  • IOM Aを取り付け直した後、sysconfig -a出力にIOM AのFW情報が表示されない。

Example: 
::> system node run -node <node_name> -command sysconfig -a
Shelf 10: DS224-12  Firmware rev. IOM12 A: 0300  IOM12 B: 0300
Shelf 11: DS224-12  Firmware rev. IOM12 A: ---- IOM12 B: 0300

 

  • シェルフのIOM A/シャーシ/SASケーブル/PSUを交換しても問題は解決しません。
  • シャーシの交換後、ENVIRONMENTログに表示されたケーブル接続と実際の接続に不整合がありました。 

Example: IOM Bは元の場所に設置されたままですが、ログにはIOM Aのスロットに挿入されていることが示されています。
シャーシ交換前

  • さらに、IOM AのLEDは消灯し、IOM BのLEDは点灯していますが、IOM Bのファームウェア情報が sysconfig-a ログに表示されなくなります。
  • 2台のIOMを別のシェルフにスワップすると、問題が再現されます。
