适用于

  • MetroCluster IP
  • 双端口 40/100G 以太网 T62100-CR 网卡 P/N X1146A
  • 受影响端口连接到共享的 MetroCluster/集群网络交换机

问题

  • 多个 AutoSupport HA Group Notification (HA INTERCONNECT DOWN) ALERT
  • SYSCONFIG -A AutoSupport 部分或 ONTAP 命令行界面 (CLI) 输出  ::> system node run -node node_name -command sysconfig -a显示其中一个 T6 卡端口"关闭"。示例
slot 1: Dual 40/100G Ethernet T62100-CR
e1a MAC Address:   00:00:00:00:00(auto-100g_sr4-fd-up)
   QSFP Vendor:     FINISAR CORP   
   QSFP Part Number:   FTLC9558REPM   
   QSFP Serial Number:  A12b3CD     
e1b MAC Address:   00:10:00:00:00(auto-unknown-fd-down)
   QSFP Vendor:     
   QSFP Part Number:   
   QSFP Serial Number:  
  • AutoSupport IFSTAT-A 部分或 ONTAP CLI 输出 "::> system node run -node node_name -command ifstat e1b"    可能会在该端口上显示递增的 CRC 错误或 "Media state: no carrier" 具有大量的 "Up to downs"
    • ifconfig -vvv AutoSupport 部分或 ONTAP CLI 输出   ::> system node run -node node_name -command ifconfig -vvv 检测到收发器,但状态为 "no carrier"。
  • 处于脱机状态的  ::> metrocluster interconnect show -partner-type HA的 ONTAP CLI 输出 
    • 连接的交换机端口也可能被禁用 
  • 此方案的 ONTAP 事件示例:

... [node_name: intr: netif.linkDown:info]: Ethernet e1b: Link down, check cable.
... [node_name: nchmd: hm.alert.raised:alert]: Alert Id = MccIp_PortOfflineAlert , Alerting Resource = node_name_t6nex1_e1b raised by monitor node-connect
... [node_name: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process nchm: MccIp_PortOfflineAlert[node_name_t6nex1_e1b].

  • 在某些情况下,可能会出现抖动 port 情况。示例

... [node_name: intr: netif.linkUp:info]: Ethernet e1b: Link up.
... [node_name: intr: netif.linkDown:info]: Ethernet e1b: Link down, check cable.
... [node_name: intr: netif.linkUp:info]: Ethernet e1b: Link up.
... [node_name: intr: netif.linkDown:info]: Ethernet e1b: Link down, check cable.
... [node_name: intr: netif.linkUp:info]: Ethernet e1b: Link up.
... [node_name: nchmd: hm.alert.cleared:notice]: Alert Id = MccIp_PortOfflineAlert , Alerting Resource = node_name_t6nex1_e1b cleared by monitor node-connect
