Using an asynchronous task | Creating UCS File

Hi, I am trying the following REST URL to create a task to generate a UCS File: Method: Post URI: mgmt/tm/task/sys/ucs/ Body: { "command": "save",    "name": "UCS01" } So, I get back: {...

     ; to close the loop on this one, it appears that you the part that was missing in your request is the -X PUT request, to set the state to 'VALIDATING'

     

    # curl -k -u admin:admin -H 'Content-Type: application/json' -X PUT -d '{"_taskState":"VALIDATING"}' https://localhost/mgmt/tm/task/sys/ucs/1563478591515657?ver=12.1.3.4
{
    "code":202,
    "message":"Task will execute asynchronously.",
    "errorStack":[]
}

    That is the request which is necessary to cause any task to begin processing. Until then, the task is waiting for any number of additional tasks to be added together.

Hi,

Tested on v15.0.0 looks OK for me.

What BIG-IP version are you trying to?

curl -k -u admin:admin  -X POST -H 'Content-Type: application/json'  -d '{ "command": "save", "name": "UCS01" }' https://localhost/mgmt/tm/task/sys/ucs
 
{
  "_taskId": 1563470408202544,
  "_taskState": "STARTED",
  "_taskTimeInStateMs": 0,
  "_taskResultLink": "https://localhost/mgmt/tm/task/sys/ucs/1563470408202544/result?ver=15.0.0",
  "selfLink": "https://localhost/mgmt/tm/task/sys/ucs/1563470408202544?ver=15.0.0"
}
curl -k -u admin:admin -H 'Content-Type: application/json' -X PUT -d '{"_taskState":"VALIDATING"}' https://localhost/mgmt/tm/task/sys/ucs/1563470408202544
 
{
  "code": 202,
  "message": "Task will execute asynchronously.",

}

      Buddy, It works for me on v12.1.3.4.

      So, if you can save UCS from another way, we can't confirm issues during save the file.

      It sounds strange to me 😞
