Chapter 9. Setting up basic system automation
This section covers basic forms of z/VM system automation:
v
Starting and stopping virtual machines automatically
v Automating z/VM system and virtual machine operations through the
programmable operator facility.
Starting and stopping virtual machines automatically
You can start and stop virtual machines manually, but it is more convenient to
have z/VM do these tasks automatically. This topic shows you how to:
v
Start your Linux virtual servers and important virtual machines automatically.
You already configured DirMaint to start automatically in “Steps for
automatically starting DIRMAINT” on page 59, and TCP/IP in “Steps for
automatically starting TCP/IP” on page 63. Now you will do the same for other
virtual machines.
By including the CP XAUTOLOG command in the AUTOLOG1 virtual
machine’s PROFILE EXEC, a virtual machine starts automatically when z/VM is
loaded (IPL). The AUTOLOG1 user ID is the default user that z/VM logs on at
IPL time. When logged on, AUTOLOG1 executes its PROFILE EXEC, which can
contain an XAUTOLOG command to start a virtual machine that runs Linux or
any other vital system service. In turn, each virtual machine executes its own
PROFILE EXEC, which contains the necessary commands to establish its
operating environment; in the case of Linux, the PROFILE EXEC can load the
Linux operating system (see “(Optional) Steps for loading Linux automatically at
logon” on page 82.)
v
Stop Linux virtual servers automatically. You can enable Linux to perform an
orderly shutdown whenever you shut down z/VM or force the Linux virtual
machine to log off with the FORCE command. Because Linux shuts down
gracefully, Linux does not have to examine or repair disks when rebooting.
Additionally, Linux can notify network monitors that it is shutting down.
Prior to shutting down or forcing a virtual machine to log off, z/VM sends a
signal to enabled virtual machines to shut down. The SYSTEM CONFIG file sets
the amount of time that z/VM allows a virtual machine operating system to
process a shutdown signal. In this topic, you configure Linux to process a
shutdown signal.

Steps for automatically starting Linux virtual servers and
other virtual machines
This procedure configures the AUTOLOG1 virtual machine to startup virtual
machines automatically whenever z/VM starts.
Before you begin: You need to log on as MAINT.
