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.
You can use the following two options to install the operating system:
The ESXi Install option allows you to install the operating system and customize the default settings.
Step 1 To enter the unattended operating system installation function area, click OS Install in the left navigation pane.
Step 2 Click the ESXi radio button and choose an ESXi version from the Operating System
drop-down list.
The Edition drop-down list appears.
The OS Install page of the selected ESXi version appears.
To configure the basic configuration settings, follow these steps:
Step 1 In the Basic Configuration area, do the following:
a. In the Root Password field, enter the root password.
b. In the Confirm Root Password field, reenter the root password.
c. From the Media Type drop-down list, choose the disk on which you want install OS. This can be one of the following:
Note A disk that is detected during SCU boot is listed under Media Type.
– Remote Disk—Refers to the SAN based FC or FCoE disk allocated on the target server.
– iSCSI Disk—This refers to SAN based iSCSI disks configured on the target server. If you choose this option, then review and update the following parameters:
Note iSCSI Disk is always listed under Media Type. If you choose iSCSI disk for OS installation, then you are required to enter the required input fields to discover the iSCSI target. To discover the iSCSI target, click Get Disks button.
Note When configuring iSCSI parameters in Cisco IMC, configure values for primary target only and leave the secondary target values blank. If you configure secondary target then ESXi installation will fail.
Note Installation of ESXi on iSCSI software targets are not supported through SCU.
d. From the Select Disk drop-down list, select the disk on which the OS will be installed.
The Network Settings allows you to enter the network configuration settings for the onboard network adapters that are detected by the operating system during installation. These settings do not affect the network settings for the Cisco IMC. We recommend that you set different IP addresses for the operating system and Cisco IMC. The network interface column lists each network adapter detected by the UCS-SCU. Your operating system may have a different name for the interface after you install the operating system.
Note Only one of the active network should be configured, and this network interface will be ESXi management network.
To configure the network settings, follow these steps:
Step 1 Click Network Settings to open the corresponding window.
The Network Settings window displays the link status of available network interfaces and the corresponding IP address, subnet mask, gateway, DNS, link status, vendor, type, and MAC address.
Step 2 To edit the Network Settings, do the following:

The Quick Install option allows you to quickly install the operating system with the default parameters. You can view the OS Install page with the default parameters depending on the target operating system. The Quick Install method does not require any user input and is a one-click operating system installation method.
To perform the quick installation of the OS, follow these steps:
Step 1 To enter the unattended operating system installation function area, click OS Install in the left navigation pane.
Step 2 Click any one of the operating system radio buttons.
Step 3 From the Operating System drop-down list, select the version of the operating system.
