问题描述

MCC-IP 中的两个集群都会触发自动支持警报，指示：

- HA组通知(磁盘冗余失败)错误
- HA组通知(SyncMirror丛失败)警报
- HA 组通知（文件系统磁盘无响应）错误
- HA 组通知（健康监视器进程 schm：RaidDegradedMirrorAggrAlert[4c95d23d-1cad-49e3-8b37-0531b7b4a6e6]）警报
在 EMS 日志中观察到针对同一磁盘架的多个错误消息：

在包含受影响磁盘的 MCC 架的所有四个节点中，系统存储配置从四路径转换为混合路径或多路径
在 SYSCONFIG-A 中不可见，
MCC 的两侧都报告丢失的磁盘：
