You can use the Create Virtual Disk Wizard to create an iSCSI virtual disk and enable iSCSI target access. The virtual disk is created as a file residing on an NTFS volume. As with any other file, the file system determines where to place the file on the physical disk. This offers flexible provisioning, snapshots that persist after restarting the iSCSI target server, and compatibility with replication software. When creating the virtual disk, specify the following:
The name of the folder and file must be specified using the full path for the virtual hard disk (VHD) file (for example C:\Virtual Disk\contoso1.vhd). You can create it in an existing folder or specify the name for a new folder and the wizard will create the new folder when it creates the virtual disk.
If you set up failover clustering for iSCSI storage, the virtual disk can reside only on a cluster disk.
Specify a fixed size for the virtual disk in megabytes (MBs) using whole numbers. A VHD file can later be extended using the Extend Virtual Disk Wizard. For more information, see Extending a Virtual Disk for an iSCSI Target.
It is useful to specify a description that readily identifies the content and purpose of the virtual disk. For example, you can specify the name of the group that is to have access to the virtual disk or the type of information that is to be stored on the virtual disk.
You can specify the iSCSI target that is to have access to the iSCSI virtual disk. The virtual disk is dynamically added without requiring a shutdown of the iSCSI target. If you do not specify an iSCSI target in the wizard, you can specify it at a later time. For more information, see Assigning a Virtual Disk to an iSCSI Target.
Caution Configuring a virtual disk for access by more than one iSCSI target can cause data corruption unless the virtual disk is part of a cluster environment, or the iSCSI initiators use a storage area network (SAN) file system to coordinate access to the storage.
|As an alternative to creating a new virtual disk, you can use the Import Virtual Disk Wizard to import a previously created virtual disk. For more information, see Importing a Virtual Disk.|
