Creating Snapshots - HP StoreVirtual 4000 User Manual

Creating snapshots

Create a snapshot to preserve a version of a volume at a specific point in time. For information
about snapshot characteristics, see
Creating an application-managed snapshot, with or without volume sets, requires the use of the
Application Aware Snapshot Manager. The application-managed snapshot option quiesces
Windows and VMware applications on the server before creating the snapshot. For more
information, see
Aware Snapshot Manager is not installed, the SAN/iQ software creates a regular, point-in-time
snapshot.
Creating regular or application-managed snapshots
The snapshot creation process for application-managed snapshots differs when a Windows
application has associated volumes. See
using application-managed snapshots with VMware vCenter Server, you must first create a server
in the CMC and use the IP address of the application server on which the vCenter Server is installed
as the controlling server IP address in the New Server window.

the application before creating the snapshot, select Application-Managed Snapshot.
