SnapDrive™ 4.0 for Windows® Description Page

Features of this Release

The SnapDrive™ 4.0 software introduces support for the following:

Rapid LUN restore with Data ONTAP® 7.1 or later
Volume mount points for Windows 2000®, Windows 2003®, and Windows 2003 clusters
Unattended installation
Fractional space reservation monitoring for LUNs having less than 100% space reservation with Data ONTAP 7.1 or later

SnapDrive 4.0 recognizes Microsoft® Windows Hardware Quality Lab (WHQL) certified iSCSI HBAs. See the iSCSI Host Compatibility Matrix for the most up-to-date information about HBAs qualified for use with SnapDrive.

Limitations

SnapDrive 4.0 does not support the following:

Management of VLDs and conversion of VLDs to LUNs
Use of volume mount points for Windows 2000 clusters
Use on a 64-bit Windows OS
Use of LUN cloning
Use of SnapDrive to manage dynamic disks or raw disks
Use of qtree quotas (however, SnapDrive does support the use of qtrees without quotas)
Automatic trigger of qtree based synchronous mirroring (however, SnapDrive does support the use of SnapMirror to replicate volumes)
Connection to Data ONTAP MultiStore® virtual filer partitions (however, SnapDrive can connect directly to the physical "hosting" filer [vfiler0] in a MultiStore installation)
Extended partitions in virtual disks (SnapDrive only supports a single, primary partition on a virtual disk)
Use of QLogic™ iSCSI HBAs for Windows 2000 Microsoft Cluster Service (MSCS) with or without MPIO
Volume mount points are not supported for use with SnapManager 3.1.1 for Exchange and SnapManager 2.0 for SQL Server or earlier SnapManager versions

Considerations when using the Microsoft iSCSI software initiator:

In a noncluster configuration, the Exchange service and the SQL service must be configured with a dependency on the iSCSI software initiator service.
Use of the Microsoft iSCSI software initiator is not supported with the Windows 2000 Microsoft Cluster Service (MSCS).

System Requirements

The following table lists the SnapDrive system requirements.

