Solaris sun4v - how do you determine physical RAM?
I have a Sun T5120, and I want to programmatically determine how much RAM it has.

Code:
# uname -a 
SunOS myhost 5.10 Generic_141444-09 sun4v sparc SUNW,SPARC-Enterprise-T5120

The box has 64Gb; I tried prtdiag and prtconf, but they give me bogus info

prtconf gives me:

Code:
# prtconf |grep -i "memory size"
Memory size: 1024 Megabytes


prtdiag gives me:

Code:
System Configuration:  Sun Microsystems  sun4v SPARC Enterprise T5120
Memory size: 1024 Megabytes

================================ Virtual CPUs ================================


CPU ID Frequency Implementation         Status
