Detailed steps for deleting disk partitions under ESXi

If you add a disk that has been installed with an operating system (such as a disk that has been installed with a Windows system) to the vSphere Client, you cannot directly add a drive, you need to log on to the ESXi console through SSH.

After the disk is deleted, add a new disk to the vSphere Client.

Appendix esxcfg-scsidevs usage:

Single line, with limited information.
-U | -- uids List all Device Unique Identifiers with their primary name.
-D | -- device Used to filter the -- list, -- compact-list
And uids commands to limit output to
Specific device.
-M | -- vmfs Print mappings for VMFS volumes to their
Service Console partitions and vmhba names.

Usage of the partedUtil tool:
 
~ # PartedUtil-h
Usage:
Get Partitions: get <diskName>
Set Partitions: set <diskName> ["partNum startSector endSector type attr"] *
Delete Partition: delete <diskName> <partNum>
Resize Partition: resize <diskName> <partNum> <start> <end>
Get Partitions: getptbl <diskName>
Set Partitions: setptbl <diskName> <label> ["partNum startSector endSector type/guid attr"] *
Fix Partition Table: fix <diskName>
Create New Label (all existing data will be lost): mklabel <diskName> <label>
Show commonly used partition type guids: showGuids
Get usable first and last sectors: getUsableSectors <diskName>
Fix GPT Table interactively: fixGpt <diskName>
