Configuring iSCSI Initiators
68 Snap Server Administrator Guide
Configuring 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 web site
( uguide.doc ).
Using 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 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
Microsoft Knowledge Base article Q300415 ( http://support.microsoft.com/kb/
300415 ).
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
diskpart -
at the command line. If the command returns
command not
found,
locate diskpart on the Microsoft website, download the utility, and install
it on the local host.
3
Log off the iSCSI volume that is to be expanded.
• Open the Microsoft initiator tool.
• Under Connected Targets, highlight the specific iSCSI disk(s) you want to
expand.
• Click
LogOff
. This will log you off the specific target.
