• The DUP may fail when attempting to downgrade a driver component to a lower version. In this case, uninstall the driver from the
operating system then rerun the component update from OMIMSWAC. For more information about how to uninstall drivers, see
Microsoft document.
Alternatively, you can also try the followings:
• Reset and update the iDRAC to version 4.20.20.20 or higher and then rerun the update. For more information about how to Reset or
update iDRAC, see iDRAC documentation.
• Run the update manually in the target node by downloading from the path specified in <Windows Directory>\Dell
\UpdatePackage\log\<Package Name> in the DUP log. Example for a network firmware is https://downloads.dell.com/
FOLDER06091050M/1/Network_Firmware_TWFF6_WN64_16.26.60.00.EXE.
• Ensure that the selected DUP is supported on the selected operating system and platform by searching the component name in the
Dell Support site. Dell support site URL: https://www.dell.com/support/home/in/en/inbsd1/?app=products.
Test-Cluster fails with network communication errors
Cause: With USB NIC enabled in iDRAC, if you run Test-Cluster command to verify the cluster creation readiness or cluster health, you
may see an error in the validation report. The error states that the IPv4 addresses assigned to the host operating system USB NIC cannot
be used to communicate with the other cluster networks. This error can be safely ignored.
Resolution: Disable the USB NIC (labeled as Ethernet by default) temporarily before running the Test-Cluster command.
USB NIC network shows as partitioned cluster network
Cause: When the USB NIC is enabled in iDRAC, cluster networks in the failover cluster manager show the networks that are associated
with the USB NIC as partitioned. This issue occurs since the cluster communication is enabled by default on all network adapters and USB
NIC IPv4 addresses cannot be used to communicate externally, therefore, breaking cluster communication on those NICs. This error can
be safely ignored.
Resolution: Disable cluster communication with the networks associated with the USB NICs from the cluster manager.
