假设我知道我想要的驱动器在适配器 8、虚拟驱动器 0 上，有没有办法获取 Linux 设备名称（例如/dev/sdt）？我在 RHEL 6.2 上。
-pdlist为每个物理驱动器显示一个 WWN 值，但这并没有多大帮助。-ldinfo不打印 WWN 或任何其他标识值。
# ./MegaCli64 -pdlist -a8 | grep WWN
WWN: 500051610003776C
WWN: 5000516100037BFC
WWN: 5000516100038090

您应该能够将 的磁盘序列号-pdlist与 的输出进行比较lshw。
# MegaCLI -pdlist -a0 | grep "Inquiry Data:"
Inquiry Data: XXXXXXXXXXXXHitachi YYYYYYYY ZZZZZZ
...
然后搜索lshw序列号的输出。设备名称将出现在该logical name字段中。
我无法验证这一点，因为我的所有磁盘都在一个卷中。
将Target IdMegaCLI 中的 与设备的 scsi 总线目标进行比较。在lshw它是bus info。
# MegaCli -ldinfo -Lall -aall

我刚刚为 megaclisas-status 的分支添加了一些支持，以便将逻辑驱动器与 OS Native 设备相匹配。这是一个示例输出：

对于任何在这个问题上绊倒并使用storcli（的后继MegaCLI）的人，您可以使用以下命令将虚拟驱动器映射到操作系统看到的磁盘：
$ /opt/MegaRAID/storcli/storcli64 /c0/v0 show all | grep NAA
SCSI NAA Id = 6001676001750006201086de0bd7f605
$ ls -al /dev/disk/by-id/ | grep wwn-0x6001676001750006201086de0bd7f605
lrwxrwxrwx 1 root root 9 Jan 23 10:55 wwn-0x6001676001750006201086de0bd7f605 -> ../../sdk
测试storcli-1.21.06下载地址：https : //docs.broadcom.com/docs/1.21.06_StorCLI
而不是使用lshw，我认为您可以使用/dev/disk/by-path来获取 scsi 目标 id 和逻辑设备名称（sdX）之间的关系。
targetId=0;dev=`ls -l /dev/disk/by-path/ | grep -E "scsi-[0-9]:[0-9]:${targetId}:[0-9] " | awk '{print($11)}'`; echo ${dev##*\/}
deviceId=$1
ldPdInfo=`$MegaCommand -LdPdInfo -aALL | grep -E 'Virtual Drive|Device Id'`
if [ $ldPdInfo ]; then
targetId=`echo $ldPdInfo | awk '{a[NR]=$0} END {while (NR) print a[NR--]}' | awk "/Device Id: ${deviceId}$/,/Virtual Drive/" | grep -Eo 'Target Id: [0-9]' | grep -Eo '[0-9]'`
dev=`ls -l /dev/disk/by-path/ | grep -E "scsi-[0-9]:[0-9]:${targetId}:[0-9] " | awk '{print($11)}'`
else
wwn=`$MegaCommand -PdList -aALL | awk "/Device Id: ${deviceId}$/,/WWN/" | grep "WWN" | awk '{print($2)}'`
# wwn=`echo "obase=16;ibase=16; $wwn-1" | bc`
dev=`ls -l /dev/disk/by-id/ | grep -i -E "wwn-0x${wwn:0:-1}[0-9a-z] " | awk '{print($11)}'`
fi
devName=${dev##*\/}
echo $devName
