I don't have access to Solaris box right now so I don't know if this solution is very reliable:
Code:
mem=`prtdiag | tr -s "\t" " " | awk '/^0x0/{print $2}'`

This will put number of gigabytes of RAM into "mem" variable.

That's nice and clean, but I don't know if this will work on all systems of this type. I'll have to try this on similar boxes in our other data centers.

It won't work if there will be more memory segments in the server. I think something like this could work in that case:
Code:
mem=`prtdiag | tr -s "\t" " " | awk '/^0x[0-9a-f]/{x+=$2}END{print x}'`

Anyway let me know how did it go Smilie

The 'lgrpinfo' utility might do it. I don't recall offhand when that was rolled into Solaris 10 so you may not have it, and it may not work under LDOMs, but it's designed to show physical RAM configuration.

It's not in the 10/09 release.
