问题描述

在禁用故障转移之前观察到 FCVI 端口断开：

Mon Jan 22 20:36:54 +0100 [CL01-01: ispfcvi2500_main3: fcvi.qlgc.received.disconnect:notice]: FC-VI adapter: Disconnect request received on port 5c. QP name = WAFL, QP index = 3, Remote node's system id = 537407299.

Mon Jan 22 20:36:54 +0100 [CL01-01: fcvi_cm: pfo.failover.start.error:debug]: params: {'port': '2', 'client': 'WAFL', 'partner': 'DR Primary Partner', 'trigger': 'IPFO_TRIG_PATH_DOWN', 'reason': 'Failover not enabled'}

接管已禁用消息已生成，几秒钟后会自动启用：

Mon Jan 22 20:36:56 +0100 [CL0101-01: cf_main: cf.fsm.takeoverOfPartnerDisabled:error]: Failover monitor: takeover of CL01-02 disabled (unsynchronized log).

Mon Jan 22 20:37:50 +0100 [CL0101-01: cf_main: cf.fsm.takeoverByPartnerDisabled:error]: Failover monitor: takeover of CL0101-01 by CL0101-02 disabled (unsynchronized log)

Mon Jan 22 20:38:20 +0100 [CL01-01: cf_main: cf.fsm.takeoverByPartnerEnabled:notice]: Failover monitor: takeover of ASH06NETAPPCL2-02 by ASH06NETAPPCL2-01 enabled

Mon Jul 22 20:39:20 +0100 [CL01-01: cf_main: cf.fsm.takeoverOfPartnerEnabled:notice]: Failover monitor: takeover of CL01-01 enabled

此外，还收到了以下 ems 警报：

Mon Jan 22 20:37:00 +0100 [CL01-01: monitor: monitor.globalStatus.critical:EMERGENCY]: Controller failover of CL01-02 is not possible: unsynchronized log.

Mon Jan 22 20:36:54 +0100 [CL01-01: fcvi_cm: nvmm.mirror.aborting:debug]: mirror of sysid 2, partner_type DR PARTNER and mirror state NVMM_MIRROR_ONLINE is aborted because of reason NVMM_ERR_LINK_DOWN.

交换机日志显示 RX 值较低：
