1、找到nvme硬盘设备

[root@localhost:~] esxcli nvme device list
HBA Name  Status  Signature
--------  ------  ---------
vmhba2    Online  nvmeMgmt-nvmhba0

2、查看nvme硬盘的具体信息，防止选错硬盘

[root@localhost:~] esxcli nvme device get -A vmhba2  | egrep -A1 "Model|Serial"
   Serial Number: VMware NVME_0000
   Model Number: VMware Virtual NVMe Disk
   Firmware Revision: 1.3

3、查看硬盘支持的LBA格式，以及当前使用的LBA格式

[root@localhost:~] esxcli nvme device namespace get -A vmhba2 -n 1 | grep -A 4 'LBA Format'
   Number of LBA Formats: 0
   LBA Format: 0
   Extended Metadata: false
   Metadata as Seperate Buffer Support: false
   Metadata as Extended Buffer Support: false
   PI Type 1 Support: false
--
   LBA Format Support:
         Format ID: 0
         LBAData Size: 4096
         Metadata Size: 0
         Relative Performance: Best performance
--
   LBA Format Support:
         Format ID: 1
         LBAData Size: 512
         Metadata Size: 0
         Relative Performance: Best performance

4、切换LBA格式到512

[root@localhost:~] esxcli nvme device namespace format -A vmhba2 -f 1 -n 1 -m 0 -p 0 -l 0 -s 0
Format successfully!

5、再次查看当前使用的LBA格式

[root@localhost:~] esxcli nvme device namespace get -A vmhba2 -n 1 | grep -A 4 'LBA Format'
   Number of LBA Formats: 0
   LBA Format: 1
   Extended Metadata: false
   Metadata as Seperate Buffer Support: false
   Metadata as Extended Buffer Support: false
   PI Type 1 Support: false
--
   LBA Format Support:
         Format ID: 0
         LBAData Size: 4096
         Metadata Size: 0
         Relative Performance: Best performance
--
   LBA Format Support:
         Format ID: 1
         LBAData Size: 512
         Metadata Size: 0
         Relative Performance: Best performance

6、LBA格式切换的参数说明

[root@localhost:~] esxcli nvme device namespace format
