Use the vmkfstools command to get information about the geometry of a virtual disk.

-g|--geometry

The output is in the form: Geometry information C/H/S, where C represents the number of cylinders, H represents the number of heads, and S represents the number of sectors.

Note:

When you import virtual disks from hosted VMware products to the ESXi host, you might see a disk geometry mismatch error message. A disk geometry mismatch might also trigger problems when you load a guest operating system or run a newly created virtual machine.
