Enable Local or Remote Tech Support Mode TSM from vSphere Client

Tech Support Mode or TSM is a sort of simple version of the system console that was available on the classic versions of ESX. Except that the TSM mode is not Linux based and does not have all the capabilities that the old COS had. But you can now access Tech Support Mode locally or via SSH if you follow the instructions below to enable them.

  5. Verify that the daemon selected in step 3 shows as running in  the Services Properties window.
