cpu pairs - two becomes one?
2007-12-24 20:15:00
I have a a few dual processor E250's (Solaris
2.6)none of which claim to acknowledge the presence of
the second processor with the commands:-
Blake# psrinfo
0 on-line since 06/11/01 10:21:51
Blake# psrinfo -v
Status of processor 0 as of: 07/03/01 16:27:43
Processor has been on-line since 06/11/01 10:21:51.
The sparc processor operates at 400 MHz,
and has a sparc floating point processor.
Blake# psrinfo -s 1
psrinfo: processor 1: Invalid argument
Blake# mpstat
CPU minf mjf xcal intr ithr csw icsw migr smtx srw
syscl usr sys wt idl
0 1 0 0 311 111 158 0 0 0 0
1013 0 1 1 98
Blake# /usr/platform/`uname -i`/sbin/prtdiag -v
etc
Any ideas? I did find reference to a patch (104595) -
but not for this chip. Also "Summary: UE450 with
disappearing CPU" (5 Jul 99) refers to setting
upa-noprobe-list to 0 at the OK prompt, but this
variable does not exist for this platform.
Also how does one find out the revision number of the
cpu? A while back Sun reported that some cpu's had a
prob with cache memory and I thought it was possible
to check this against the cpu revision number.
Many Thanks
will summarize
