问题解答

由于ONTAP上的默认设置、在网络缆线断开测试期间、不会为某些NIC断开连接生成ASUP。

观察到的行为：

服务(数据) NIC电缆断开连接 -未生成ASUP消息。

EMS日志：

[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.

集群互连NIC电缆断开连接 -不生成ASUP消息。

EMS日志：

[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.

HA互连NIC电缆断开连接— 生成ASUP消息"HA互连已关闭"。

EMS日志：

[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.

磁盘架连接NIC电缆断开连接-生成ASUP消息"磁盘冗余失败"。

EMS日志：

[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: dsa_disc: callhome.dsk.redun.fault:error]: Call home for DISK REDUNDANCY FAILED.

原因:
- 断开HA互连NIC和磁盘架NIC的连接后、会报告"hainterconnect.down "和"dsk.redun.fault "被定义为发送ASUP、如下所示：

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

但是、断开 服务(数据) NIC 和集群互连NIC 的连接会报告 netif.linkDown 和 vifmgr.portdown 等未定义为发送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.

ontap914::> system node autosupport trigger show -fields autosupport-message,to,noteto -node ontap914-01 -autosupport-message *vifmgr* There are no entries matching your query.
