CMDB Operating System choice list diminishes through extended tables

Todd8 · ‎09-19-2018

Hello, I am failrly new to servicenow CMDB and have a question regarding the choices available when manually entering CI's. Whilst automated discovery is working quite well I've had to manually enter machines in a DMZ until I can get discsovery working in there. I can see using the CI Class Manager that 'Computer' in the hierarchy lists all available operating systems, but as I navigate to 'Server' then 'Windows Server' the list of operating systems available in the choice lists diminishes and I no longer have the lastest OS's to choose for my manually entered CI's. There's clearly someting that is filtering or qualifiying the choice list down when I manually select the correct class for the server. Is someone able to explain what is going on here?

Thanks, Todd.

And they should! Seems like someone may have mucked with the works. The attribute 'os' starts at cmdb_ci_computer and is available to all extended classes. You might ask your platform admins to see if they put any restrictions on that field to lower classes and if not, open an incident with support. But what you're doing does work OOB, just gotta find the gremlin..

Hi pingu6245,

No I haven't however, I'm still looking for a solution and our company has engaged the services of ServiceNow partner which I will hopefully be able to work through a solution with. If I get a resolution I'll post here.

I am looking at ServiceNow's out of the box developer's instance for London. The Value choices for the cmdb_ci_computer table where the Element field is "os" are older versions of the Windows and Windows Server operating systems including "Windows 2000 Professional" and "Windows XP". There are other non-Windows operating systems listed as well. The more recent versions such as "Windows 10" and "Windows Server 2016" are not in this OOTB table. Is this expected behavior? I am not sure if this is related to the originally posted issue, but it is similar.

I found this discussion because I was trying to figure out why my company has a customized choice list for computer operating systems.

I am running into the same issue on Madrid. I cannot find what is causing this. Were you able to resolve this? If so, please share. Thanks.
