【Linux相關】VMware Esxi配置磁盤直通裸映射虛擬機

一、前言

基於VMware Exsi環境，考慮到特殊業務需求，需要直接將磁盤數據提供給虛擬機使用。
本文主要介紹，如何配置磁盤直通，將磁盤裸映射提供給虛擬機使用。

二、配置過程

1、通過VMware vSphere Client查看新增磁盤名稱，對比Exsi后台/vmfs/devices/disks/確定新增磁盤對應ID為naa.61866da0692804002855fa603ff25fd9、naa.61866da0692804002857277b3277bf87、naa.61866da069280400285727ff3a59e706、naa.61866da0692804002857290f4a8b4bfc

[root@localhost:~] ls /vmfs/devices/disks/

2、通過vmkfstools -z將新增磁盤映射到數據存儲指定虛擬磁盤文件中

[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為數據存儲路徑

[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、編輯虛擬機，添加虛擬磁盤文件到虛擬機上，之后重啟虛擬機即可看到映射磁盤
