iControlREST - adding members to a pool

Hi folks, I've come across an odd issue when trying to update an existing pool with new members.

First create a pool in your favourite way. I've used curl here but happens other ways too.

Do a GET on the pool members to ensure emptiness:

curl -k -u user:password -X GET -H "Content-Type: application/json" https://your.big-ip.net/mgmt/tm/gtm/pool/test-pool/members

Do a POST to the pool members to add a member(assuming you have already created the server/virtualserver):

curl -k -u user:password -X POST -d ‘{ "name": "test-server:test-virtualserver", "fullPath": "/Common/test-server:test-virtualserver" }’ -H "Content-Type: application/json" https://your.big-ip.net/mgmt/tm/gtm/pool/test-pool/members

I am receiving the response:

 

{
    "code": 404,
    "message": "Object not found - test-server:test-virtualserver",
    "errorStack": []
}

 

When I do a GET on the members I expect emptiness, no?

curl -k -u user:password -X GET -H "Content-Type: application/json" https://your.big-ip.net/mgmt/tm/gtm/pool/test-pool/members

Actual Response is that the member got added:

 

 {    "kind": "tm:gtm:pool:members:memberscollectionstate",
      "selfLink": "https://localhost/mgmt/tm/gtm/pool/test-pool/members?ver=11.5.3",    
      "items": [        {            
        "kind": "tm:gtm:pool:members:membersstate",            
        "name": "test-server:test-virtualserver",            
        "partition": "Common",            
        "fullPath": "/Common/test-server:test-virtualserver",            
        "generation": 212,            
        "selfLink": "https://localhost/mgmt/tm/gtm/pool/test-pool/members/~Common~test-server:test-virtualserver?ver=11.5.3",            
        "enabled": true,            
        "limitMaxBps": 0,            
        "limitMaxBpsStatus": "disabled",            
        "limitMaxConnections": 0,            
        "limitMaxConnectionsStatus": "disabled",            
        "limitMaxPps": 0,            
        "limitMaxPpsStatus": "disabled",            
        "monitor": "default",            
        "order": 0,            
        "ratio": 1        
        }    
        ]} 

 

Am I doing something wrong here? How do I avoid the HTTP 404 on the POST?
