How to mount an ISO to an ESXi Host

I was recently working on and issue in an environment that required me to mount an ISO to an ESXi host.

To access the contents of a CD or ISO within your ESXi Host perform the following:

1. Mount the ISO using iDRAC / iLO etc.
2. Console into the ESXi host and run the following to load iso9660:

vmkload_mod iso9660

3. To find the path to the CD ROM drive run the following:

esxcfg-mpath -l | grep -i cd-rom

4. Run the following to mount the CD-ROM drive:

vsish -e set /vmkModules/iso9660/mount <devicename>

5. You will now be able to see the contents of the CD- Rom in /vmfs/volumes/.  In my case, the ISO I mounted was named "20180215":

6.  Once you're done unmount the CD/ISO with the following:

vsish -e set /vmkModules/iso9660/umount <devicename>

7. To unload the iso9660 module":

vmkload_mod -u iso9660

On a similar note, I've had a lot of success using the following application to create ISOs from files/folders:
