VM-FEX: Two UCS Instances Sharing Same DVS in vCenter
I need to have two Cisco UCS instances share the same set of distributed virtual switches in a VMware vCenter. According to the Cisco documentation, each instance must use the same extension key and certificate:
"If two Cisco UCS instances want to connect to the same VMware vCenter instance, they must use the same extension key and certificate.
Cisco UCS Manager generates a default, self-signed SSL certificate to support communication with a VMware vCenter. You can also create your own custom certificate to communicate with multiple VMware vCenters. When you create a custom certificate, Cisco UCS Manager recreates the extension files to include the new certificate. If you subsequently delete the custom certificate, Cisco UCS Manager recreates the extension files to include the default, self-signed SSL certificate."
No information is provided on how to create a custom certificate or how to get both instances to use the same certificate. Has anyone attempted this?
