Hi All,
I would like to understand the details of ServiceEnabled attribute in Task Service URI
Assume many tasks was created and running when ServiceEnabled attribute was true.
When user Patches ServiceEnabled as false in Task Service URI, what will happen to all task created earlier?
Do we need to delete all tasks created?
If user request for Get task Instance, what needs to be responded when ServiceEnabled as false in Task Service URI

Thanks,
Mani

The short answer is that you shouldn't make the ServiceEnabled property read-write. Just have it as a read-only property (which is allowed for any read-write property in Redfish - the Service implementation doesn't have to allow write access). That was probably a mistake in our definition, but we were trying to be consistent with other "Services" being modeled in Redfish - to be able to turn the service on/off using that property.

The Task service, though, is an 'internal' service for the Manager / Redfish Service to utilize, allowing a user to disable it would not make sense...

Hi,

So can I consider that all ServiceEnabled in every Service that under redfish/v1 can follow this rule?
Ex:
The ServicedEnabled under (1)/redfish/v1/EventService (2)/redfish/v1/SessionService (3)/redfish/v1/AccountService and more...

Thanks,
Archer.

The "rule" is that the service can always implement a read-write property (as defined in schema) as read-only. That is not a global recommendation about allowing a "service" to be disabled...

While allowing a user to disable the SessionService probably doesn't make sense - there are certainly good reasons (a poorly handled event storm) that an admin might want the ability to temporarily disable the EventService.
