Cloning and Snapshot

The HP Storage plug-in facilitates the following:

•

Clone an existing SAP system—You can either choose the Full Clone or the Snap Clone option
to create a clone. Cloning the SAP system is a multi-step process. To clone storage related
tasks, SAP LVM delegates a request to HP 3PAR or HP XP Adapter based on the storage system
from which the storage for the SAP system originates. HP Storage Adapter triggers a full clone
or snapshot creation request on the Storage system based on the SAP system cloning option
that you have chosen while triggering the clone operation in SAP LVM.

NOTE:

Virtual Volume sets on HP 3PAR StoreServ are not supported in the current release

of HP Storage plug-in.

•

Clone from an existing snapshot of SAP system—This feature is supported for HP 3PAR StoreServ
only.

•

Snapshot of an existing SAP system—The snapshot of the SAP system is a point in time copy
of the SAP system. To take a snapshot, SAP LVM delegates a request to HP 3PAR or HP XP
Adapter. The Adapter in turn triggers a snapshot creation request to the Storage system.

Full Clone

A full clone is the full copy of a volume. Data stored in a full clone is static; it is not updated with
subsequent changes to the parent volume. The parent volume is the original volume that is copied
to the destination volume.

You can create a full clone of a volume from the parent volume only if the associated pool of the
volume has enough space to create the target clone disk to accommodate write operations to that
volume during full clone. Full clones can be online or offline.
