Resolving Microsoft Windows Upgrade Problems
If you upgrade the Microsoft Windows operating system on a server, you may
find that Storage Management no longer functions after the upgrade. The
installation process installs files and makes registry entries on the server that
are specific to the operating system. For this reason, changing the operating
system can disable Storage Management.
To avoid this problem, you should uninstall Storage Management before
upgrading. If you have already upgraded without uninstalling Storage
Management, however, you should uninstall Storage Management after the
upgrade.
After you have uninstalled Storage Management and completed the upgrade,
reinstall Storage Management using the Storage Management install media.
You can download Storage Management from support.dell.com.
