Unable to Delete Azure SCOM Managed Instance Due to Internal Error

Question

Unable to Delete Azure SCOM Managed Instance Due to Internal Error

Oversight Operations 0

I successfully installed SCOM Managed Instance (MI) in Azure. However, when it was time to delete multiple resource groups supporting this project, I did not perform the deletions in the correct order. This may have caused the SCOM MI to generate an internal error, when cleaning up.

Steps Taken:

Attempted to force deletion of the resource using Cloud Shell.

Deployed the resource with --complete using a empty template.json file to remove the SCOM MI.
Validated the deletion of the resource group, but there is no force checkbox to perform the deletion.

Issue: Despite these efforts, the SCOM MI continues to generate an internal error, and I am unable to delete the SCOM MI resource and its resource groups.

Request: I need assistance in resolving this issue and successfully deleting the resource groups and SCOM MI.

Hello Oversight Operations,

Please refer to the below doc, which can help understanding the procedure to delete an SCOM MI.

https://learn.microsoft.com/en-us/azure/azure-monitor/scom-manage-instance/scom-managed-instance-faq#what-is-the-procedure-to-delete-an-instance-

And make sure there are no dependencies preventing the deletion. this could include linked resources or active monitoring solutions that rely on SCOM MI. such as, SQL Managed Instance, Key vault, the network firewall, Azure and internal GPO policies etc.

Once everything is clear then perform the deletion operation.

I have validated on my end no dependencies exist (e.g. key vault, network, AD GP. The only resource exist is the SCOM MI. What are the next steps.

Hello Oversight Operations,

Is it possible for you to share the error details and the SCOM MI version ?
And also, please confirm whether initially are you trying to delete it from SCOM instance view or from the Resource group?

If not, please give a try to delete the SCOM Mi from RG.

Please let me know the results.

Hi,

I was able to successfully remove the SQL MI and its separate resource group. The attempt to delete the SCOM MI and from its RG was also performed with failure which is the original request is how to force to remove it and RG both won't work. Again no SQL MI, AADDS, and network devices (e.g. NAT gateway, snet, and vnet) exist.

Here is the json failed logs: with masked ids

Answer 1

Firstly, you can delete an instance directly from the overview of SCOM or you can visit the resource group and check the location of SCOM, delete it from there.

After deleting the instance, you will also need to remove the two databases created in SQL MI. In the resource view, locate and select both databases (based on the name assigned to your SCOM Managed Instance) and click on Delete. The same procedure is clearly detailed in the MS Doc.

If still the issue persists, you can try using Az CLI az resource delete command as shown below.

az resource delete --ids "Resource ID of SCOM MI"

Also, check if there are any resource locks that is disrupting the SCOM MI resource deletion.

Hope this helps.

Oversight Operations, Can you try deleting the entire resource group once with Az CLI command by adding force deletion types flag.

Reference: az group delete

az group delete --name RGNAME [--force-deletion-types "provide the SCOM MI resource type]"
