1.目前的环境:
刀片服务器的型号为:IBM BladeCenter S,里面配置的刀片为6个HS22。后面的磁盘SM1,SM2映射关系见下面详细说明。
2.遇到的问题如下:
之前运行正常,前几天机房断电重启之后,发现6个HS22刀片都识别不SM1和SM2的硬盘,目前 BladeCenter Mangement管理界面可以远程登录,登陆上去无任何错误报警。这些硬盘里面有数据,希望能有熟悉这个刀片型号的专家帮忙解决这个问题,挂载上硬盘,谢谢。
(1)其中一台HS22刀片上面显示如下,其他刀片一样都识别不了SM的硬盘:

(2)SM1和SM2的映射关系如下所示:
刀片存储映射关系:
SM1
1 2 3 300G 300G 300G
4 5 6 300G 1T 1T
1,2做RAID1; 3,4做RAID1; 5,6做RAID1
SM2

4 5 6 1T 1T 1T
1,2做RAID1; 3,4做RAID1; 5,6做RAID1
