Afdter looking at the logs I see a number of

ERROR os_brick.initiator.connectors.nvmeof [None req-09f091dc-0934-4609-8e7e-cfdca70d5fea 268785dd82794839ba2ff15fc962c0a6 a17cd616f3094b89bbb0a201a8a8a9b2 - - - -] Could not connect to Portal tcp at 10.136.194.68:4420 (ctrl: None): exit_code: 1, stdout: "", stderr: "already connected#012",: oslo_concurrency.processutils.ProcessExecutionError: Unexpected error while running command.

These look to be the root cause, as the Pure cinder driver is doing exactly what it is supposed to be doing, with regards to managing the volume and host connections for the FlashArray on the host.
