The file shares that you create for folders that are located on your iSCSI device may not be re-created when you restart the computer that the shares are created on. The Server service creates file shares.
If you see the target on the Persistent Target tab, the following steps are not required. To do this, use one of the following methods. Select Bind All to bind all the persistent targets.
Or, select Addand then enter a drive letter or mount point to bind a specific target. This is the same as selecting the Bind All option in Method 1. NOTE] Use this resolution only if you experience this specific issue with version 2.
You do not have to modify the registry when you use this method. Therefore, this method is the preferred way to set the service dependency.
If you have administrative access to the server, you can run this command from a network computer. This section, method, or task contains steps that tell you how to modify the registry.
However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully.
For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: How to back up and restore the registry in Windows. You can script the procedures that are described in the "Resolution" section by using the Sc.
To do this, create a batch file that uses these commands, and then either run the batch file directly, or run the batch file in another way. For example, run the batch file by using Group Policy.

If you go to it the wrong way you will not find it. Again, if you get to this window a different way, the "Details" tab may not appear. This is what has been suggested before, but does not work.
I need working code, not links to text that suggests how to do it, they don't seem to work in WPF. Besides, if it did, why would they not post the actual code they used. Thanks, but no thanks. I am not interested in any products where I must abide by their license agreement, no mater how liberal it is.
The two together represent the Device Instance ID. WPF wasn't introduced until Finding code for none-WPF is easy. Its finding code for WPF that is difficult. I found no "Device Instance Path", but maybe that's the name used by newer Windows operating systems such as Vista and 7, but I don't know. Just plugged one in, followed your instructions and Device Instance Id does not show in the dropdown. I am on Win7. I just tried it with a small program and not much works.
I had to add a mo. Get ; to get anything. I was on Win7 64bit as well. I imagine XP is different. Regardless, the issue still remains how do you get the appropriate entry. What did you mean earlier by stating that you were looking for a WPF answer? This issue is a.This article discusses the manner in which Windows supports hard disks that have a storage capacity of more than 2 TB and explains how to initialize and partition disks to maximize space usage.
In order for an operating system to fully support storage devices that have capacities that exceed 2 terabytes 2 TB, or 2 trillion bytesthe device must be initialized by using the GUID partition table GPT partitioning scheme.
This scheme supports addressing of the full range of storage capacity. It also describes the requirements to address the full storage capability of these devices. LBA0 represents the first logical sector of the device, and the last LBA designation represents the last logical sector of the device, one label per sector. To determine the capacity of the storage device, you multiply the number of logical sectors within the device by the size of each logical sector.
The current size standard is bytes. For example, to achieve a device that has a capacity of 2 TB, you must have 3, byte sectors. However, a computer system requires 32 bits 1 s and 0 s of information to represent this large number.
Therefore, any storage capacity that is greater than what can be represented by using 32 bits would require an additional bit. That is, 33 bits. The problem in this computation is that the partitioning scheme that is used by most modern Windows-based computers is MBR master boot record.
This scheme sets a limit of 32 for the number of bits that are available to represent the number of logical sectors.
The 2-TB barrier is the result of this bit limitation. Because the maximum number that can be represented by using 32 bits is 4, this translates to 2.
Therefore, a capacity beyond 2. To make more bits available for addressing, the storage device must be initialized by using GPT. This partitioning scheme lets up to 64 bits of information be used within logical sectors. This translates to a theoretical limitation of 9. By default, many current systems can support UEFI. Microsoft expects that most future systems will have this support. Customers should consult with their system vendor to determine the ability of their systems to support UEFI and disks that have storage capacities that are greater than 2 TB.
For a system to be able to address the maximum capacity of a device that has a storage capacity of more than 2 TB, the following prerequisites apply:.This article describes the support for a large number of logical unit numbers LUNs in Windows Server products. This article contains information about how to modify the registry. Make sure to back up the registry before you modify it.
Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, click the following article number to view the article in the Microsoft Knowledge Base: Description of the Microsoft Windows registry.
When you configure a server with more than eight LUNs, the hardware vendor must be involved in the planning and configuration. There may be several different ways to achieve the configuration you want; the hardware vendor is best equipped to supply the necessary information.
This article isn't meant to be all-inclusive because of the various implementations that a hardware vendor can use. Contact your hardware manufacturer to determine if and how your hardware can support more than eight LUNs. Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved.
Modify the registry at your own risk. Windows Server supports Large LUNs, but the method for enabling it depends on the hardware implementation and drivers. If the storage device reports the HiSupport bit in its standard inquiry data, Windows automatically enables Large LUNs without requiring any manual registry entries.
Contact the hardware vendor to determine if the storage device reports the HiSupport bit. The hardware drivers may also enable large LUN support during their installation routines. If the hardware doesn't report the HiSupport bit, or the drivers don't enable Large LUN support, a manual registry entry is required.

Note that editing the registry to enable Large LUNs requires detailed knowledge of the devices' hardware IDs and registry entries; this is the least-preferred method. Contact the hardware vendor for additional information. Follow these steps to configure the required registry entry:. There may be several hardware IDs for the same device. This occurs because the device may be detected in different ways for different firmware revisions of the same device. You may have to try each of the different hardware IDs in the following steps.
If you have any problems with this, contact your storage device hardware manufacturer.The Plug and Play PnP manager and other device installation components use device identification strings to identify devices that are installed in a computer.
Windows uses the following device identification strings to locate the information INF file that best matches the device. These strings are reported by a device's enumerator, a system component that discovers PnP devices based on a PnP hardware standard. Windows tries to find a match for one of the hardware IDs or compatible IDs. In addition to using the preceding IDs to identify devices, the PnP manager uses the following IDs to uniquely identify instances of each device that are installed in a computer:.
Starting with Windows 7, the PnP manager uses the Container ID device identification string to group one or more device nodes devnodes that were enumerated from each instance of a physical device installed in a computer.
Each enumerator customizes its device IDs, hardware IDs, and compatible IDs to uniquely identify the device that it enumerates.
In addition, each enumerator has its own policy to identify hardware IDs and compatible IDs. Device identification strings should not be parsed. They are meant only for string comparisons and should be treated as opaque strings. Skip to main content. Contents Exit focus mode.
