• Install CV: Creates custom volumes from free space.

• Make Volume: Converts a custom volume back to a normal volume (VDEV).

The Make Volume function clears all custom volumes under a VSC volume and creates an initial volume

(VDEV) that consists of new user-defined custom volumes.

The Volume Initialize function uninstalls all custom volumes under a VSC volume, and reformats the VSC

volume as a normal volume (VDEV).

Compared to other emulation types, use OPEN-V to easily create volumes of any size. OPEN-V volumes

always consist of custom volumes, instead of fixed-size volumes.

CAUTION: VSC operations are destructive. Back up your data before performing VSC operations.

Figure 29 and Figure 30 show a sample VDEV (whose components are LDEVs) in its initial condition and

the VDEV after custom volumes are created.

Parity group configuration

This section explains the parity group configuration of emulation types other than OPEN-V. OPEN-V

volumes always consist of variable sized volumes instead of fixed-size volumes (FVs). To use OPEN-V,

parity groups must be enabled to support the OPEN-V emulation type. To enable OPEN-V, contact your HP

account support representative.

For emulation types other than OPEN-V, one parity group consists of a maximum of 16 VDEVs. For RAID-5

(7D + 1P) level or RAID-6 (6D + 2P) levels, a maximum of 512 fixed-size volumes (FVs), and a certain
