Resolution
The issue occurs because the agent name is mismatched between the agent machine and the AM server side.

To resolve it, there are two options that can be performed.

Option 1
  1. Comment "RSA_AGENT_NAME" in the rsa_api.properties file (when this line was commented out Agent SDK will use it's hostaname as the agent name).
  2. In Security Console, modify that agent record and change its name to the hostname of the agent machine.
    For example: if the Agent machine's hostname is "agentA.emc.lab" then you need to change the agent name in security console to "agentA.emc.lab" instead.

Options 2
Uncomment and give a value to "RSA_AGENT_NAME" in rsa_api.properties file. Then, in Security Console give the same name to that agent record.
For example: You give the value of "RSA_AGENT_NAME" in rsa_api.properties as "AgentA",  then, in Security Console, you need to set the agent record name to: "AgentA"  as well.
