The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

If you are installing Windows on a SAN LUN, you must install Cisco VIC drivers for Windows during the OS installation. If you do not provide the drivers during the OS installation, the system is not able to detect the SAN LUN.
Except in Cisco UCS M-Series, if installing Windows on the local hard disk, it is not required to install the drivers during the OS installation. You can install the drivers after completing the OS installation.
Cisco UCS Manager Release 3.1(2) and later releases do not support Cisco UCS M-Series Servers.
In Cisco UCS M-Series, to install Windows on the local hard disk, you must install the VIC drivers during OS installation.
Caution | The driver installation file modifies certain registry entries, such as the disk timeout value of the system disk driver. Removing the driver does not restore these values. |
Caution | Failure to adhere to the proper upgrade sequence can cause the server to crash. |
