環境

  • NSM100
  • NSM100B
  • ONTAP 9

問題

  • マルチディスクパニック(MDP)による単一ノードの再起動:

[Node2: config_thread: cf.multidisk.fatalProblem:error]: Node encountered a multidisk error or other fatal error while waiting to be taken over.

  • ノードは正常に再起動し、その後ディスクの問題は発生しなかった。
  • EMSによると、ストレージポートが同時にダウンしている:

[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3a: Link down, check cable.
[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3a-30: Link down, check cable.
[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3b: Link down, check cable.
[Node2: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e3b-30: Link down, check cable.

  • EMSは、単一モジュールの再起動に関するメッセージを表示します:

[Node2: storlog_admin: sla.shelf.mod.reboot:notice]: Reboot event reported by module B in shelf: 0s.0.0, log: Wed Mar 18 02:08:50 2026 (   0+00:08:26.577); 02000233; U?; HAL; hal; 04; +++ Application version 0140 launching +++

  • 環境出力によると、再起動したノードには同じモジュールへのパスが2つ存在します:
