Accessing the virtual terminal on IVM managed hosts

Virtual clients running on a IVM (Integrated Virtualization Manager) do not have a direct atached serial console nor a virtual window which can be opened via an HMC. So how do you access the console?

You can log on as the padmin user on the VIOS which is serving the client you want to logon to its console. Just log on to the VIOS, switch to user padmin:

# su - padmin
Then run the lssyscfg command to list the available LPARs and their IDs on this VIOS:
# lssyscfg -r lpar -F name,lpar_id
Alternatively you can log on to the IVM using a web browser and click on "View/Modify Partitions" which will also show LPAR names and their IDs.

Use the ID of the LPAR you wish to access:
# mkvt -id [lparid]
This should open a console to the LPAR. If you receive a message "Virtual terminal is already connected", then the session is already in use. If you are sure no one else is using it, you can use the rmvt command to force the session to close.
# rmvt -id [lparid]
After that you can try the mkvt command again.

When finished log off and type "~." (tilde dot) to end the session. Sometimes this will also close the session to the VIOS itself and you may need to logon to the VIOS again.
