA told me that Solaris was only seeing
1GB of memory.
Sure enough, looking at the system using the 'prtconf' and 'prtdiag'
commands, the output is showing that there is only 1024MB (4x256MB DIMMs)
installed.
# prtconf

I've searched this and several other forums, run google searches all to no
avail - my question is, how do I get Solaris to recognise that we have
changed the memory? We are running Solaris 8 2/02 - output of 'uname -a' is
as follows:
# uname -a
SunOS ibtsfinance 5.8 Generic_108528-21 sun4u sparc SUNW,Sun-Fire-280R
Any help you can offer will be greatly appreciated!
Thanks and best regards
George.
