Symptoms
创建分布式设备后,所连接设备的扩展区和分布式设备组件变为“严重故障”状态。

Cause
将镜像分支连接到现有设备后,连接设备范围进入严重故障状态。这可能是因为重建已初始化并且设备正在重建。
这可以在固件日志中检查:

1.检查重建的状态,以验证重建是否仍在设备上运行:
2.您需要等到重建完成才能执行此作,并在为 ETA 显示的分配时间后再次运行步骤 1 中的命令,以查看重建是否已完成:
3.然后,一旦看到重建已完成,请再次运行 show-use-hierarchy 命令以确保已清除严重故障状态:
VPlexcli:/>rebuild status

2.您需要等到重建完成才能执行此作,并在为 ETA 显示的分配时间后再次运行步骤 1 中的命令,以查看重建是否已完成:
VPlexcli:/> rebuild status

No active global rebuilds.
本地重建:
没有活动的本地重建。

3.然后,一旦看到重建已完成,请再次运行 show-use-hierarchy 命令以确保已清除严重故障状态:

4.如果在“rebuild status”显示重建已完成并且您运行“show-use-hierarchy”后,分布式设备组件和设备仍显示为“critical-failure”状态,则需要验证存储卷的运行状况。如果存储卷处于“严重故障”状态,请参阅知识库文章:
499075“存储卷处于严重故障状态”,
495253“由于 scsi 检查条件,存储卷处于严重故障状态”。
