Description of problem:

Cannot dis-associate a Subnet from a Domain using Hammer.

- Due to which can not delete a Subnet using hammer command

Version-Release number of selected component (if applicable):

Satellite Server v.6.1.6

How reproducible:

Steps to Reproduce:

1. Create a Domain and Subnet using hammer command:

# hammer domain create --name "test-domain"
Domain [test-domain] created

# hammer subnet create --name "test" --network "x.x.x.x" --mask "255.255.255.0" --domains "test-domain"
Subnet created

2. Try deleting the subnet and it will fail with the below error :

# hammer subnet delete --name "test"
Could not delete the subnet:
  test (x.x.x.x/24) is used by test-domain

# hammer domain delete --name "test-domain"
Could not delete the domain:
  test-domain is used by test (x.x.x.x/24)


Actual results:

Could not delete the subnet:
  test (x.x.x.x/24) is used by test-domain

Expected results:

Subnet Deleted successfully

Additional info:

It is due to the association created between the Subnet and the Domain.

If a Subnet is created without the Domain association, then it is deleted successfully.

Currently we can remove the association manually over the Satellite Server Web UI

--> log in to Satellite --> Infrastructure --> Subnet --> Select the Subnet "test" --> Domains --> Remove the check mark from "test-domain" --> Submit

# hammer subnet delete --name "test"

- Below Hammer command does not remove the association using hammer command:

# hammer subnet update --domains "" --name "test"  ---> Rather it associates the Subnet with all the Domain's.
