使用partedUtil格式化磁盘

here is your one line magical command that will wipe that disk clean:

#PartedUtil mklabel /dev/disks/<disk id> msdos

Below is an example of how it looked like in my environment.

#partedUtil mklabel /dev/disks/t10.ATA____WDC_WD5000AK52000UU340___________WD2DWCAYU6597660 msdos

Alright in case you have wondered how did I figured out my disk id, all I had to do to get that info is to run the following command just as demonstrated in the previous screenshot:

#ls /dev/disks

After wiping the LUN/Disk clean, now you should be able to use it to create your new VMFS datastore by adding it through the vSphere client(business as usual).
