Configuration of relationships between CI's

[Riya25]

How to find if downstream and upstream relationships of a CI is right or not.

And currently there are CIs for which downstream Relationships contain same switches for all objects across the Globe.

How to find the root cause of this?

Thanks in advance.

You'd need to check the data sources you have setup, but also check the CI relationship table as well.

Once you check that, you'd need to talk with the SME's that are running that operation to make sure what you have matches with what they have.

Hi,

We have a suggested relationship table which shows you how CI are related in both upstream and downstream directions. If you are using discovery and service mapping the ServiceNow make use of this table and CI relationship types table.

Now why you have them wrong may be because of many reasons like:

1) As MB said Data source.

2) Human error or manual upload's

Please check those how they are created and who is the user who created those.

Thanks,
Ashutosh

Hi Riya, 

I think it's important to understand that upstream/downstream only reflect the relationship type in the CMDB.

If you look at the cmdb_rel_ci table, you'll have a parent and child CI. From the context of a given CI, its parents are considered upstream by nature of this table relationship.

Similarly, a CI's children are considered downstream solely because of the way this relationship is defined.

Mark it correct and helpful if applicable.

Thanks and regards,

Hello all,

Thank you for all the responses.

I further need to highlight this.

if 2 CI's are in different location/zones,then how it is possible to have a relationship between them.

For ex-CI is  "POL-MAL-ESX001" (ESX Server) is in zone -EMEA and other CI "WTZ-AM-ASHBURN-CORE" (ip switch) is of America.Then how are they linked together.

 "WTZ-AM-ASHBURN-CORE" is a child of "POL-MAL-ESX001".

And there are more CI's from different zones having "WTZ-AM-ASHBURN-CORE" as their child.

Can somebody please help me to solve this.

Thanks in advance!!
