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. Learn more about how Cisco is using Inclusive Language.
This chapter lists various troubleshooting options available when using the UCS-SCU application.
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.
– 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.
Check the version of Cisco IMC. Ensure that you have the latest version of Cisco IMC installed on your server.
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.
– The device may not be in the Cisco support matrix.
– You may not have selected some device drivers in the SCU GUI.
You may not have selected the device driver for boot controller in SCU GUI.
Changes made to virtual disks using Cisco IMC may not be immediately viewable in the SCU user interface, if the server is booted with SCU. Reboot the server to synchronize with Cisco IMC.
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.
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.
