CMDB Simulator Task 09: Configure Reconciliation Rule

[MGHandy]

I have been working through the self-paced CMDB Fundamentals course on NowLearning, I am stuck on the Configure the CMDB Simulator (Rome) > Task 09: Configure Reconciliation Rule.

It appears i may not be understanding something simple or there just isn't enough information given (which might be rather unlikely).

The requirement states:

Being part of the Cloud Dimensions CMDB implementation team, using CI Class Manager, you are tasked to update the Windows Server class with a reconciliation rule that achieves the following:

- Windows Server record in CMDB with discovery source LANDesk CAN be updated by discovery source ServiceNow

- Windows Server record in CMDB with discovery source ServiceNow CANNOT be updated by discovery source LANDesk

I have made rules where servicenow has priority over landesk to update all attributes where discovery source is servicenow OR landesk

I have created rules where landesk has priority over servicenow to update all attributes where discover source is NOT landsek.

I have taken each bullet above literally and made a rule specifically for what each says.

I have spent a total of almost three hours on this one simple little thing coming up with rules for everything in between and including the above. nothing appears to validate correctly. I don't know what i'm missing.

Can someone help me out. I don't necessarily want the answer, just help understanding what requirements are asking.

Per the information in Create CI Reconciliation Rule "After an authorized discovery source updates an attribute, subsequent updates are accepted only from the same discovery source or from a discovery source with a higher priority...." 

Your rules repeated below will both be inherently true if the discovery source ServiceNow prescience is set higher than LANDesk within a reconciliation rule. 

• "Windows Server record in CMDB with discovery source LANDesk CAN be updated by discovery source ServiceNow"
• "Windows Server record in CMDB with discovery source ServiceNow CANNOT be updated by discovery source LANDesk"
  

Therefore ServcieNow[100], LANDesk[200], all attributes, no filter.

I did the following and I succeeded in task 011 as well

The first reconciliation rule is:

and no filter condition

the second reconciliation rule is almost the same as first. The difference is that you include all atributtes (second step).

Once you do it, you run the scripts in the order (script from task 10 and after task 11). 

Validate and be happy!

I hope it helped!

I had to do this to ge trough..  The rule has no conditions, and applies to all fields is my understanding too...

Hello,

May I seek help with Task #09. I already did the following but to no avail. Hope you could check. Thank you!
