Information.

We asked customer to reach out to the NETAPP and Netapp  shared the patch: https://review.opendev.org/c/openstack/cinder/+/951485 and asked RH to provide the hotfix. 

Discussed with engineering in slack thread[1] and there is hotfix for that planned in RHOSO-18 and for 17 to backport, the request should come from Netapp.
https://redhat-internal.slack.com/archives/C04GLFJE57Y/p1749084810914089

But this was opened to get how better we can assist as TAM: Vishal Sharma reached out to cinder engineering for help and seek support help to open a Jira.
