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 WWN WWN: 500051610003776C WWN: 5000516100037BFC WWN: 5000516100038090 WWN: 50005161000284F4 WWN: 5000516100037C0C WWN: 5000516100037C5C WWN: 50005161000310C8 WWN: 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-3 Size : 7.275 TB State : Optimal Strip Size : 64 KB Number Of Drives : 6 Span Depth : 1 Default Cache Policy: WriteBack,ReadAhead,Direct,No Write Cache if Bad BBU Current Cache Policy: WriteBack,No Write Cache if Bad BBU Access Policy : Read/Write Disk Cache Policy : Disabled Ongoing Progresses: Check Consistency : Completed 17%,Taken 89 min.

来自lshw：
