Fencing fail on Red Hat Cluster Suite when using HP's iLO3 ?

Solution Verified - Updated -


  • Sometimes we get following errors on the cluster nodes when a fence is initiated and the host fails to get fenced:
fence_localhost1_iLo3_monitor_60000 on itmu-localhost-cl1 'unknown error' (1): call=135, status=Error, last-rc-change='Mon 13:40:13 2014', queued=1175ms, exec=0ms

Error: Received an Unexpected RAKP 2 message
packet session id 0x0 does not match active session 0xa0a2a3a4
ipmitool: lanplus.c:1167: read_session_data_v2x: Assertion `0' failed.
  • The fence device have been configured properly on the cluster nodes.
  • What is causing such problem to appear?


  • Red Hat Enterprise Linux (RHEL) 6.5 (High Availability Add On)
  • Red Hat Pacemaker cluster.
  • HP iLO3 fence devices.
