Hi,

In SV2(2.1) we started doing VSM to vCenter server certificate validation.

You can find more info about this change in the SV2(2.1) Release Notes.

"If the certificate authentication fails, a warning is generated but the connection is not impaired. This is an optional feature."

HTH,

Is there any way to turn of this warning as we are not using any certificate in the vCenter?

Hi RK and Stanley,

 

This has been fixed in SV3(1.1). The defect ID is CSCuo39379.

 

The fix does two things:

1. Change the output of the message to be more detailed

2014 Jun 21 23:46:32 labVSM vms[3345]: %VMS-1-CONN_SSL_NOAUTH1: SSL AUTHENTICATION failure. [This message can be safely ignored if vCenter Certificate is not in use.]

2. Provide the option to enable/disable these messages

Cisco Nexus 1000V for VMware vSphere System Management Configuration Guide

 

Have a good day,

Joe
