DELL(linux 系统里系统掉盘)(阵列Foreign)命令行里重做阵列

故障现象 (阵列Foreign 系统下重做阵列)

例:四合一机器(DELL_XENCOMPA09) 有四个硬盘

如图 少认到一个

df  -h 

fdisk -l 2>/dev/null | grep 'Disk /dev/'  -c

 

/opt/MegaRAID/MegaCli/MegaCli64   -LdInfo -Lall –aALL  可以确认认到几个盘

 

查看1

cat /proc/scsi/scsi

 

dmesg |grep -i raid

 

1.查看RAID卡的设备号

/opt/MegaRAID/MegaCli/MegaCli64  -PDList -aAll |grep "Device ID"

 

 2.查看Slot ID,有没有错序的情况

/opt/MegaRAID/MegaCli/MegaCli64  -PDList -aAll |grep "Slot"

 

3.查看Foreign信息

/opt/MegaRAID/MegaCli/MegaCli64  -PDList -aAll |grep "Foreign State"

 

4.清除Foreign信息

/opt/MegaRAID/MegaCli/MegaCli64 -CfgForeign -Clear -a0

5.再查看

/opt/MegaRAID/MegaCli/MegaCli64  -PDList -aAll |grep "Foreign State"

 

6重新做RAID,在Slot2做RAID0

 

7确认认到4个

fdisk -l 2>/dev/null | grep 'Disk /dev/'  -c

fdisk -l 2>/dev/null | grep 'Disk /dev/' 

 

/opt/MegaRAID/MegaCli/MegaCli64   -LdInfo -Lall –aALL  可以确认认到几个盘

有享不了的福 没有受不了的苦
