The OS installation process is interrupted and the server is rebooted.
Determine the value set for the Watchdog Timer. The Watchdog Timer is a new feature in the BIOS of the C-series servers. If this feature is enabled and the value is set for a time duration that is less than the time needed to install the OS, then the OS installation process is interrupted. This Watchdog Timer feature automatically reboots or powers off the server after the specified time duration. Before you begin the OS installation process, disable the Watchdog Timer feature.
UCS-SCU displays the following message even after mapping the virtual USB or connecting the physical USB:

After installing the Windows operating system through UCS-SCU, Windows Device Manager displays some devices with a yellow bang.
This issue may result because of one of the following reasons:
The device may not be in the Cisco support matrix.
You may not have selected some device drivers in the SCU GUI.
Windows setup fails with BSOD 0x7B (inaccessible boot device).
You may not have selected the device driver for boot controller in SCU GUI.
CIMC change does not reflect in UCS-SCU immediately.
Changes made to virtual disks using CIMC may not be immediately viewable in the SCU user interface, if the server is booted with SCU. Reboot the server to synchronize with CIMC.
During the Power On Self-Test (POST), both LSI embedded MegaRAID and LSI 2008 controller are detected but only the LSI 2008 controller is viewed in the UCS-SCU.
Both LSI embedded MegaRAID and LSI 2008 are not supported together in the UCS-SCU. If you have both, then only LSI 2008 gets detected. Remove the controller for the LSI embedded MegaRAID to get detected.
