背景

近日操作移动一台R620 外接MD1400的设备。系统关机、服务器、存储断电、移机、链接、加电、开机，一气呵成。

但是。。。。。

系统起来后，fdisk -l 没有发现MD1400的硬盘信息，/var/log/message 日志如下

没有找到原因，重启系统，慢慢等待，识别ok了。但是没有lvm逻辑分区卷，这可如何挂载。

vgdisplay \lvdisplay 反馈都是空

解决方式

一、vgscan

　以为是ok了，结果mount时提示

mount : special device /dev/VolGroup00/LogVol00 does not exist

　原因 lvdisplay中 LV status 不正确

  LV Status              NOT available

　执行挂载命令，挂载成功。数据访问正常。
