問題

  • E シリーズストレージアレイでファームウェアの更新を実行している間に、接続された ONTAP ファブリック MetroCluster が、 SCSI タイムアウトエラーが原因で複数のディスクで障害が発生したと報告しています。
 
例:
Fri Dec 04 20:09:18 EST [node1: config_thread: raid.config.filesystem.disk.not.responding:notice]: File system Disk /node1/plex0/rg0/switch1:12.126L119 Shelf - Bay - [NETAPP   INF-01-00        0842] S/N [xxxxxxxxxxxxxxxxxxxxxx] UID [xxxxxxxx:xxxxxxxx:xxxxxxxx:xxxxxxxx:00000000:00000000:00000000:00000000:00000000:00000000] is not responding.
  • このようなエラーが発生すると、 MetroCluster の両方のクラスタで複数の SyncMirror プレックスに障害が発生する可能性があります。

Aggregate aggrname (online, raid0, mirror degraded) (block checksums)
  Plex /aggrname/plex0 (offline, failed, inactive)
    RAID group /aggrname/plex0/rg0 (partial, block checksums)
