Esxi 使用 RDM (Raw Device Mapping) 功能直接将磁盘分配给虚拟机，直通
如果你只想直通单个硬盘，而不是整个 SATA 控制器，也可以使用 RDM (Raw Device Mapping) 功能直接将磁盘分配给虚拟机。
或者是你的控制器不支持直通，也可以用这种方法将所有的硬盘直接分配给虚拟机使用。
1、创建一个专门用来存储 RDM 映射文件的目录
mkdir /vmfs/volumes/datastore1/passthru_disks
2、查看本机识别到的磁盘，t10 开头或者是 naa开头（这里把分区也列出来了，结尾是冒号加数字的就是分区，此处只看磁盘不看分区）

3、创建 RDM 映射文件（因为做的盘比较多，特意在RDM映射文件的名字中标注了盘的品牌型号和SN，方便后面维护和使用）
vmkfstools -z /vmfs/devices/disks/t10.ATA_____ST2000DM0012D1CH164__________________________________Z1E2PVS2 /vmfs/volumes/datastore1/passthru_disks/ST2000DM_Z1E2PVS2.vmdk vmkfstools -z /vmfs/devices/disks/t10.ATA_____TOSHIBA_DT01ACA100_________________________________97BD6G2MS /vmfs/volumes/datastore1/passthru_disks/TOSHIBA_97BD6G2MS.vmdk vmkfstools -z /vmfs/devices/disks/t10.ATA_____TOSHIBA_DT01ACA100_________________________________Y68G9BHNS /vmfs/volumes/datastore1/passthru_disks/TOSHIBA_Y68G9BHNS.vmdk vmkfstools -z /vmfs/devices/disks/t10.ATA_____TOSHIBA_DT01ACA100_________________________________Y68GBZXNS /vmfs/volumes/datastore1/passthru_disks/TOSHIBA_Y68GBZXNS.vmdk vmkfstools -z /vmfs/devices/disks/t10.ATA_____WDC_WD5000AAKX2D75U6AA0_______________________WD2DWCC2E5EKA3KR /vmfs/volumes/datastore1/passthru_disks/WDC_WD5000_EKA3KR.vmdk
4、在命令行查看创建好的 RDM 映射文件，一长一短两个文件，在使用的时候我们只使用短的文件名，but长文件的也不要删除哦。
[root@localhost:~] ls -l /vmfs/volumes/datastore1/passthru_disks total 0 -rw------- 1 root root 2000398934016 Dec 23 03:48 ST2000DM_Z1E2PVS2-rdmp.vmdk -rw------- 1 root root 487 Dec 23 03:48 ST2000DM_Z1E2PVS2.vmdk -rw------- 1 root root 1000204886016 Dec 23 03:49 TOSHIBA_97BD6G2MS-rdmp.vmdk -rw------- 1 root root 487 Dec 23 03:49 TOSHIBA_97BD6G2MS.vmdk -rw------- 1 root root 1000204886016 Dec 23 03:49 TOSHIBA_Y68G9BHNS-rdmp.vmdk -rw------- 1 root root 487 Dec 23 03:49 TOSHIBA_Y68G9BHNS.vmdk -rw------- 1 root root 1000204886016 Dec 23 03:49 TOSHIBA_Y68GBZXNS-rdmp.vmdk -rw------- 1 root root 487 Dec 23 03:49 TOSHIBA_Y68GBZXNS.vmdk -rw------- 1 root root 500107862016 Dec 23 03:49 WDC_WD5000_EKA3KR-rdmp.vmdk -rw------- 1 root root 485 Dec 23 03:49 WDC_WD5000_EKA3KR.vmdk
补充：在查询磁盘信息的时候，还可以使用命令 esxcli storage core device list
