Issue/Introduction

You are trying to delete a deployment on any of these methods:

• using bosh command : bosh -d <your-deployment> delete-deployment
• using cf cli where an on demand service is backed with a bosh deployment : cf delete-service-instance <your-service-instance>
• using tkgi command: tkgi delete-cluster <cluster-name>

The commands will fail with a similar error below

Using environment '10.52.31.147' as client 'ops_manager'

Resolution

This error is thrown due to deployment containing a vm that was deliberately ignored meaning the command below was executed previously  
 

bosh -d <service-instance-deployment> ignore <vm>

You can check if a vm is ignored using 
 

bosh -d  <service-instance-deployment> instances --details

check the column ignore and see if this is set to true

If a vm is marked as ignored any bosh command on this vm will be ignored. For more info, please see doc .
bosh director won't let you delete a deployment if one of the vm on the deployment is ignored.

To resolve this simply unignore the ignored vm
 

bosh -d <service-instance-deployment> unignore vm

The command above tell bosh director to include this vm to be affected by bosh commands. For more info on unignore, please see doc. 

Then retry deleting the deployment.
