環境

  • AFF/FASシステム
  • Brocadeスイッチ

問題

  • FCリンクがターゲットポートで稼働していません。
  • sysconfig -a 出力は次のように表示されます(黄色で強調表示)。

CLIコマンド- system node run -node <node name> -command sysconfig -a

例:

slot 5: Fibre Channel Target Host Adapter 5b
         (Emulex LPe32000 (LPe32004) rev. 12, <LINK DISCONNECTED>)
         Board Name:     111-03648
         Serial Number:    FP01142277
         Firmware rev:    12.2.390.0
         Host Port Addr:   000000
         FC Nodename:     50:0a:09:80:80:23:6f:90 (500a098080236f90)
         FC Portname:     50:0a:09:82:80:23:6f:90 (500a098280236f90)
         Connection:     No link
         Switch Port:    Unknown
      SFP Vendor Name:   AVAGO
      SFP Vendor P/N:   AFBR-57G5MZ-ELX
      SFP Vendor Rev:   
      SFP Serial No.:   AD2003G02U1
      SFP Connector:    LC
      SFP Capabilities:  8, 16, 32 Gbit/Sec

Thu Mar 04 16:41:22 +0000 [XXXXXXXX_01: fct_tpd_work_thread_0: scsitarget.hwpfct.linkUp:notice]: Link up on Fibre Channel target adapter 5b.

  • 計画されているケーブル配線図に基づいて、の出力 portshow は、接続されているデバイスのWWPNが sysconfig -a 、出力に記載されているWWPNと異なることを示します。

例:

sysconfig -aの出力:

slot 5: Fibre Channel Target Host Adapter 5b
         (Emulex LPe32000 (LPe32004) rev. 12, <LINK DISCONNECTED>)
         Board Name:     111-03648

         FC Portname:    50:0a:09:82:80:23:6f:90 (500a098280236f90)
         Connection:     No link
         Switch Port:     Unknown
      SFP Vendor Name:   AVAGO
