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 as cluster communications are enabled by default on all network
adapters and USB NIC IPv4 addresses cannot be used to communicate externally, thus disrupting 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.
Acceptance Failed to save: Dell EMC Software License Agreement and
Customer Notice
Cause: Dell EMC Software License Agreement and Customer Notice acceptance may fail to save. This may happen when you
launch multiple instances of the Dell EMC OpenManage Integration extension from the same gateway, and accept terms and
conditions in one instance. In the remaining instances, if you attempt to accept the terms and conditions, you will encounter this
error.
Resolution: Navigate away from the Dell EMC OpenManage Integration extension where this issue occurs, and then back in to
resolve this issue.
Can I use the Single Sign-on or smart card authentication to log in to
OMIMSWAC?
You cannot use Single Sign-on or smart card authentication to log in to OMIMSWAC. To connect to a cluster/server, use
'manage as' and then enter domain or gateway admin credentials.
Why am I not able to access the OMI extension using remote connection?
Without gateway administrator privileges, you will not be able to access the OMIMSWAC. You can launch the browser and
connect to the gateway system using gateway administrator credentials from the remote workstation.
