SnapDrive™ 4.1 for Windows® Description Page

Features of this Release

The SnapDrive™ 4.1 software contains all the features of SnapDrive 4.0 and introduces support for the following:

Use on x64 sytems and Windows OS:
- When using Windows Attach Kit 3.0 for FCP installations
- When using the Microsoft iSCSI Software Initiator 2.01
See the iSCSI Host Compatibility Matrix for the most up-to-date information about HBAs qualified for use with SnapDrive

Limitations

SnapDrive 4.1 does not support the following:

Use on IA64 systems
Management of VLDs and conversion of VLDs to LUNs
Use of volume mount points for Windows 2000® clusters
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 triggering of qtree-based synchronous mirroring (however, SnapDrive does support the use of SnapMirror to replicate volumes)
Connection to Data ONTAP MultiStore® virtual filer partitions other than the physical "hosting" filer [vfiler0], unless you are using Data ONTAP 7.2 or later. See the SnapDrive Compatibility Matrix on NOW for the latest information.
Extended partitions in a virtual disk (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 Use of QLogic iSCSI HBAs on the x64 Windows OS Volume mount points 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 Microsoft Cluster Service configuration (MSCS) that uses volume mount points, install Microsoft hotfix KB925677 on all cluster nodes.
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.

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

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 2.3.1 or later before upgrading to SnapDrive 4.1 on 32-bit systems.

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 new 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 new 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 2.3.1 or later before upgrading to SnapDrive 4.1 on 32-bit systems. See the SnapDrive 4.1 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 4.1 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, go directly to Step 5; you already installed one or both of these licenses when you installed SnapDrive 3.1 or later.

Download the SnapDrive 4.1 Installation and Administration Guide.
