LUN (VLL) and Volume Shredder User Guide (T5214-96094, November 2011)

The VLL operations include: Volume to Space, Install CV, Volume Initialize, and Make Volume.

• The Volume to Space function formats one or more of the LDEVs on a selected Virtual Device

(VDEV) into free space. This free space can be used to install one or more variable-sized

volumes (CVs) using the Install CV function or remain as free space for future usage.

• The Volume Initialize function removes all CVs under a Virtual LVI/LUN volume, and reformats

the Virtual LVI/LUN volume as a VDEV. You can delete all FVs and CVs in a VDEV, and then

create new user-defined CVs by using the Make Volume function.

For an overview of how the Volume Initialize function works, see Figure 1 (page 7).

For an overview of how the Make Volume function works, see Figure 2 (page 7).
