Environment

Version: 20.4, 23.4
Component: cisco_ucs 2.52

Resolution

Update cisco_ucs probe to 2.54.

Additional Information

In the above scenario, the end user was upgrading the fabric interconnect via the methodology defined by Cisco, which is to replace one fabric interconnect at a time. As part of this upgrade, they had to also updated the UCSM package to 4.16, and then ultimately to 4.20. This problem may not be present in systems that were not upgraded in this fashion.
