Using the terminal applets on the HMC

Ubuntu 22.04 LTS LPAR mode z/VM guest

You should be aware of some aspects of the line-mode and the full-screen mode terminal when using the corresponding applets on the HMC.

The following statements apply to both the line-mode terminal and the full-screen mode terminal on the HMC:

  • On an HMC, you can open each applet only once.
  • Within an LPAR, there can be only one active terminal session for each applet, even if multiple HMCs are used.
  • A particular Linux® instance supports only one active terminal session for each applet.
  • Slow performance of the HMC is often due to a busy console or increased network traffic.
The following statements apply to the full-screen mode terminal only:
  • Output that is written by Linux while the terminal window is closed is not displayed. Therefore, a newly opened terminal window is always blank. For most applications, like login or shell prompts, it is sufficient to press Enter to obtain a new prompt.
  • The terminal window shows only 24 lines and does not provide a scroll bar. To scroll up, press Shift+PgUp; to scroll down, press Shift+PgDn.
Security hint: Always end a terminal session by explicitly logging off (for example, type exit and press Enter). Simply closing the applet leaves the session active and the next user to open the applet resumes the existing session without a logon.
