To Configure Dynamic Disks to Persistently Reconnect. On pre-Vista operating systems,
when iSCSI targets are configured as dynamic disks, the Microsoft iSCSI initiator
connecting to the dynamic disk may fail to connect properly during system boot. Using
dynamic disks for iSCSI targets on pre-Vista operating systems is not supported by
Microsoft. For more information, see the Microsoft iSCSI Software Initiator User's Guide,
available on the Microsoft website (uguide.doc).
To Use the Microsoft Diskpart Utility to Grow iSCSI Basic Disks. In a Microsoft
environment, basic disk is the simplest configuration method for an iSCSI disk. Basic disks
are given the highest priority at both system and application services startup to ensure
proper initialization.
For Vista, Windows 7, and Windows 2008 Server, use the Disk Management utility. For
Windows 2003 Server, Windows 2000 Server, and Windows XP, Microsoft offers a command
line utility called Diskpart that allows you to expand basic disks. This utility ships with
Windows 2003 Server, and is available for download for Windows 2000 Server and XP.
Additional details on the Diskpart utility can be found in

Step 1: Preparing to Expand a Microsoft Basic iSCSI Disk
The following steps must be taken to prepare for the expansion of a basic iSCSI disk from a
Windows host:
1. Using the Microsoft Services GUI, stop all application services that are using the
volume you intend to expand.
2. If it is not already installed, load the Diskpart utility on the host machine that is
running the iSCSI initiator
NOTE: If Diskpart is already installed, you will get the appropriate response when entering
3. Log off the iSCSI volume that is to be expanded:
a. Open the Microsoft initiator tool.
b. Under Connected Targets, highlight the specific iSCSI disks you want to expand.
c. Click LogOff. This will log you off the specific target.
4. Verify that you have additional space available on the SnapServer to expand an
existing volume:
a. Open the Web Management Interface from a client on the network.
b. Navigate to Storage > iSCSI .
c. Select the iSCSI disk you intend to expand.
d. From the configuration page, ensure that you have additional space on the volume
e. Make changes to the iSCSI disk size as desired.
f. Click OK. The disk should now reflect the larger size.

at the command line. If the command returns
diskpart -
locate Diskpart on the Microsoft website, download the utility, and install it on the local
host.
If you have not disconnected from the iSCSI disk at the host, you will be unable to
proceed to the configuration page.
