Options indicate an action to be performed:
If geomspec is specified, the vnode device will emulate the specified disk geometry. The format of the geomspec argument is:
ntracks/
ncylinders Xc
If geometry is not specified, the kernel will choose a default based on 1MB cylinders. secsize is the number of bytes per sector. It must be an even multiple of 512. nsectors is the number of sectors per track. ntracks is the number of tracks per cylinder. ncylinders is the number of cylinders in the device.
/etc/disktab

/etc/disktab
and use the geometry specified in the entry. This option and the
geomspec
argument are mutually exclusive.
If no action option is given, -c is assumed.
