Solution Verified - Updated -

Issue

  • We have an HA cluster with shared host-based mirrored disks
  • The multipath config default is "1 queue_if_no_path" which is good for all disks except for the set of mirrored disks
  • Is there a possibility to have on lun-bases a different features in multipath.conf, or is there a possibility with udev?.

Environment

  • Red Hat Enterprise Linux (RHEL) 5, 6
  • device-mapper-multipath 0.4.9
