Volume Initialize and Make Volume functions

You can initialize a CVS volume using one of the following functions: Volume Initialize or Make Volume.
The Volume Initialize operation de-installs all variable-sized volumes under a CVS volume, and reformats

the CVS volume as a normal volume (FV). You must assign CU and LDEV numbers to the new formatted

FV. Any existing FVs on the original VDEV are not reformatted.
The Make Volume operation deletes all volumes in a VDEV, and creates new variable-sized volumes (CVs)

according to the specified settings. You can specify the following settings (see

Table 30

).
