Hardware Requirements
Note Some LSI RAID controllers take time to complete the operation during RAID configuration. SCU does
not have any control over this issue. As a workaround, you can either recreate the RAID or wait for the
operation to complete.
Hardware Requirements
The following are the minimum hardware requirements for UCS-SCU:
• CD-ROM drive—A USB CD/DVD-ROM drive is required to be able to boot and run the UCS-SCU.
You can also use the virtual media option in the CMC KVM to boot UCS-SCU.
• Mouse—Some functions require a standard mouse (PS/2 or USB) for navigation.
• USB disk on key device—Functions such as saving UCS-SCU logs require a USB disk on key.
• RAM—A minimum of 1 GB RAM. If the available RAM is less than the minimum recommended
value, UCS-SCU will not function properly.
• Network adapter—Some optional functions, such as, downloading the OS drivers from
support.cisco.com, require network access. Any single onboard NIC adapter connection is
supported.

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.
You can use the following two options to install the operating system:

Automatic Setup without Redundancy
Automatic setup without redundancy requires one or more hard drives. UCS-SCU creates RAID 0 with
this option.
Note This option does not work, if number of HDDs are more than thirty-two.
Table 7-3 shows the default values that are displayed for automatic setup without redundancy.
Table 7-3 Default Values for Automatic Setup without Redundancy
Parameters Values
Controller MegaRAID SAS <family>
RAID Level 0
Stripe Size 64
Read Policy No Read Ahead

Note The common parameters, except for total size, are the default values for the controller.
Automatic Setup with Redundancy
Automatic setup with redundancy is the default RAID configuration option. This configuration requires
at least two physical drives to be available. If two physical disks are not available, the default RAID
configuration would be automatic setup without redundancy.

Troubleshooting
This chapter lists various troubleshooting options available when using the UCS-SCU application.
UCS-SCU Issues and Solutions
• 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:
No USB Disk on Key detected
CHAPTER
8
–
For USB devices mapped through vmedia, try selecting the USB reset from the vmedia GUI
(virtual media session -> details -> USB reset)
–
For a physical USB device, check the vendor and product information or try a different device.
• After installing Windows OS, the KVM mouse does not work and Windows Device Manager
displays a yellow bang for the USB human interface device.
Check the version of CMC. Ensure that you have the latest version of CMC installed on your server.
• Windows installation fails and the following message is displayed:
Selected disk has MBR partition table. On EFI systems, Windows can only be installed to
GPT disks.
The EFI CD ROM device for the virtual drive was used to boot the Windows 2008 image. Use the
CD ROM device from BIOS CD ROM order.
• After installing the Windows operating system through UCS-SCU, Windows Device Manager
displays some devices with a yellow bang.
–
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.
• CMC change does not reflect in UCS-SCU immediately.

UCS-SCU Issues and Solutions
Changes made to virtual disks using CMC may not be immediately viewable in the SCU user
interface, if the server is booted with SCU. Reboot the server to synchronize with CMC.
• 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.
• SCU inventory is impacted
Check to see if the server has a USB drive with GPT partition plugged-in. If so, either remove the
USB drive and reboot to SCU or use/re-format the USB stick with non-GPT partition.
• OS installation fails on the interactive and non interactive SCU
If the virtual disk size is greater than 2 TB, OS installation fails and the following message is
displayed:
Unable to install OS.
Create a virtual disk with a size lesser than 2 TB.
