問題

  • ESXiのvmkernel.logを確認すると、マウントされたすべてのLUNでほぼ一定のパス評価が発生していることを示すイベントが表示されます。

  • vobd ログには 、ホスト側で「Path redundancy to storage device」アラートが表示され ます。

Path redundancy to storage device naa.600a0980xxxxxxxxxxxxxxxxxxx degraded. Path vmhba4:C0:T181:L26 is down. Affected datastores: xxx.

Path redundancy to storage device naa.600a0980xxxxxxxxxxxxxxxxxxx degraded. Path vmhba4:C0:T181:L24 is down. Affected datastores: xxx.

  • これらのイベントは頻繁に発生し、send keyまたはmaintenance key SCSIコマンドの失敗とともに表示されます。

  • 失敗したSCSIコマンドのランタイムIDを確認します。 

vmhba64:C4:T0:L302

vmhba64:C3:T1:L302

  • この例では、LUN ID 302の場合、ESXiがSCSIコマンドを問題しようとしているターゲットはT0およびT1です。  LUNで実際に使用されているパスを確認すると、ターゲットIDが 異なることがわかります(T4)。
