由于网络拥塞导致接管已禁用警报
适用场景
- ONTAP 9
- MetroCluster IP
- AFF A250 (软件iWARP)
问题描述
- MetroCluster IP配置中报告的已禁用接管警报：
[Node_A1: cf_main: cf.fsm.takeoverOfPartnerDisabled:error]: Failover monitor: takeover of Node_A2 disabled (unsynchronized log).
- 接管功能在几秒钟内自动恢复：
[NodeA1: cf_main: cf.fsm.takeoverOfPartnerEnabled:notice]: Failover monitor: takeover of Node_A2 enabled
- ONTAP报告 网络拥塞事件：
[Node_A1: mccip_mirror_congestion_mgr_p: mcc.network.congestion:notice]: Network congestion detected. Action taken: Increased ic_timeout to 1200 msec.
- 节点的ifstat输出可能会在e0c/e0d端口上报告高TX错误。
- SW_iWARP线程导致主机利用率较高
