Re-cache the network and storage driver directory
Verify that the drivers are in the drivers/kbe_windows_x86 or the drivers/kbe_windows_x64 directory before you re-cache.
NOTE: Re-caching drivers only scans the drivers share directory, not the drivers_postinstall directory.
1. On the left navigation bar, click Library to expand the section, then click Drivers to display the Drivers page.
2. Select Choose Action > Manage Drivers, and click Recache All Drivers. You can also select only the directories where changes were made to update the appliance faster.
