问题描述

使用正常运行的HA配对节点的自动支持端口重新启动AWS CVO节点： HA组通知(缺少多个磁盘)错误。从运行正常的节点的EMS日志中可以看出、该节点已无法访问连接到故障节点的镜像Pool1磁盘：

Mon Jun 03 16:23:02 +0000 [CVO-01: monitor: monitor.globalStatus.critical:EMERGENCY]: This node has taken over CVO-02. One or more mirrored aggregates are degraded.

Mon Jun 03 16:22:35 +0000 [CVO-01: dmgr_thread: raid.disk.missing:info]: Disk /aggr1/plex1/rg0/0d.10 S/N [00000000V9NeubcHXfRG] UID [00000000V9NeubcHXfRG] is missing from the system Mon Jun 03 16:22:35 +0000 [CVO-01: config_thread: raid.config.filesystem.disk.missing:info]: File system Disk /aggr1/plex1/rg0/0d.10 S/N [00000000V9NeubcHXfRG] UID [00000000V9NeubcHXfRG] is missing.

(对于受影响节点CVO -02拥有的所有磁盘、均会显示此信息)

在此事件发生后不久、通常还会显示AutoSupport：HA组通知(SyncMirror丛失败)警报、这是缺失磁盘的剩余现象
重新启动节点后、它能够重新建立与提供的AWS磁盘的连接、并且已成功完成了恢复
