fence_scsi device parameter update (addition/deletion) causes restart of all resources

Solution Verified - Updated -

Issue

  • Does it possible to create an independent fence_scsi device for every new resource group that is supposed to add/remove in future?
  • Each time an update on the fence_scsi device parameter causes a restart of all resources.
  • Do we have any other options in the fence_scsi configuration that can be used to avoid cluster-wide resource restart after updating fence_scsi configuration?
