環境

  • ONTAP 9
  • ファブリックMetroCluster
  • FAS / AFFシステム

問題

  • FCアダプタはファブリックMetroCluster構成でオフラインです。

cluster1::> system node run -node node1 -command sysconfig -a

slot 1: FC Host Adapter 1a (Emulex XE501 rev. 1, <OFFLINE (hard)>)
         Board name:     111-03648
         Serial Number:    FP12345678
         Firmware rev:    11.4.277.0
         Host Port Id:    N/A
         FC Node Name:    2:000:00109b:ea9206
         FC Port Name:    1:000:00109b:ea9206
         Link Data Rate:   N/A

  • イベントログでは次のアラートが報告されます。

[Node-01: nchmd: hm.alert.raised:alert]: Alert Id = StorageFCAdapterFault_Alert , Alerting Resource = 10000010XXXX206 raised by monitor node-connect

  • MetroClusterノードのヘルスがデグレード状態になる原因は次のとおりです。

cluster1::> system health subsystem show

  • ノード構成が「クアッドパス」構成ではなく「マルチパス」構成に変更されることがあります。

  • スイッチのログから、該当するFCポートに接続されているスイッチポートが No_Sync No_Light:

MCC-sw2:admin>switchshow
switchName: MCC-sw2
switchType:  181.0
switchState: Online
switchMode:  Native

Index Port Address  Media Speed   State     Proto
==================================================
  8   8   070800   id   32G   No_Sync   FC

  • ノードのFCポートとスイッチポートの間のケーブルを抜き差しします。
  • パスが8(クラスタあたり)/パスが4(ノードあたり)未満である1つ以上のディスク:
    ::> storage show disk -fields path-count -path-count !8 -type !LUN
