Extending a Virtual Disk for an iSCSI Target
Applies To: Microsoft iSCSI Software Target
You can dynamically increase the size of an iSCSI virtual disk without losing data and without restarting the iSCSI target. In Microsoft iSCSI Software Target, you can use the Extend Virtual Disk Wizard to extend the virtual disk.
Note
The size that is displayed in the Microsoft iSCSI Software Target console may not be dynamically updated after you resize the virtual disk. Refresh the view in the console to display the new size.
The initial size of an iSCSI virtual disk is determined when the virtual disk is created. For more information about how the size of a virtual disk is initially specified, see Creating a Virtual Disk for an iSCSI Target.
