@ ScottK as per your TechNote ""Once VCS gets into this state, IMF registration for the particular resource does not succeed, unless the AMF driver is unconfigured and reconfigured.""

1.) What are the steps for "AMF driver is unconfigured and reconfigured". please share the steps.

2.) I have configured Application Resource start, stop and monitor process only. I feel that there are more steps to configure the AMF which I did not do thats why I am facing the ERROR.

===========================

I read the guide and see from Page # 229 under VCS Admin Guide (http://sfdoccentral.symantec.com/Storage_Foundatio...)

Extract:

Enabling and disabling AMF on a system
 

Enable or disable AMF as follows:
To enable AMF on a system
◆ Run the following command:
haimfconfig -enable -amf
This command sets the value of AMF_START to 1 in theAMFconfiguration file.
It also configures and loads the AMF module on the system.
To disable AMF on a system
◆ Run the following command:
haimfconfig -disable -amf
This command unconfigures and unloads the AMF module on the system if
AMF is configured and loaded. It also sets the value of AMF_START to 0 in the
AMF configuration file.

I think this above Extract answered of my question(s) ..So disable and re-enable can do:

""AMF driver is unconfigured and reconfigured."" as your suggested TechNote is saying (https://sort.symantec.com/search?q=V-16-10001-20565)  ..Right ?   :)
