由于MCC交换机上的C3超时、FFC-VI适配器会丢弃帧

• ONTAP 9
• 光纤连接 MetroCluster
• Brocade后端MetroCluster交换机

• 为 光纤通道虚拟接口 (FCVI)重置生成的警报(电子邮件、Auto支持、SNMP陷阱等)：

HA Group Notification from s1node1 (Reset occured on FCVI port 0f) NOTICE

• 节点事件日志指示FCVI端口经常发生帧丢弃

[s1node1: ispfcvi2500_main1: fcvi.qlgc.received.disconnect:notice]: FC-VI adapter: Disconnect request received on port 0f. QP name = Control, QP index = 2, Remote node's system id = XXXXXXXXX.
[s1node2: ispfcvi2500_main1: fcvi.qlgc.received.disconnect:notice]: FC-VI adapter: Disconnect request received on port 0f. QP name = Control, QP index = 2, Remote node's system id = XXXXXXXXX.
[s2node1: ispfcvi2500_main1: fcvi.qlgc.received.disconnect:notice]: FC-VI adapter: Disconnect request received on port 0f. QP name = Control, QP index = 6, Remote node's system id = XXXXXXXXX.
[s2node2: ctrl_hb_port_fcvi_device_1: fcvi.qlgc.sent.disconnect:notice]: FC-VI adapter: Disconnect request sent on port 0f. QP name = Control, QP index = 2, Remote node's system id = XXXXXXXXX.

• Brocade后端MetroCluster交换机的supportshow输出指示：

1.多帧超时。

errdump -a     :

[AN-1014], 1309, FID 128, INFO, s1switch1, Frame timeout detected, tx port 0 rx port 4, sid 80400, did 80000, timestamp 2023-03-19 05:33:44.
[AN-1014], 1316, FID 128, INFO, s1switch1, Frame timeout detected, tx port 0 rx port 20, sid 60000, did 80000, timestamp 2023-03-19 05:33:44.

2.高链路故障
