When encountering a failed vSphere Web Client task during the creation of a VMFS datastore, deleting the partitions with partedUtil is a practical solution. This approach is effective because it allows for the removal of any existing partition that might cause conflicts when trying to create a new VMFS datastore.

Conflicts can arise when there are remnants of previous datastores or unsupported filesystems still present on the storage device. By using partedUtil, you can precisely manage the partitions on the storage device, ensuring that they are cleared before attempting to create the VMFS datastore again. This method directly addresses potential blockages that stem from existing partitions, allowing for a clean slate for the new datastore creation process.

Creating a VMFS5 filesystem with esxcli, while it can be a valid method after ensuring partitions are correctly set, does not resolve existing partition issues if they exist. Similarly, creating a VMFS3 filesystem first or trying to delete data with vmkfstools would not address underlying partitioning conflicts that could prevent successful datastore creation. Hence, managing partitions effectively with partedUtil is the most direct route to resolving the failed task.
