After updating the VCSA appliance, not able to unmount the ISO with the above error.
Are there any commands in Photon OS to do this cleanly?
If not, is the only way to get around the issue is to log directly into the ESXi Host and override the lock:
"The guest operating system has locked the CD-ROM door and is probably using the CD-ROM, which can prevent the guest from recognizing media changes. If possible, eject the CD-ROM from inside the guest before disconnecting. Disconnect anyway and override the lock?"
