Answer

During network cable disconnection tests, ASUP is not generated for certain NIC disconnections due to the default settings on ONTAP.
 
  • Behavior observed:
  1. Service(Data) NIC Cable Disconnection  - No ASUP message is generated.
EMS log:
[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 - No ASUP message is generated.
EMS log:
[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 message "HA INTERCONNECT DOWN" is generated.
EMS log:
[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 message "DISK REDUNDANCY FAILED" is generated.
EMS log:
[node: intr: netif.linkDown:info]: Ethernet e4a-30: Link down, check cable.
[node: intr: nvmeof.timeout:notice]: Timeout on subnqn nqn.2014-08.org.nvmexpress.discovery, controller ID 9, qpair ID 0, sequence number 3704.
[node: intr: nvmeof.timeout:notice]: Timeout on subnqn nqn.2014-08.org.nvmexpress:1b96:1b96:241163800956:X4032WCOFB15TNVE, controller ID 9, qpair ID 0, sequence number 2017.
[node: intr: nvmeof.timeout:notice]: Timeout on subnqn nqn.2014-08.org.nvmexpress:1b96:1b96:241025800131:X4032WCOFB15TNVE, controller ID 9, qpair ID 0, sequence number 2066.
[node: dsa_disc: callhome.dsk.redun.fault:error]: Call home for DISK REDUNDANCY FAILED.
 
  • Reason:
    • With disconnecting the HA-Interconnect NIC and Disk Shelf NIC reports the "hainterconnect.down" and "dsk.redun.fault" are defined to send ASUP as below:
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
 
ontap914::> system node autosupport trigger show -fields autosupport-message,to,noteto -node ontap914-01  -autosupport-message *dsk.redun*
node        autosupport-message to      noteto
----------- ------------------- ------- -------
ontap914-01 dsk.redun.fault     enabled enabled
  • But disconnecting the Service(Data) NIC and Cluster-Interconnect NIC reports netif.linkDown and vifmgr.portdown etc are not defined to send ASUP:

ontap914::> system node autosupport trigger show -fields autosupport-message,to,noteto -node ontap914-01  -autosupport-message *net*        

node        autosupport-message to      noteto
----------- ------------------- ------- -------
ontap914-01 clus.net.degraded   enabled enabled
ontap914-01 mcc.network.stats   disabled disabled
ontap914-01 netif.fatal.error   enabled enabled
ontap914-01 netif.init.failed   enabled enabled
ontap914-01 netif.uncorEccError enabled enabled
ontap914-01 netinet.dup.clustIP enabled enabled
6 entries were displayed.
