C Managing MPIO devices using Microsoft-provided interfaces on Windows Server 2008 This appendix describes how to manage MPIO devices using the Microsoft-provided interfaces on Windows Server 2008. Beginning with Microsoft Windows Server 2008, Multipath I/O (earlier called MPIO framework) is provided as an operating system feature. Along with the feature, a few interfaces are provided to enable you to manage the MPIO framework and devices. Microsoft also supplies an inbox Microsoft DSM (MS DSM), which provides multipath support for SCSI-3 compliant disk devices. This appendix addresses the following topic: • Multipath I/O feature • Managing multipath support • Managing multipath disk devices Multipath I/O feature Multipath I/O feature enables the operating system to manage the disk devices that support multipathing. You must enable this feature before managing devices that support multipath. Installing the HP MPIO MSA DSM automatically enables the Multipath I/O feature. Alternatively, you can enable this feature manually as follows: 1. Go to Server Manager and select Features > Add Features. The Add Features Wizard page displays. 2. Select Multipath I/O. The MPIO framework and MS DSM are installed, and the MPIO applet is added to the Control Panel. Managing multipath support Microsoft provides a Control Panel applet that enables you to manage multipath support for disk devices. This interface allows users to enable or disable multipath support for the selected devices, allows users to install vendor-specific DSM, or both. To use the applet, go to Control Panel and select MPIO. The MPIO Properties page displays. The MPIO Properties page includes the following tabs: • MPIO-ed Devices • Discover Multi-paths • DSM Install MPIO-ed Devices When initiated, the MPIO Properties page defaults to the MPIO-ed Devices tab. This tab displays the Device Hardware IDs of the devices that supoprt multipathing and are currently managed by MPIO. Figure 1 shows the MPIO Properties page with the MPIO-ed Devices tab enabled.

install vendor-speci
fi
c DSM, or both.
To use the applet, go to
Control Panel
and select
MPIO
. The MPIO Properties page displays.
The MPIO Properties page includes the following tabs:
•
MPIO-ed Devices
•
Discover Multi-paths
•
DSM Install
MPIO-ed Devices
When initiated, the MPIO Properties page defaults to the MPIO-ed Devices tab. This tab displays the
