► Save your changes with the FILE subcommand:<br />

You could continue to configure the system, but at this time it is recommended that you test<br />
your changes by shutting down and reIPLing the system.<br />
4.5.4 Shutting down and reIPLing the system<br />
You may want to be able to shutdown and reIPL z/<strong>VM</strong> without having to access the HMC.<br />
Often, the HMC will be logged off and thus the Integrated 3270 console (SYSG) will not be<br />
available. Because of these factors it is useful to use the System Console (SYSC - which has a<br />
title of Operating System Messages on the HMC) in order to shut down z/<strong>VM</strong> and reIPL it<br />
without needing to use the console. This console is always accessible whether you are<br />
logged on to the HMC or not. z/<strong>VM</strong> messages during both the shutdown and reIPL process<br />
will be written to the system console, but often you will be able to ignore them - you just want<br />
your system back in a few minutes over the network.<br />
To shut down and re-IPL the system, per<strong>for</strong>m the following steps:<br />
► Pass the parameter IPLPARMS CONS=SYSC to the SHUTDOWN REPIL command:<br />
==> shutdown reipl iplparms cons=sysc<br />
You will lose your session, but it should come back in a few minutes as described above.<br />
► When your system is back up, start a 3270 session and logon as MAINT. This shows that<br />
there is TCP/IP access to z/<strong>VM</strong>.<br />
Important: If you cannot start another 3270 session, do not despair - consider this a good<br />
learning experience :)) You must go back to an Integrated 3270 session from the HMC.<br />
Verify that TCPIP is logged on. If it is logged on and you still can’t get to your system, log<br />
TCPIP off (or just re-IPL CMS), log back on, press Enter and watch the messages <strong>for</strong><br />
errors.<br />
► Query the new VSWITCH:<br />
==> q vswitch<br />
