  • 外付けシェルフの1台のPSUの電源が初めてオフになった場合、次のEMSイベントが両方のノードで発生することが予想されます。

  • 同じPSUの電源が6時間以内にオフになり ses.status.psWarning 、電源 ses.status.psError が遮断される場合は、次の手順を実行します。

Thu Aug 18 13:43:26 +0900 [Nodename: dsa_worker2: callhome.shlf.power.intr:error]: Call home for SHELF POWER INTERRUPTED
Thu Aug 18 13:43:35 +0900 [Nodename: statd: monitor.shelf.fault:alert]: Critical fault reported on disk storage shelf attached to channel 0a. Check fans, power supplies, disks, and temperature sensors.
Thu Aug 18 13:43:35 +0900 [Nodename: statd: callhome.shlf.fault:error]: Call home for SHELF_FAULT

  • これは外部シェルフに対する想定される動作であり、同じアラートリソースからの同じ警告メッセージは6時間以内に禁止されます。

追加情報

  • PSUのステータスは次の方法で確認できます。system node run -node * -command environment status
  • 内蔵シェルフ(シャーシ)に搭載されているPSUで障害が発生すると、この2つのEMSイベントが停止することはありません。
