To find this tool, see Resource Kit Tool Updates in Tools and Settings Collection.

Dynamic Disk and Volume Registry Entries

The following registry entries are associated with dynamic disks and volumes. For more information about the registry, see the Registry Reference in Tools and Settings Collection.

The information here is provided as a reference for use in troubleshooting or verifying that the required settings are applied. It is recommended that you do not directly edit the registry unless there is no other alternative. Modifications to the registry are not validated by the registry editor or by Windows before they are applied, and as a result, incorrect values can be stored. This can result in unrecoverable errors in the system. When possible, use Group Policy or other Windows tools, such as Microsoft Management Console (MMC), to accomplish tasks rather than editing the registry directly. If you must edit the registry, use extreme caution.

The following sections describe the dynamic disk and volume registry entries that are listed below \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\. The headings represent the next level in the path after \Services. For example, Vds\Debuglog is equal to \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Vds\Debuglog.

Vds\Debuglog

Level
Registry path

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Vds\Debuglog\Level

Version

Windows Server 2003 family.

Sets the level of logging for VDS.

Use Registry Editor to add a decimal value named Level. Stop and restart the service after changing.

VDS Log Options

Item Logged Bitmask Number

Errors

1

Warnings

2

Trace

4

Information

8

Set the value by adding the bitmask numbers of the values you want to log. For example, decimal 3 logs errors (1) and warnings (2). Decimal 9 logs errors (1) and information (8). The range for this value is 0-15. Set the value to 0xF (decimal 15) to log all items.

Dmadmin\Parameters

EnableDynamicConversionFor1394
Registry path

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\dmadmin\Parameters\EnableDynamicConversionFor1394

Version

Windows Server 2003 family.

Allows a user to convert a Institute of Electrical and Electronics Engineers, Inc. (IEEE) 1394 (FireWire) disk to a dynamic disk on Windows Server 2003 or earlier operating systems. Converting 1394 disks to dynamic is not a tested or supported scenario. This registry entry is provided for compatibility with a Windows 2000 beta that did support this functionality.

EnableDynamicConversionFor1394 is a DWORD Value, with a range of 0-1. Default is zero. To modify, use Registry Editor. Stop and restart the service after modifying.
