If the Hostname and Name are not the same - in a cluster - there are issues

[yxeGithub]

Environment

• Declarative Onboarding Version: 1.42.0-9
• BIG-IP Version: 17.1.1

Summary

When a DO is sent to an HA pair that wasn't configured with DO - an error like this happens:
The requested system device (/Common/hostname.domain.com) was not found.

It seems there is some backend code that is using / assuming the hostname / Device Name are the same and it causes issues with DO.

The result is that it attempts to Rollback, and the system is left with a DO config in its local config DO also as verified by posting to: /mgmt/shared/declarative-onboarding/config

Steps To Reproduce

Steps to reproduce the behaviour:

1. Build an minimal HA Cluster - HA-VLAN, HA-SelfIP, Default Route, Trust, Config Sync - etc.
2. Deploy a basic DO

            }
        }
    }
}

Expected Behavior

I wouldn't think there needs to be a consistent Device Name and Hostname.
A POST'ed DO fails stating it cant find the hostname even though I posted the declaration to the Active Device's IP address.

Actual Behavior

POST fails with an error.

Further here is a snippet of the Get of the DO config post failure:
