Greater number of SCSI reservation keys over the devices which are part of RHEL Pacemaker cluster configured with `fence_scsi` agent

Solution Verified - Updated -

Issue

  • The SCSI disk shows more reservation keys than expected where it should have less number of keys.
  • In a VMWare VM associated with RDM device, the SCSI reservation keys count is greater than the expected value. Is this expected?

Environment

  • Red Hat Enterprise Linux 7, 8, 9
  • VMWare VM with RDM disk
  • SPC-3/SPC-4 devices
