環境

  • MetroCluster FC
  • ATTO 7600N ファイバブリッジ
  • ONTAP 9

問題

  • EMS レポートでは"fci.device.timeout"、と報告されます。

例:

Wed Jun 02 09:48:43 +0900 [node: slifc_timeout_3: fci.device.quiesce:debug]: Adapter 1d encountered a command timeout on Disk device PROD_FAB_1_SW3_D7:10.126 (0x0e070a00) LUN 10 cdb 0x28:4d2a22f8:0020 retry: 0 Quiescing the device.

Wed Jun 02 09:48:44 +0900 [node: slifc_timeout_3: fci.device.timeout:debug]: HBA 1d encountered a device timeout on Disk device PROD_FAB_1_SW3_D7:10.126 (0x0e070a00) LUN 10 cdb 0x28:4d2a22f8:0020 retry: 0

  • CRC エラーは、スイッチ PROD_FAB_1_SW3_D7 : 10 に接続された FibreBridge ポートで確認されます。

例:

1 )get FCPortErrors allATTO シリアルコンソールからを実行します

get FCPortErrors all
; Fibre Channel Error Counts
; Port | Link Failures | Sync Loss | Signal Loss | Invalid Tx | Invalid CRC
;==========================================================================
  1         717   56806347        0       22      1888   <<<<<CRC errors on FC1
  2          2      658        0      172        0

 

2) ASUP で「ストレージブリッジ」を調べます。
