CMMVC7205E The command failed because it is not supported.

Environment:

IBM FlashSystem 5030 (8.5.0.11) connected with FC to three Bare-metal OpenShift Nodes (4.15.19) with IBM block storage CSI driver operator installed (1.11.3)

Problem Description:

New LUNs get created on storage system, but not mapped to hosts. See errors in logs below.

Logs:

Configuration

Even though we have set environment CONNECTIVITY_TYPE = fc on the host-definer-hostdefiner, it seems the CSI still tries to make a connection to the LUN over NVMEoverFC and that obviously fails - since its not available in our setup. 🏴‍☠️
