The command psrinfo -pv is the command you are looking for. It gives you the number of physical cpus plus the count of virtual processor per physical processor.

For example on a V880 it looks like this:

The physical processor has 1 virtual processor (0)
  UltraSPARC-III+ (portid 0 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (1)
  UltraSPARC-III+ (portid 1 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (2)
  UltraSPARC-III+ (portid 2 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (3)
  UltraSPARC-III+ (portid 3 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (4)
  UltraSPARC-III+ (portid 4 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (5)
  UltraSPARC-III+ (portid 5 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (6)
  UltraSPARC-III+ (portid 6 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (7)
  UltraSPARC-III+ (portid 7 impl 0x15 ver 0x23 clock 900 MHz)

Hope that helps. :-)

EDIT

A multicore machine has e.g. this output

The physical processor has 4 virtual processors (0-3)
  SPARC64-VI (portid 1024 impl 0x6 ver 0x93 clock 2150 MHz)
The physical processor has 4 virtual processors (8-11)
  SPARC64-VI (portid 1032 impl 0x6 ver 0x93 clock 2150 MHz)
