Chapter 8 Troubleshooting
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.
