linux查看硬盘阵列卡信息命令,查看服务器RAID卡信息的SHELL脚本及MegaCLI命令介绍...
目前维护的dDell服务器,大多使用的都是LSI的MegaRAID卡。
查看系统使用的什么RAID卡,可以使用以下命令:# dmesg |grep -i raid
# cat /proc/scsi/scsi
# lspci
MegaRAID卡,可以通过官方提供的工具MegaCli来进行检查和控制。
下面是自动检查服务器RAID信息的SHELL脚本:#!/bin/sh
Hostname=`/bin/hostname`
Hostip=`ifconfig eth0|grep 'inet addr'|sed 's/.*addr:\(.*\) Bcast.*/\1/'`
Battery=`/opt/MegaCli -AdpBbuCmd -GetBbuStatus -aALL|grep "Charger Status"|awk -F: '{print $1":"$2}'`
raid=`/opt/MegaCli -cfgdsply -aALL|grep "RAID Level"|tail -1|awk -F: '{print $1" :"$2}'`
Disknum=`/opt/MegaCli -cfgdsply -aALL|grep -c "Non Coerced Size"`
Onlinedisk=`/opt/MegaCli -cfgdsply -aALL | grep “Online” | wc -l | sed 's/ //'`
Faileddisk=`/opt/MegaCli -AdpAllInfo -aALL | grep "Failed Disks"|awk -F' ' '{print $4}'`
echo "===================== Host Information ====================="
echo "HostName : $Hostname"
echo -e "HostIp : $Hostip\n"
echo "===================== Raid Information ====================="
#echo "$Raidmode"
case "$raid"
in
"RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0") echo "Raid Level :Raid 1";;
"RAID Level : Primary-0, Secondary-0, RAID Level Qualifier-0") echo "Raid Level :Raid 0";;
"RAID Level : Primary-5, Secondary-0, RAID Level Qualifier-3") echo "Raid Level :Raid 5";;
"RAID Level : Primary-1, Secondary-3, RAID Level Qualifier-0") echo "Raid Level :Raid 10";;
esac
if [ -z "$Battery" ];then
echo "Battery :Null"
else
echo "$Battery"
fi
echo "Total Diak Number:$Disknum"
echo "Online Disk Number:$Onlinedisk"
echo "Failed Disk Number:$Faileddisk"
脚本运行结果:===================== Host Information =====================
HostName : vps.cszhi.com
HostIp : 199.15.166.*
===================== Raid Information =====================
Raid Level :Raid 5
Charger Status: Complete
Charger Status: Complete
Total Diak Number:9
Online Disk Number:0
Failed Disk Number:0

磁带状态的变化,从拔盘,到插盘的过程中:Device |Normal|Damage|Rebuild|Normal
Virtual Drive |Optimal|Degraded|Degraded|Optimal
Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online
磁盘各个状态说明:A physical disk drive property indicating the status of the drive. A physical disk drive can be in one of
the following states:
>Unconfigured Good
A disk accessible to the RAID controller but not configured as a part of a virtual disk or as a hotspare.
>Online
A physical disk can be accessed by the RAID controller and is part of the virtual disk.
>rebuild
A physical disk to which data is being written to restore full redundancy for a virtual disk.
>failed
A physical disk that was originally configured as Online but on which the firmware detects an unrecoverable error.
>Unconfigured bad
A physical disk on which the firmware detects an unrecoverable error; the physical disk was Unconfigured Good or the physical disk could not be initialized.
Disks with a status of "Unconfigured bad" cannot be used for RAID configurations.
>Missing
A physical disk that was Online, but which has been removed from its location.
>offline
The drive is offline or absent. No actions can be performed on the drive until it is back online.
>Global hotspare
The drive will be used to repair any array in the system that had a drive failure, if the failed drive is equal to, or smaller than the hot spare drive.
>Ready
The drive is online and operating correctly.
>Foreign
The drive is part of an array created on a different controller, or created within one enclosure and moved to another on the same controller. It can be used to create a new array after clearing configuration.
>None
A physical disk with the unsupported flag set. An Unconfigured Good or Offline physical disk that has completed the prepare for removal operation.
>copyback
A bad physical disk replaced by a good one, then hotspare will copyback data to the good one and change back to hotspare
