1 Overview of HP StorageWorks hardware providers This chapter describes the HP StorageWorks hardware providers for Windows, and explains how they function with Microsoft operating systems and applications. HP hardware providers are software products that are installed on a Windows server connected to an HP disk array. They enable Windows operating systems and applications to control disk array functions and copy disk array data.
Management applications Management applications operate through the Microsoft VDS and VSS services and HP hardware providers to manage application data, manage array disks and volumes, perform backups, and restore data. Microsoft command-line utilities Microsoft command-line utilities can manage any storage device with a VDS or VSS hardware provider. • The DiskPart utility, which comes standard with Windows XP and Windows Server, is used to manage disks, volumes, and partitions.
HP VDS and VSS hardware providers The HP VDS and VSS hardware providers consist of DLLs and executables that are installed on your Windows server. These components extend the capabilities of Windows and its applications to manage HP disk arrays. You can install the HP VDS or VSS hardware provider, or both. Using Windows applications and the HP VDS hardware provider, you can manage array ports; discover and manage LUNs; format, partition, and mount volumes; and create and manage file systems and files.

Click Start > Control Panel, and then select Administrative Tools > Services. Right-click Virtual Disk and select Properties. Select Manual under Startup type, and click OK.
5. 6. 7. Check configuration as explained in the configuration and installation sections: • VDS/VSS server not connected to the SAN correctly. • For XP only: Check that a host group named SVOL exists with secondary LDEVs that match the parameters of the primary LUNs (same emulation type and size). Also check that a host group named SHADOW exists. No host WWNs should be associated with the SVOL or SHADOW host groups before installation.
• A writer application is not configured according to best practices. Consult the software manufacturer for recommended practices. For example, keeping database files small by creating more rather than larger files may speed up overall operation and database copying. Saving transaction logs to a different volume than the database may also speed up performance. • There are errors in the snapshot process.
