112 z/VM and Linux on IBM System z: The Virtualization Cookbook for Red Hat Enterprise Linux 6.0

9. Linux user IDs will obtain their PROFILE EXEC file from LNXMAINT 192. This file runs

when you press Enter at the VM READ prompt. It creates two VDISKs with the SWAPGEN EXEC

file, which will be used later to swap spaces. It also performs a few other functions,

including performing an IPL of Linux automatically if the virtual machine is logged on

disconnected. You can view the contents of the PROFILE EXEC file by running the CMS

TYPE command:

==> type profile exec d

/* PROFILE EXEC for Linux virtual servers */

'CP SET RUN ON'

'CP SET PF11 RETRIEVE FORWARD'

'CP SET PF12 RETRIEVE'

'ACC 592 C'

'SWAPGEN 300 524288' /* create a 256M VDISK disk swap space */

'SWAPGEN 301 1048576' /* create a 512M VDISK disk swap space */

'PIPE CP QUERY' userid() '| var user'

parse value user with id . dsc .

if (dsc = 'DSC') then /* user is disconnected */

'CP IPL 100'

else /* user is interactive -> prompt */

say 'Do you want to IPL Linux from minidisk 100? y/n'

parse upper pull answer .

if (answer = 'Y') then 'CP IPL 100'

end /* else */

7.1.4 Beginning the Linux installation

Perform the following steps to begin the Linux installation:

1. Log on to RH6CLONE. The PROFILE EXEC file from the LNXMAINT 192 disk should prompt

you to perform an IPL of minidisk 100. Because 100 is not installed yet, answer no.

2. Set the memory size to 1 GB with the CP DEFINE STORAGE command:

==> def stor 1g

00: STORAGE = 1G

00: Storage cleared - system reset.

3. Perform an IPL of CMS, and again answer no:

==> ipl cms
