Chapter 7. Installing RHEL 6 on the cloner 111

6. Verify that the RHEL6 EXEC file has the correct information. Note the kernel and RAM disk

have hardcoded file names (RHEL6), but the file name of the parameter file will be the user

ID (userid() function) of the user running the EXEC:

==> type rhel6 exec d

/* EXEC to punch a RHEL 6 install system to reader and IPL from it */

Address 'COMMAND'

'CP SPOOL PUN *'

'CP CLOSE RDR'

'CP PURGE RDR ALL'

'PUNCH RHEL6 KERNEL * (NOHEADER'

'PUNCH' Userid() 'PARM-RH6 * (NOHEADER'

'PUNCH RHEL6 INITRD * (NOHEADER'

'CP CHANGE RDR ALL KEEP'

'CP IPL 00C CLEAR'

7. There are two text files that are needed to install RHEL 6: a parameter file and a

configuration file. A sample parameter file is provided and is named SAMPLE PARM-RH6. It

has some values, the most important value of which, the

CMSCONFFILE variable, points to the

configuration file that remains on a CMS minidisk. Copy the sample parameter file to a

new file named RH6CLONE. Change the configuration file variable to point to a file with the

same file name:

==> copy sample parm-rh6 d rh6clone = =

==> x rh6clone parm-rh6 d

root=/dev/ram0 ro ip=off ramdisk_size=40000

CMSDASD=191 CMSCONFFILE=RH6CLONE.CONF-RH6

vnc vncpassword=lnx4vm

8. Copy the sample configuration file and modify the appropriate fields. Refer to the

worksheet in 2.7.4, “Linux user ID worksheet” on page 18. Here are the values used for

the example in this book.

==> copy sample conf-rh6 d rh6clone = =

==> x rh6clone conf-rh6

DASD=100-105,300-301

HOSTNAME=gpok223.endicott.ibm.com

NETTYPE=qeth

IPADDR=9.60.18.223

SUBCHANNELS=0.0.0600,0.0.0601,0.0.0602

NETMASK=255.255.255.128

SEARCHDNS=endicott.ibm.com

GATEWAY=9.60.18.129

DNS=9.0.3.1

MTU=1500

PORTNAME=DONTCARE

PORTNO=0

LAYER2=0

Note: The RHEL 6 installer supports OSA/NIC in layer 2 (Ethernet) mode. In the

example above, the Linux virtual machine is connecting to a layer 3 VSWITCH, so the

parameter LAYER2=0 is set. When connecting in layer 2 mode, set LAYER2=1. Then, if this

guest is connected to a VSWITCH, set VSWITCH=1, signifying that the VSWITCH will

provide the MAC address. If this guest is not connected to a VSWITCH, set VSWITCH=0

and add the parameter MACADDR= followed by the MAC address for this guest.
