问题描述

客户发现数据中断已持续数秒。示例：
- NFS导出已断开连接
- 无法访问CIFS共享
- 缺少VM
报告硬件磁盘故障。示例：

[node_name: config_thread: raid.config.filesystem.disk.not.responding:notice]: File system Disk /aggr_name/plex0/rg0/0a.0.1 Shelf 0 Bay 1 [...] is not responding.

[node_name: monitor: monitor.globalStatus.nonCritical:error]: Disk on adapter FPF1939S03T:9, shelf 1, bay 5, not responding.

数据和/或根聚合中报告了长CP的ONTAP事件错误。示例：

[node_name: wafl_exempt13: wafl.cp.toolong:error]: Aggregate aggr0 experienced a long CP. [node_name: wafl_exempt16: wafl.cp.toolong:error]: Aggregate aggr_name experienced a long CP.

向磁盘转储数据时、sktraces AutoSupport部分报告的一致点(CP)阶段2过长。示例：
