Limitations

SnapDrive 4.2.1 does not support the following:

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 asynchronous mirroring (however, SnapDrive does support the use of SnapMirror to replicate volumes)
Extended partitions in a virtual disk (SnapDrive only supports a single primary partition on a virtual disk)
Volume mount points for use with SnapManager 3.1.1 for Exchange and SnapManager 2.0 for SQL or earlier SnapManager versions

SnapDrive 4.2.1 does not support the following when using Data ONTAP DSM 3.0 for Windows MPIO:

Use of iSCSI. See "Upgrade and revert information" in the release notes for more information.
Use with Windows 2000 MSCS
Use of iSCSI and FCP on the same host

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 if you encounter the issue described in the KB article.
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 MSCS.

System Requirements

The following table lists the SnapDrive system requirements.

Component

Requirement

Operating system on the storage system

Data ONTAP 7.0.2 or later.

For use with Data ONTAP DSM for Windows MPIO, see the Data ONTAP DSM for Windows MPIO NOW Description page for any installation requirements.

The features rapid LUN restore and fractional spacing reservation monitoring for LUNs having less than 100% space reservation require Data ONTAP 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 storage system

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
FlexClone, which is required to enable volume clone functionality

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 storage system, you must install a separate CIFS license on that storage system.
