This is a result of the Solaris Verified Boot. Verified Boot refers to the verification of object modules before execution using digital signatures.If enabled, Solaris Verified Boot checks the factory-signed signature in a kernel module before loading and executing the module. This is to detect accidental or malicious modification of a module. The action taken is configurable and, when enabled, will either print a warning message and continue loading and executing the module or will fail and not load and execute the module.
The WARNINGS do not prevent Veritas modules from Loading so can be safely ignored.
