Resolution

Steps to Resolve

For VCF 9.1 and higher

Recommended Action:

1. Run local API command "curl -X GET http://localhost:7440/nsxapi/api/v1/mirror-sessions" to get all sessions on manager node. If the "_create_user" is not "nsx_policy", it means this session can not be upgraded to Policy mirror session.
2. Check the backed up MP mirror sessions, which name with prefix PortMirroringSession in path /var/log/proton on manager node.
3. Compare the results of Step 1 (as target) and Step 2 (as source) to identify the sessions that failed to upgrade:
   • In target result, if the MP mirror sessions are upgraded to Policy mirror sessions successfully, the "display_name" of the policy mirror session will use the original MP mirror session name as a prefix, followed by eight random characters. Additionally, the "_create_user" field will appear as "nsx_policy".
   • In target result, if the "display_name" is still the original MP mirror session name or "_create_user" is not "nsx_policy" in target result, it means this session is not upgraded to Policy mirror session. Run local API command "curl -X DELETE http://localhost:7440/nsxapi/api/v1/mirror-sessions/<session-id>" to delete un-upgraded MP session on manager node, where the <session-id> value is retrieved from target result.
   • If the session is not in the target result, it means the session is deleted. It does note need to be deleted again; just need to manually create it.
4. Based on the results of Step 2, manually create the corresponding Policy mirror sessions which MP mirror session is failed to upgrade.
