Based on [WayBack] windows – How to run batch file command with elevated permissions? – Super User:
powershell -command "Start-Process cmd.exe -Verb runas"
This works better than "runas /user:administrator cmd.exe" as that forces to use the specific Administrator account, whereas the PowerShell way allows you to specify the actual account during elevation.

Reminder to self when checking “new” disks to see what partitions they contain before formatting them as VMFS.
There is a truckload information at [WayBack] Using the partedUtil command line utility on ESXi and ESX (1036609) | VMware KB.
A few tips; example output is further below:
/vmfs/devices/disks/ where there are two entries per device: a path leading to the device, and a link to that path which starts with vml. which I filter out with grep./vmfs/devices/disks/ ends with :# where # is a number, then it is a partitionpartedUtil get as partedUtil getptblwill give you exactly the same information,
unknown: the disk has no partition table yet (usually), or the type of partition table cannot be determined (hardly)gpt: there is a GUID Partition Tablemsdos: there is a Master Boot Record partition tablepartedUtil is unformatted, which means it is easy to parse, but hard to read for humans. You can pipe through sed 's/ /\t/g' (as there is no tr on the ESXi busybox)On scripting:
sh (always been there)Python (ESXi 5.1 has Python 2.7.8; ESXi 6.5 has Python 3.5.3; it has likely been available in earlier versions too).On device names:
On errors:
Module 'Disk' power on failed.(in the vmware.log file for the VM) and LookupAndOpen[file] failed Click here for more details. (in the Web UI): my impression this is usually has to do with either a mismatch of the text vmdk and the binary backing, or the chain of snapshots. The odd thing is that vmkfstool doesn’t always catch this and just returns Disk is error free.vmkfstools -x check /path/to/vmname.vmdk followed by vmkfstools -x repair/path/to/vmname.vmdk
unknown, but for which VMware doesn’t know what to do with it. Basically three things to try:

Some interesting links about the various VMFS types:

traceroute now, this is not needed any more: [WayBack] Poor man’s traceroute for ESXi | virtuallyGhetto (https://github.com/leonidg/Poor-Man-s-traceroute/blob/master/traceroute.py needs to be updated to be compatible with Python 3 anyway).
Example outputs on one of my systems, of which I stripped most of the disks as they’re not really relevant here.

Interesting read and watch:
At the recent Embedded Linux Conference and OpenIoT Summit, Mozilla Technical Evangelist Dietrich Ayala proposed a simple and affordable solution to home automation: A discarded smartphone can handle some of the most useful home automation tasks without requiring expensive hubs and sensors — or risking data security in the cloud.
