You can only uninstall a permanent license that is not in use. If you try to delete a permanent license that is being used, Cisco UCS Manager rejects the request with an error message.
If you attempt to use a port that does not have an installed license, Cisco UCS initiates a grace period. The grace period is measured from the first use of the feature without a license and is reset when a valid license file is installed. After the grace period expires, the ports are not functional. Contact your Cisco representative for information about the length of the grace period for your fabric interconnect.
Permanent licenses cannot be uninstalled if they are in use.
The following example shows the uninstallation of port9.lic:
UCS-A # connect local-mgmt
Cisco UCS 6100 Series Fabric Interconnect
