VMware Capacity Planner shows some systems are not consolidatable

Hi,

I am using Capacity planner version 30 to asses 18 servers in the prospect client environment. Most of the machines are Dell 1950 and Dell 2950 running Windows 2003 operating system.

In data collector window, it shows all the inventory of systems but shows "consolidatable=false". Why is that happening? How can we make it "True".

Whereas in data collector dash board it doesnt show the inventory of the same systems.

Out of 18 servers only 2 servers are ready for review.

Please suggest.

Regards,

Atif
