Preface
1 Overview This chapter describes the HP StorageWorks EVA Hardware Providers (HWP) for Windows Server 2003 Enterprise Edition and explains how they operate with Microsoft’s operating system and applications. When you have read this chapter, you should have a functional understanding of the Hardware Providers that will prepare you to install the providers and get them working.
Simple overview HP StorageWorks EVA Hardware Providers for Windows Server 2003 are solutions that install on a Windows 2003 server connected to an HP disk array.
Detailed overview HP Hardware Providers enable Windows and its applications to use Microsoft VDS/VSS services to manage certain functions of the disk array. Virtual Disk Service (VDS) The VDS service provides the capability of Windows and Windows applications to recognize the HP disk array and perform basic and dynamic disk management functions. • Microsoft Management Console (MMC) Snap-in, Disk Manager and DiskPart command line interface use the VDS service.
Functional components The process of managing array volumes using VDS/VSS and HP HWP involves the following components: • • • • • • • • 12 Microsoft Windows Server 2003 OS Windows Disk Management Management Applications, such as HP’s Fast Recovery Solution (FRS) and third party programs Microsoft Command Line Utilities Windows Software Providers Windows VDS Service/VSS Service HP VDS/VSS Hardware Providers HP Disk Array System Overview
Microsoft Windows Server 2003 operating system The Windows Server 2003 OS includes Microsoft Virtual Disk Service (VDS) and Volume Shadow Copy Service (VSS). These services allow you to manage storage array disks and volumes and to perform data backup and restoration. The HP EVA Hardware Providers enable the VDS and VSS services to work with HP EVA disk arrays. The Microsoft Virtual Disk Service provides interfaces for managing storage devices. Windows Server 2003 included VDS 1.0.
HP Hardware Providers are not required in order for the Microsoft in-box or third party software providers to perform the tasks described above on the HP disk arrays. However, the HP HWPs extend the capabilities of various Windows providers and applications to do additional tasks that normally require the use of proprietary HP array management software. Such tasks include LUN and port management and more sophisticated volume copying.
There are two HP HWP installation executables for each HP disk array model, one installation executable for VDS and one for VSS. These installation executables are different for each HP disk array model. The HP Hardware Providers installation executables install the HWP files in your Windows Server file system. The files installed consist of special sets of HP DLLs and executables. These components extend the array management capabilities of Windows and its applications.
Shadow Copy Transport Using a server configured with suitable applications together with VSS and the HP HWP, you can create shadow copies and import them onto other servers connected to the same disk array. This enables multiple servers to make use of the same data, allowing data mining or testing on those servers. (However, shadow copies are read-only. If you need to write to a shadow copy, you must use a storage-management application that works with VDS/VSS to convert the copy to read/write.
2 Configuration This chapter lists required hardware and software components and explains how to configure the disk array and Windows 2003 servers for use with HP Hardware Providers (HWP). You must complete the procedures in this chapter before you install HP HWP. IMPORTANT NOTE: The right combination of software versions is crucial to configuring a working system.
Required components The following illustration summarizes the hardware and software in a fully configured system. A second server is not needed for VDS and is optional for VSS, but it may be useful if you want to manage VSS data copies without burdening the primary server. Note that any firewall must be open between the HWP server(s) and the Command View workstation. Anything that slows down access to the CV workstation will cause VSS timeout failures.
Required hardware components • HP StorageWorks Disk Array: EVA disk array with a Windows workstation for running Command View EVA. If multiple EVA disk arrays are used with FRS, all must be managed from one Command View workstation. • Windows VDS/VSS Server with Windows Server 2003 OS for connecting to the array. This primary server manages your primary data and contains applications (such as Exchange or SQL), VSS/VDS, and HP HWP.
Required software components The following software is required to run HP HWP. IMPORTANT NOTE: The right combination of software versions is crucial to configuring a working system. Refer to the Release Notes accompanying the HP HWP installation files for information about compatible software versions and system configurations. Follow all configuration and installation instructions carefully.
Configuration procedures Physically configure the servers and software as described below and in the manuals for those products. See the overview diagram under the heading Required components. Your HP representative may perform some installation and configuration tasks. Configuration summary You will perform the following tasks during configuration: Windows CV workstation: • Install HP MPIO FF Failover Manager (if multipathing is required). • Use Command View EVA to activate the BC license.
Configuring the VDS/VSS Server Install and configure the VDS/VSS server as follows: 1. If it is not already present, install the Windows 2003 Enterprise Server OS on the host according to Microsoft’s installation instructions. 2. If multipathing is desired, install the HP MPIO Full-Featured software according to the documentation for that product. 3. Install a Fibre Channel host bus adapter (HBA) card into the server according to the HBA manufacturer’s instructions. 4.
Configuring the EVA disk array The following configuration steps are required for both VDS and VSS Hardware Providers. The current HWPs work with EVA Command View 6.0 or higher. 1. For the HWPs to access the CV server, you must create new user names and user groups at the operating system level on the CV server. In Windows, click Start > Control Panel > User Accounts. 2.

3 Installation This chapter explains how to install Hardware Providers (HWP) and other required software. When you install HWP, all the features of VDS and VSS are enabled, including point-in-time copies of LUNs and storage virtualization management. If you have not already configured the server and the array as instructed in “Chapter 2 Configuration,” do so now before you install the HWP software. HWP will not work if the array and server have not been correctly configured before you install HWP.
Installation procedures The following procedures describe how to install the Hardware Providers. If you have not already configured the server and the array as instructed in “Uninstalling HWP,” do so now before you install the HWP software. HWP will not work if the array and server have not been correctly configured before you install HWP. For a summary of the configuration steps, see Configuration procedures.
Installing HWP Installation for VDS and VSS is very similar; therefore only VSS installation is described. However, each package must be installed individually. Install VDS first to provide disk management capability. If you also want to make data copies, install VSS second. 1. Before you start installation, use a ping command to test communication with the Command View EVA server. 2. Download and extract the HWP files from the HP VSS/VDS web page: http://www.hp.com/ support/HWPEVA 3.

4 Troubleshooting This chapter explains how to troubleshoot Hardware Providers (HWP) and also presents a list of VDS and VSS error messages and explanations.
Troubleshooting procedures The following instructions present typical problems and solutions. VDS/VSS HWP will not install The HP HWP installation works only on the Windows versions listed in the Configuration chapter of this guide and in the Release Notes supplied with the HP HWP. The installer will not install the software on other versions of Windows. CV authentication failure Smart Start v7.2 may cause login failures for applications such as HP HWP using the Command View EVA API.
4. Make sure you configured the VDS/VSS Configuration Utility as explained in Chapter 3 Installation. 5. Check configuration as explained in “Chapter 2 Configuration”: • Check LAN connectivity between all servers and the array. • Make sure the firewall is open between all servers and the array. • Check Command View server NIC bindings: the LAN that connects to the VDS/VSS server must be listed first. • Make sure you logged into all devices and software using administrator privileges.
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. • Review the Windows application event log, Windows system event log, and VSS trace to locate errors in the snapshot process. See the Microsoft website and Windows help for information about the log and trace files.
