Applies to

  • ONTAP
  • VMware ESXi

Issue

  • Periodic datastore disconnections.
  • Datastore corruption may occur.
  • Generally impacts Datastores shared and used by all ESXi hosts in a vSphere datacenter for example a disk or OVF image repository.
  • No errors detected in ONTAP event logs
  • Some ESXi use Atomic test and set ( ATS) and some ESXI have ATS disabled, only using SCSI reservation 

Example:

/var/run/log/vobd Abandoned event (esx.problem.vmfs.heartbeat.corruptondisk) after 6 failures.

/var/run/log/hostd info hostd[2184843] [Originator@6876 sub=Vimsvc.ha-eventmgr] Event 159405 : At least one corrupt on-disk heartbeat region was detected on volume abc_(NetApp). Other regions of the volume might be damaged too.
/var/run/log/hostd.0:-->    eventTypeId = "esx.problem.vmfs.heartbeat.corruptondisk"

Failed to send event (esx.problem.vmfs.heartbeat.corruptondisk); 2 failures so far.
/var/run/log/vobd  [vmfsCorrelator] 16326186567549us: [esx.problem.vmfs.heartbeat.corruptondisk] abc_NetApp
