FC-VI适配器：由于接收帧错误、丢弃了接收到的帧

适用场景

• 光纤连接 MetroCluster
• ONTAP 9

问题描述

• EMS报告Discarded a received frame because of a receive frame error 。

[Node-A: ispfcvi2500_main4: fcvi.qlgc.FrameDiscardErr:error]: FC-VI adapter: Discarded a received frame because of a receive frame error. Port 0f, QP name = WAFL, QP index = 4, exchange ID 0x1a5, address offset 0xa000, remote node's system id = xxxxxxx.

• 由于接收帧错误、可能会重置FFC-VI端口：

[Node-A: ispfcvi2500_main2: fcvi.qlgc.receive.error:error]: FC-VI adapter: Received bad frame on port 0f. Mailbox-1 = 520, Mailbox-2 = 324. Resetting the port.
[Node-A: ispfcvi2500_port2: fcvi.update.link.state:notice]: FC-VI adapter: Physical link is down on port 0f.
[Node-A: fcvi_reset_proc: callhome.mcc.fcvi.reset:notice]: Call home for METROCLUSTER FCVI RESET
[Node-A: ispfcvi2500_port2: fcvi.update.link.state:notice]: FC-VI adapter: Physical link is up on port 0f.
