8.1 General description for policy management procedures

There are two kinds of management procedures. The first kind includes those operations that allow the NM to invoke policy management operations towards the EM.

  • Policy Creation
  • Policy Deletion
  • Policy Update
  • Policy Query
  • Policy Activation
  • Policy Deactivation

The second kind includes the operation that the EM notifies NM policy conflicts found in EM.

  • Policy Conflicts Notification.

8.2 Policy Creation

After the NM (IRP Manager) decides to create a policy (ies), it will send the create request to the EM (IRP Agent).

8.3 Policy Deletion

After the NM (IRP Manager) decides to delete a policy (ies), it will send the delete request to the EM (IRP Agent).

8.4 Policy Update

After the NM (IRP Manager) decides to update a policy (ies), it will send the update request to the EM (IRP Agent).

8.5 Policy Query

After the NM (IRP Manager) decides to query a policy, it will send the query request to the EM (IRP Agent). For the query request, the EM (IRP Agent) sends back the response with the policy to the NM (IRP Manager).

8.6 Policy Activation

After the NM (IRP Manager) decides to activate a policy (ies), it will send the policy activation request to the EM (IRP Agent).

8.7 Policy Deactivation

After the NM (IRP Manager) decides to deactivate a policy (ies), it will send the policy deactivation request to the EM (IRP Agent).

8.8 Policy Conflicts Notification

When the EM (IRP Agent) receives new or updated policy (ies) from NM (IRP Manager), it will check whether the each received policy is conflicts with the previous storage policy. If the conflict is detected, the EM (IRP Agent) will notify the information to the NM (IRP Manager).
