Description Renich Bon Ciric 2023-05-03 18:59:36 UTC 
Description of problem:
A freshly installed RHOSP 16.2 when integrated to a Dell PowerStore, fails to delete volumes. Creation and attachment work fine. 

Version-Release number of selected component (if applicable):
cinder-volume-16.2.5-3

How reproducible:
* Deploy RHOSP 16.2
* Integrate it with the Dell PowerStore solution. Use this for reference: https://github.com/dell/osp-integration/tree/master/osp-deploy/cinder
* Create a volume using cinder (works).
* Try to delete it. (fails)

Steps to Reproduce:
1. Deploy RHOSP 16.2
2. Integrate it with the Dell PowerStore solution. Use this for reference: https://github.com/dell/osp-integration/tree/master/osp-deploy/cinder
3. Create a volume using cinder (works)
4. Try to delete it. (fails)

Actual results:
We get a "deletion failed" message.

Expected results:
The volume should be deleted without issue. 

Additional info:

This is the error we found in cinder-volume's logs:
