Installing Operating Systems; Esxi Install - Cisco UCS User Manual

Installing Operating Systems

The unattended operating system installation function helps you install the Microsoft Windows and
RedHat Linux operating systems. UCS-SCU has integrated device drivers including RAID drivers to
seamlessly install operating systems on supported RAID logical arrays without additional load driver
steps or devices such as the USB.
UCS-SCU supports operating system installation only on virtual disks, and solid state disk (SSD) in
AHCI mode. Installation on physical disks is not supported. All UCS-SCU supported operating systems
are organized into three groups: Windows, Linux and RHEL.
Note
Before you begin the operating system installation, be sure that you have disabled the Watchdog Timer.
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, the operating system installation process is interrupted. This Watchdog Timer feature
automatically reboots or powers off the server after the specified time duration.
