There was a question on Twitter this morning from AJ Kuftic on whether it is possible to display the mapping of a VMFS Datastore to its respective storage device using ESXCLI. Josh Coen beat me to the answer this morning, but yes it is possible using ESXCLI. I thought I still share this quick tip as it may not be obvious, especially when you need this information while performing a storage maintenance or troubleshooting with your storage administrator.

For those of you who are familiar with the legacy esxcfg-* commands, this information can be retrieved using the following command:

esxcfg-scsidevs -m

You can also retrieve this same information by using the following ESXCLI command (can be executed remotely as well):

esxcli storage vmfs extent list

As you can see from both screenshots, we can easily identify the name of the VMFS datastore and the specific storage device it is mapped along with other pieces of information. I prefer the ESXCLI method as it is nicely formatted along with the title header for each property.
