Re: autostart s390x



Hi,

Yesterday, there was maintenance at Marist [1], but unfortunately our worker didn't come up after it. This apparently is just a matter of configuration. I recall we discussed this in the past and thought you configured it already to autostart. Can you (help me to) check if the settings are correct?

Finally found some time to swap my knowledge back in and check.

I confirmed that it wasn't enabled before (a second add fails). This logs on the VM when z/VM starts up.

This means it's currently set to load CMS instead of Linux.

This sets the VM to boot from disk 150 on startup.

So that looks good, it directly booted into Linux. But then it misses CP initialization commands like "don't wait for every page of Linux's output", so it's probably still better to boot through CMS with the drawback that to get into CMS one has to do "ACCESS (NOPROF" after "IPL CMS" to skip loading PROFILE EXEC.

The new PROFILE EXEC:

CP LINK TCPMAINT 592 592 RR
ACCESS 592 T
CP TERM MORE 0 0
CP SET RUN ON
CP IPL 150

That seems to have done my bidding.
