Hi,

It is easy to group CMS and CP into the same box when you are running a
Linux guest.  The hcp command will pass CP commands down to the layer
below you.  The CP command is sent to the host system as if you had
entered it from the virtual machine console.

When you first LOGON to your virtual machine, you have the option of
starting Linux (which you have done) or starting CMS (you probably
had to IPL CMS when you first started setting things up in this virtual
machine).  When you started Linux, you replaced the CMS image that
was running in your virtual machine.  Now, while your virtual machine
is running Linux, the CP layer is still below you... and is shared by all
the other virtual machines who are logged on... but your instance of
CMS has been replaced by an instance of Linux.  If you IPL CMS
while your Linux image is running, CMS will replace Linux and there
will NOT be an opportunity for Linux to write buffers to dasd, etc.
On the next IPL, your Linux system would entertain you with a scan
of your entire minidisk.  It's not much fun after the first five times.

The only commands in your profile exec that would be useful to you
are CP commands.  If you need to do something non-disruptive
with a CP command you could write a bash script to issue
the hcp commands (e.g. "hcp couple 500 to othervm 500").

Hi

Short version of the question:

How do do a "hard-reset" to a linux guest from within linux?

Note that I don't mean to IPL the boot specific device: I need to re-run
profile.exec from cms . I know I can do that using hcp.

(I have an environment in which for some users those things are very
different)

Any pointers to FMs (that answer this) would be appreciated.

Thanks in advance
