linux – MegaCli：获取逻辑驱动器的 devsd *设备名称

概述假设我知道我想要的驱动器是适配器8,虚拟驱动器0,有没有办法获取 Linux设备名称(例如/ dev / sdt)？我在RHEL 6.2上. -pdlist显示每个物理驱动器的WWN值,但这没有多大帮助. -ldinfo不打印WWN或任何其他标识值. # ./MegaCli64 -pdlist -a8 | grep WWNWWN: 500051610003776CWWN: 5000516100 假设我知道我想要的驱动器是适配器8,虚拟驱动器0,有没有办法获取 Linux设备名称(例如/ dev / sdt)？我在RHEL 6.2上.

-pdList显示每个物理驱动器的WWN值,但这没有多大帮助. -ldinfo不打印WWN或任何其他标识值.

# ./MegaCli64 -pdList -a8 | grep WWNWWN: 500051610003776CWWN: 5000516100037BFCWWN: 5000516100038090WWN: 50005161000284F4WWN: 5000516100037C0CWWN: 5000516100037C5CWWN: 50005161000310C8WWN: 5000516100037F4C# ls -1dt /dev/disk/by-ID/wwn*/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd142c12c84d/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd142c0973e6/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd132c002573/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd122bf6e2f6/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd122beda52a/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd112be46f10/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd112bdb3ffb/dev/disk/by-ID/wwn-0x600605b0043e52d01721fd102bd20f14# ./MegaCli64 -v                        MegaCli SAS RAID Management Tool  Ver 8.03.08 Mar 15,2012

解决方法 您应该能够将-pdList中的磁盘序列号与lshw的输出进行比较.

# MegaCli -pdList -a0 | grep "Inquiry Data:"Inquiry Data:       XXXXXXXXXXXXHitachi YYYYYYYY                 ZZZZZZ...

然后在lshw的输出中搜索序列号.设备名称将位于逻辑名称字段中.

我无法验证这一点,因为我的所有磁盘都在卷中.

识别逻辑驱动器

将MegaCli的Target ID与设备的scsi总线目标进行比较.在lshw中它是公共汽车信息.

# MegaCli -ldinfo -Lall -aall Adapter 0 -- Virtual Drive information:Virtual Drive: 0 (Target ID: 0)name                :RAID Level          : Primary-6,Secondary-0,RAID Level QualifIEr-3Size                : 7.275 TBState               : OptimalStrip Size          : 64 KBNumber Of Drives    : 6Span Depth          : 1Default Cache Policy: WriteBack,ReadAhead,Direct,No Write Cache if Bad BBUCurrent Cache Policy: WriteBack,No Write Cache if Bad BBUAccess Policy       : Read/Writedisk Cache Policy   : DisabledOngoing Progresses:  Check Consistency        : Completed 17%,Taken 89 min.Encryption Type     : NoneVirtual Drive: 1 (Target ID: 1)name                :RAID Level          : Primary-6,Taken 89 min.Encryption Type     : None

来自lshw：
