When running a penguin farm under z/VM what tools can one use to:
1. schedule the startup of the guests after a z/VM IPL?
2. schedule an orderly, clean, shutdown of all guests for a planned z/VM
IPL?

Under VM, the standard way
For SHUTDOWN,
one thing that helps is to have a root shell running
on the virtual machine console. This would bypass Linux's
sign-on mechanism, but presumes you are covered by VM's sign-on
(which is true in this case). With that, you can code some REXX
to do the CP SEND to initiate a shutdow

One can use the usual AUTOLG exec on OPERATOR's 191 mdisk, or the
AUTOLOG1 svm to start up guests is a controlled way. If you'

Ah - so that begs the question - how do you have a root shell running on
the console without signing on first?

You could change the /etc/inittab to actually start up a root shell on
the console rather than some getty program.

Its best to have a sign in process run just to set up the environment but
running a straight /bin/sh as root from /etc/inittab is quite possible if
you want to do it that way. You ma

It creates a PAM session so there is a security identity and the fact the
console was logged in as root is in the logfiles.

No, it will work, but SAF will not be aware of it or manage it in any way.
If you do it manually, it'll work, but I don't make any guarantees about
SAF's ability to cope with manual changes outside it's purview.

UNIX (here meaning HPUX, Solaris, AIX, so forth) treats the
console just like any other terminal, requiring authentication.
Linux does the same thing. VM treats the con
