Configuring iSCSI Initiators iSCSI Configuration for Microsoft Windows using MS Initiator Installation and configuration information is included with the MS Initiator download (uguide.doc). It can also be downloaded from the Microsoft web site. Before implementing iSCSI using MS Initiator, please consider the following: • On pre-Vista operating systems, Microsoft does not support "dynamic" disks for use with the Microsoft iSCSI initiator. Adaptec recommends using the QLogic QLA4010/4050, which supports "dynamic disks", or using only "basic" disks with the Microsoft initiator to avoid unexpected behavior and possible data loss when using the MS initiator to connect to iSCSI targets in a Snap Server. • To extend the size of a basic disk on pre-Vista operating systems, use the diskpart.exe utility as described in "Using the Microsoft Diskpart Utility to Grow iSCSI Basic Disks" on page 68 or refer to Microsoft KB article 325590. The Microsoft knowledgebase can be found at http://support.microsoft.com. On Vista and Windows 2008 systems, use the disk management tool to resize the disks. Configuring Microsoft Services Installed on iSCSI Disks to Start Automatically iSCSI technology allows Snap Servers to host the data files for applications that otherwise require local disk storage, such as MS SQL Server 2000 and Exchange Server 2003. If you use the Microsoft initiator on Windows XP, Windows 2003, Vista, or Windows 2008 server, services installed on iSCSI disks will start up automatically by default once you have configured them to persistently reconnect. On the Windows 2000 server, however, you must edit the Windows registry to make the service dependent on the iSCSI Initiator Service. Caution Use the Registry Editor with caution. Changes suggested by Adaptec should be evaluated by qualified technical staff to ensure that they do not affect the proper functionality of the Windows implementation, installed applications, or other components on the Windows system whose registry is being modified. The result of any modifications to the Windows registry can vary, and implied outcomes of any modification suggested by Adaptec are NOT guaranteed, and may not be supported. Adaptec strongly recommends backing up your registry before making any modifications. Please see Microsoft Knowledge Base article 322755 (Windows 2000) for details on backing up and restoring the Windows registry. Configuring the Server to Persistently Connect 1 Create an iSCSI disk on the Snap Server (see "Creating iSCSI Disks" on page 76). 2 From the Target tab of the Initiator's Property dialog box, select the Target, click the Logon button, check the Automatically restore this connection when the 65

Configuring iSCSI Initiators
65
iSCSI Configuration for Microsoft Windows using MS Initiator
Installation and configuration information is included with the MS Initiator
download (
uguide.doc
). It can also be downloaded from the Microsoft web site.
Before implementing iSCSI using MS Initiator, please consider the following:
•
On pre-Vista operating systems, Microsoft does not support "dynamic" disks for
use with the Microsoft iSCSI initiator. Adaptec recommends using the QLogic
QLA4010/4050, which supports “dynamic disks”, or using only "basic" disks
with the Microsoft initiator to avoid unexpected behavior and possible data loss
when using the MS initiator to connect to iSCSI targets in a Snap Server.
•
To extend the size of a basic disk on pre-Vista operating systems, use the
diskpart.exe utility as described in “Using the Microsoft Diskpart Utility to Grow
iSCSI Basic Disks” on page 68 or refer to Microsoft KB article 325590. The
Microsoft knowledgebase can be found at
. On
Vista and Windows 2008 systems, use the disk management tool to resize the
disks.
Configuring Microsoft Services Installed on iSCSI Disks to Start Automatically
iSCSI technology allows Snap Servers to host the data files for applications that
otherwise require local disk storage, such as MS SQL Server 2000 and Exchange
Server 2003. If you use the Microsoft initiator on Windows XP, Windows 2003,
Vista, or Windows 2008 server, services installed on iSCSI disks will start up
automatically by default once you have configured them to persistently reconnect.
On the Windows 2000 server, however, you must edit the Windows registry to
make the service dependent on the iSCSI Initiator Service.
Caution
Use the Registry Editor with caution. Changes suggested by Adaptec
should be evaluated by qualified technical staff to ensure that they do not affect the
proper functionality of the Windows implementation, installed applications, or
other components on the Windows system whose registry is being modified. The
result of any modifications to the Windows registry can vary, and implied
outcomes of any modification suggested by Adaptec are NOT guaranteed, and may
not be supported.
Adaptec strongly recommends backing up your registry before making any
modifications. Please see Microsoft Knowledge Base article 322755 (Windows 2000)
for details on backing up and restoring the Windows registry.
Configuring the Server to Persistently Connect
1
Create an iSCSI disk on the Snap Server (see “Creating iSCSI Disks” on page 76).

From the Target tab of the Initiator’s Property dialog box, select the Target, click
the
Logon
button, check the
