回答

ネットワークケーブルの切断テストでは、ONTAPのデフォルト設定が原因で、特定のNICの切断時にASUPが生成されません。
 
  • 観察された動作:
  1. Service(Data)NIC Cable Disconnection  - ASUPメッセージは生成されません。
EMSログ:
[node: intr: netif.linkDown:info]: Ethernet e2a: Link down, check cable.
[node: intr: net.ifgrp.lacp.link.inactive:error]: ifgrp a0a, port e2a has transitioned to an inactive state. The interface group is in a degraded state.
[node: vifmgr: vifmgr.portdown:notice]: A link down event was received on node node, port e2a.
  1. Cluster Interconnect NIC Cable Disconnection - ASUPメッセージは生成されません。
EMSログ:
[node: intr: netif.linkDown:info]: Ethernet e1a: Link down, check cable.
[node: vifmgr: vifmgr.portdown:notice]: A link down event was received on node node, port e1a.
[node: vifmgr: vifmgr.clus.linkdown:EMERGENCY]: The cluster port e1a on node node has gone down unexpectedly.
[node: vifmgr: vifmgr.lifmoved.linkdown:notice]: LIF node_clus2 (on virtual server 4294967293), IP address 169.254.254.83, is being moved to node node, port e0a.
[node: vifmgr: vifmgr.reach.noreach:notice]: Network port e1a on node node cannot reach its expected broadcast domain Cluster:Cluster. No other broadcast domains appear to be reachable from this port.
  1. HA-Interconnect NIC Cable Disconnection - ASUPメッセージ「HA interconnect down」が生成されます。
EMSログ:
[node: statd: ic.HAInterconnectDown:error]: HA interconnect: Interconnect down for 2 minutes: link0 down
[node: statd: callhome.hainterconnect.down:alert]: Call home for HA INTERCONNECT DOWN due to link0 down.
  1. Disk Shelf Connection NIC Cable Disconnection - ASUPメッセージ「disk redundancy failed」が生成されます。
EMSログ:
[node: intr: netif.linkDown:info]: Ethernet e4a-30: Link down, check cable.

  • 理由:
    • HAインターコネクトNICディスクシェルフNICを切断すると、 hainterconnect.down 次のようにASUP」とdsk.redun.faultが送信されるように定義されます。
ontap914::> system node autosupport trigger show -fields autosupport-message,to,noteto -node ontap914-01  -autosupport-message *hainterconnect.down*
node     autosupport-message to    noteto
----------- ------------------- ------- -------
ontap914-01 hainterconnect.down enabled enabled

  • ただし、 サービス(データ)NIC クラスタインターコネクトNICを切断する と、 netif.linkDown と vifmgr.portdown  などがASUPを送信するように定義されていません。
