Description Thomas Hennessy 2016-05-10 20:24:19 UTC

Description of problem:Customer is asking how to use automate to delete a host instance from the VMDB.


Version-Release number of selected component (if applicable): 5.5


How reproducible: This is a question for which I can find no answer or example in any existing automation documentation


Steps to Reproduce:
1.
2.
3.

Actual results:


Expected results:


Additional info:
Use Case provided by customer:
"We have a automated process to provision a host. So, before provisioning a new host we want to check if there is any host with that name in the VMDB. If it exists want to remove that automatically. This is required in a case where provisioning is failed and we had to rebuild the host."

John - I would like to clarify that this enhancement is only asking for the ability to delete the instance in the VMDB and that it does not include any provider level calls to delete a host defined in on a provider (ext_management_system).

Comment 7 Milan Falešník 2017-11-03 10:39:57 UTC

Verified in 5.9.0.5.

$evm.vmdb(:Host).all.last.remove_from_vmdb works as expected.
