228 IBM System Storage N series Hardware Guide
17.4.2 Preparation
Before you install the Host Utilities, verify that the Host Utilities version supports your host and
storage system configuration.
Verifying your host and storage system configuration
The Interoperability Matrix lists all supported configurations (individual computer models are
not listed). Windows hosts are qualified based on their processor chips. The Matrix is
available at this website:
http://www.ibm.com/systems/storage/network/interophome.html
The following configuration items must be verified:
Windows host processor architecture
Windows operating system version, service pack level, and required hotfixes
HBA model and firmware version
Fibre Channel switch model and firmware version
iSCSI initiator
Multipathing software
Veritas Storage Foundation for Windows software
Data ONTAP version and cfmode setting
Option software such as SnapDrive for Windows
Installing Windows hotfixes
Obtain and install the required Windows hotfixes for your version of Windows. Required
hotfixes are listed in the Interoperability Matrix.
Some of the hotfixes require a reboot of your Windows host. You can wait to reboot the host
until after you install or upgrade the Host Utilities. When you run the installer for the Windows
Host Utilities, it lists any missing hotfixes. You must add the required hotfixes before the
installer can complete the installation process.
Use the Interoperability Matrix to determine which hotfixes are required for your version of
Windows, then download hotfixes from the following Microsoft download website:
http://www.microsoft.com/downloads/search.aspx?displaylang=en
Enter the hotfix number in the search box and click the Search icon.
Confirming your storage system configuration
Make sure that your storage system is properly cabled and the Fibre Channel and iSCSI
services are licensed and started.
Add the iSCSI or FCP license and start the target service. The Fibre Channel and iSCSI
protocols are licensed features of Data ONTAP software. If you must purchase a license,
contact your IBM or sales partner representative.
Remember: If you add a Windows 2008 R2 host to a failover cluster after the Host Utilities
are installed, run the Repair option of the Host Utilities installation program. This process
sets the required ClusSvcHangTimeout parameter.
