Configuring iSCSI Initiators
79
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. Overland Storage 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 SnapServer.
• 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 82 or refer to Microsoft KB article 325590. The
Microsoft knowledgebase can be found at
. On
Vista, Windows 2008, and Windows 7 systems, use the disk management tool to
resize the disks.
Configuring Microsoft Services Installed on iSCSI Disks to Start Automatically
iSCSI technology allows SnapServers 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, Windows 7, 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 Overland
Storage 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 Overland Storage are NOT
guaranteed, and may not be supported.
Overland Storage 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 SnapServer (see “Creating iSCSI Disks” on page 91).
2
From the Target tab of the Initiator’s Property dialog box, select the Target, click
the
Logon
button, check the
