204 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
IBM Subsystem Device Driver DSM (SDDDSM) is the IBM multipath I/O solution that is based
on Microsoft MPIO technology. It is a device-specific module that supports IBM storage
devices on Windows hosts. The intent of MPIO is to provide better integration of a multipath
storage solution with the operating system, and it supports the use of multipath in the SAN
infrastructure during the startup process for SAN Boot hosts.
To ensure correct multipathing with the Storwize V5000, SDDDSM must be installed on
Windows hosts. To install SDDDSM, complete the following steps:
1. Go to the following SDDDSM download matrix to determine the correct level of SDDDSM
to install for Windows 2008 R2 or Windows 2012 R2, and then download the package:

2. Extract the package to your hard disk drive, and run setup.exe to install SDDDSM. A
command prompt window opens (Figure 5-2). Confirm the installation by entering Yes.

3. During the setup, SDDDSM also determines whether an older version is installed and
prompts you to upgrade to the current version.
4. After the setup completes, you are prompted to restart the system. Confirm this restart by
typing Yes and pressing Enter (Figure 5-3).
