When creating a VMFS5 datastore on a disk that has existing partitions, the first action should be to delete those existing partitions manually. This step is crucial because VMFS datastores are designed to occupy an entire disk or LUN. If there are existing partitions, they can interfere with the creation of the new VMFS5 filesystem, as the storage device needs to be prepared specifically for VMFS usage.

Using the partedUtil command is the most straightforward way to handle this situation, as it allows for safe management of disk partitions within the ESXi environment. Removing the partitions ensures that the disk is clean and that any remnant data or structures from the previous filesystem do not conflict with the VMFS5 datastore you intend to create.

Creating a VMFS3 file system first is unnecessary and would not correctly prepare the disk for VMFS5. Similarly, creating a VMFS5 file system directly with vmkfstools without clearing the existing partitions would likely result in an error or a failed datastore creation. Deleting data using vmkfstools is also not a suitable action, as vmkfstools is used for managing virtual disk files rather than managing disk partitions. Thus, the correct initial step is to delete the existing partitions to ensure a clean
