I am installing SLES 12 and need to modify zipl.conf like I did with previous versions of SLES and found that /etc does not contain file zipl.conf.
Specifically, I need to add ‘vmpoff=LOGOFF’ to the parameters so that Linux will logoff the z/VM guest when it terminates.
I’ve searched the internet and several of the SLES 12 manuals and can only find entries similar to ‘modify /etc/zipl.conf …’. I searched SLES 12 for ‘zipl.conf’ and found a sample file. Can I simply copy /usr/share/doc/packages/s390-tools/zipl.conf.sample to /etc/zipl.conf and start from there? Is there a way to display the zipl options in effect to verify that the sample matches what is running?
