      Description of problem:
      We need to change the behavior of the VM when it encounters an IO error to report. Currently, the default and only behavior is to pause the VM.

      openshift-pipelines-operator-rh.v1.11.0 Red Hat OpenShift Pipelines 1.11.0 Succeeded

      How reproducible:
      100%

      Steps to Reproduce:
      1. Map an iscsi LUN from the Netapp Storage Provider to 3 worker nodes
      2. Create a PV referencing the iscsi LUN and detailing the 3 worker nodes
      3. Create a shared PVC based on the iscsi LUN with volumeMode block and accessMode ReadWriteMany
      4. Create 3 Windows12 R2 vms each with their own OS disk and referencing the 2nd shared iscsi LUN based PVC
      5. Install the virtio-win-guest-tools to update the drivers on each of the VMs
      6. Via Disk Manager access the iscsi LUN, create a partition on all available space and install NTFS
      7. Install Windows Shared Cluster software on each of the 3 Windows VMS
      8. Install and configure Active Directory/DNS Domain Controller on one of the VMs
      9. Run the Failover Cluster - Validate Configuration tool and select to run only the Storage - ISCSI Reservation Test
      10. During the scsi3 persistent reservation REGISTER AND IGNORE EXISTING the node/vm accessed crashes with the error:
      "Failure issuing call to Persistent REGISTER AND IGNORE EXISTENT on Test Disk 0 from node xxxxx.."

          • Directly connecting 3 stand alone(Non Openshift Virtualization) bare metal machines installed with Windows to the same Netapp iscsi LUN and running the same failover validation tool with the scsi3 reservation tests works fine
          • This happens on multiple clusters using a different NetApp. And that it has also been tried with a RHEL 9 system presenting the iSCSI targets.

      Actual results:
      The scsi3 persistent reservation REGISTER AND IGNORE EXISTING test fails and crashes the target Windows node

      Expected results:
      The scsi3 persistent reservation REGISTER AND IGNORE EXISTING test should pass not crash the target Windows node
