環境

  • ONTAP
  • VMware ESXi

問題

  • 定期的なデータストア切断
  • データストアが破損する可能性があります。
  • 一般に、データストアは、ディスクやOVFイメージリポジトリなど、vSphereデータセンター内のすべてのESXiホストで共有および使用されます。
  • ONTAP イベントログでエラーは検出されませんでした
  • のESXiではAtomic Test and Set(ATS)使用ます 。一部のESXiでは、SCSI予約のみを使用してATSが無効になっています 

例:

/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
/var/run/log/vobd  An event (esx.problem.vmfs.heartbeat.corruptondisk) could not be sent immediately to hostd; queueing for retry.
