一、前言

基于VMware ESXi环境，考虑到特殊业务需求，需要直接将磁盘数据提供给虚拟机使用。
本文主要介绍，如何配置磁盘直通，将磁盘裸映射提供给虚拟机使用。

二、配置过程

1、通过VMware vSphere Client查看新增磁盘名称，对比ESXi后台/vmfs/devices/disks/确定新增磁盘对应ID为naa.61866da0692804002855fa603ff25fd9、naa.61866da0692804002857277b3277bf87、naa.61866da069280400285727ff3a59e706、naa.61866da0692804002857290f4a8b4bfc

[root@localhost:~] ls /vmfs/devices/disks/
naa.5000c500a323807b                                        naa.50014ee0aeb167e9:8                                      vml.020000000050014ee0aeb167e9574443205744:1

2、通过vmkfstools -z将新增磁盘映射到数据存储指定虚拟磁盘文件中

[root@localhost:~] vmkfstools -z /vmfs/devices/disks/naa.61866da0692804002855fa603ff25fd9 /vmfs/volumes/datastore/naa.61866da0692804002855fa603ff25fd9.vmdk 

[root@localhost:~] vmkfstools -z /vmfs/devices/disks/naa.61866da0692804002857277b3277bf87 /vmfs/volumes/datastore/naa.61866da0692804002857277b3277bf87.vmdk

[root@localhost:~] vmkfstools -z /vmfs/devices/disks/naa.61866da069280400285727ff3a59e706 /vmfs/volumes/datastore/naa.61866da069280400285727ff3a59e706.vmdk

[root@localhost:~] vmkfstools -z /vmfs/devices/disks/naa.61866da0692804002857290f4a8b4bfc /vmfs/volumes/datastore/naa.61866da0692804002857290f4a8b4bfc.vmdk

注：/vmfs/volumes/datastore/中datastore为数据存储路径

[root@localhost:~] ls /vmfs/volumes/datastore/
CentOS-6.5-x86_64-bin-DVD1.iso                  naa.61866da0692804002857277b3277bf87-rdmp.vmdk  naa.61866da069280400285727ff3a59e706.vmdk       ubuntu-16.04.6-server-arm64.iso
naa.61866da0692804002855fa603ff25fd9-rdmp.vmdk  naa.61866da0692804002857277b3277bf87.vmdk       naa.61866da0692804002857290f4a8b4bfc-rdmp.vmdk  ubuntu-20.04.2.0-desktop-amd64.iso

3、编辑虚拟机，添加虚拟磁盘文件到虚拟机上，之后重启虚拟机即可看到映射磁盘