Component	Requirement
Operating system on the filer	Data ONTAP software version 7.0.2 or later. The features rapid LUN restore and fractional spacing reservation monitoring for LUNs having less than 100% space reservation require Data ONTAP software version 7.1 or later.
Operating system on the filer	Note: For the most current list of supported Data ONTAP software versions, see the SnapManager and SnapDrive Compatibility Matrix.
Licenses enabled on the filer	iSCSI, if you plan to use iSCSI-accessed virtual disks FCP, if you plan to use FCP-accessed virtual disks SnapRestore® software, which is required only for restoring virtual disks from Snapshot™ copies SnapMirror, if you plan to use the SnapMirror option
Licenses enabled on the filer	Note: The iSCSI and FCP licenses supplied with SnapDrive enable all the CIFS functionality necessary for using SnapDrive. If you also want full-featured, direct CIFS access to a particular filer, you must install a separate CIFS license on that filer.
NetApp Host Agent	If you are running NetApp Host Agent (to manage SnapDrive host with DataFabric® Manager), you must upgrade to NetApp Host Agent software release 2.2.1 or later before upgrading to SnapDrive 4.0. Because NetApp Host Agent 2.2.1 is not shipped along with any version of DataFabric Manager, you must upgrade NetApp Host Agent separately. To download NetApp Host Agent, go to the NOW site, navigate to the software download page, and then choose NetApp Host Agent 2.2.1 or later from the list.
Hardware on the Windows host machine	500 MHz Pentium® III 256 MB system RAM Emulex® LP9002L-F2 or LP10000 HBAs for FCP, supplied by NetApp Emulex driver: If you are running SnapDrive 4.0 on a Windows 2003 host in an FCP environment, download and install Emulex driver 5-1.11a0 (release notes included in ZIP file). HBAs and NICs: To determine the number and type of HBAs and NICs required by each host in your SnapDrive configuration, see the section on selecting a SnapDrive configuration in the SnapDrive 4.0 Installation and Administration Guide. Obtain the latest firmware and drivers for the HBAs and network interface cards (NICs) you are using, to ensure high network bandwidth and ease of configuration. The NIC you use to facilitate data transfer for the Microsoft iSCSI software initiator can come from any vendor, but must have the appropriate LOGO certification: "Designed for Windows Server 2003" or "Designed for Windows 2000". The latest FCP driver and firmware for Windows 2000 is available on the NOW site. From this gateway, navigate to the SAN (FCP) Host Attach Kit for Windows download page. The Microsoft iSCSI software initiator must be downloaded from the Microsoft site. For directions and links, go to the NOW site, scroll to the iSCSI Host Support Kit item, select the appropriate platform, and then click Go. If you are using QLogic HBAs, see the iSCSI Host Compatibility Matrix for the most up-to-date information about HBAs qualified for use with SnapDrive.
Operating system on the Windows host machine	One of the following operating systems: Windows 2000 Server with Service Pack 4 (SP4) Windows 2000 Advanced Server with SP4 (for Windows-cluster configurations) Windows 2003 Standard Edition with SP1 Windows 2003 Enterprise Edition with SP1
Microsoft Windows hotfixes	Before you can install SnapDrive, your host machine must have the appropriate Microsoft hotfixes installed.
	Note: The Microsoft hotfixes 293778, 815198, 867818, 885294, 891957, 898790, 902837, and 903081 must be requested directly from Microsoft Product Support Services at http://support.microsoft.com/.
	Note: Specify the directory to which you want to download Microsoft hotfix 822831.
	For Windows 2003 If your host is running Windows 2003 Standard Edition or Enterprise Edition with SP1, you must install hotfixes 891957, 898790, 902837, and 903081.
	For Windows 2000 If your host is running Windows 2000 Server or Advanced Server with SP4, you must install hotfixes 293778, 815198, 867818, and 885294. Before installing hotfix 293778, see Bug ID 113541 in "Known issues" of the release notes.
	Note: Although SP4 includes hotfix 815198, sometimes this hotfix does not update correctly and you are prompted that this hotfix is required. If prompted, install the individual hotfix or re-apply SP4.
	Note: If your host is running Windows 2000 and you encounter the problem described in the Microsoft Knowledge Base article 822831, you must install hotfix 822831.

Preinstallation Steps
	Before you download and install SnapDrive, complete the following steps:
	Download the iSCSI-protocol license, if you are currently using VLD-type virtual disks. You need this license if you currently have iSCSI LUNS or you intend to create iSCSI LUNs (either from scratch or by converting VLDs). Download the FCP-protocol license, if you are currently using LUN-type virtual disks. You need this license if you currently have FCP LUNs or you intend to create FCP LUNs (either from scratch or by converting VLDs). If you are currently running NetApp Host Agent (to manage SnapDrive host with DataFabric Manager), you must upgrade to NetApp Host Agent software release 2.2.1 or later before upgrading to SnapDrive 4.0. Because NetApp Host Agent is not shipped along with any version of DataFabric Manager, you must upgrade NetApp Host Agent separately. See the SnapDrive 4.0 download page for more information. If you are currently running a SnapDrive version earlier than SnapDrive 3.1, you must install at least one of the following licenses at the time you upgrade or install the SnapDrive 4.0 software: Download the SnapDrive license for LUN provisioning and snapshot management. After you click the SnapDrive license link, navigate to the license by choosing the "Show me all" search method, selecting SDR-WIN, and then clicking Go. Download the MPIO license for MPIO path management. After you click the MPIO license link, navigate to the license by choosing the "Show me all" search method, selecting SDR-MPIO, and then clicking Go.
	Note: If you are currently running SnapDrive 3.1 or later, skip to Step 5; you already installed one or both of these licenses when you installed SnapDrive 3.1 or later.
	Download the SnapDrive 4.0 Installation and Administration Guide. Read Chapter 3, "Installing or Upgrading SnapDrive," in the SnapDrive 4.0 Installation and Administration Guide.
