How does AMDB to/from CMDB CI updates happening

[tshk]

I would like to understand how CMDB to/from AMDB CI updates are happening.

There is a requirement for me to delete CMDB CI's but that shouldnt affect AMDB CI;s - how do i achieve and what is the impact analysis i should do before it tampers the production

P.S : we are running discovery to insert/update CI's

Also in one of my earlier experience when we tried deleting CI's it did not delete the references properly - after truncating table we saw some number in no of records but the list looked empty.

The asset record and the CI records are kept synchronized with two business rules:

• Update CI fields on change
• Update Assets on change

Assets and CIs share certain fields. While modifying any of the shared fields on the asset or CI record, the same field on the other record is automatically updated with these business rules.

As the asset and CI records are linked then deleting the CMDB CI will delete the asset record as well.

What is the use case of deleting the CMDB CI?

Additionally, check under Asset > Administration

• Asset-CI Field mapping
• Asset-CI install status mapping
• Asset-CI hardware status mapping

These sections contain the directional mapping between the linked fields of CMDB and AMDB.

The requirement is, for certain assets like printer, Computers when i import to assets it shouldnt create/update the CI. But when it discovers it should update the assets.

Management needs only infrastructure assets to be created as CI

What do you want to achieve at Import then... only updating the printer, computer etc., CIs?
