These changes will not take effect until the next IPL, so you must grant this user ID access to
the VSWITCH for this z/VM session. This is done as follows:
==> set vswitch vsw1 grant rh6clone

7.1.3 Preparing RH6CLONE bootstrap files
To IPL a RHEL 6 installation system, four bootstrap files must be prepared. Three are
punched to z/VM reader and then IPLed. These three files IPLed are a kernel, a parameter
file and an initial RAMdisk. The fourth file is a configuration file stored on a CMS disk that the
parameter file points to.
Think of these as the files that are on as a PC Linux boot CD (or floppy disk). Also, a small
REXX EXEC is commonly used to clean out the reader, punch the three files and IPL the
reader. A sample RHEL 6 parameter file, configuration file and install EXEC are supplied and
should be on the LNXMAINT 192 disk (this task is in section 4.7.5, “Copying files associated
with this book to LNXMAINT” on page 60). Therefore, only the kernel and RAMdisk need to
be copied.
► Start an SSH session as root on the NFS server.
► Use the ftp command to copy the RHEL 6 kernel and initial RAMdisk to LNXMAINT’s D disk.
These files must have a record format of fixed 80 byte records. This format can be set with
the site fix 80 FTP subcommand (if this subcommand fails, try quote site fix 80).
Following is an example:
# cd /nfs/rhel6/dvd1/images
# ftp 9.60.18.249
Name (9.60.18.249:root): lnxmaint
Password:
230 LNXMAINT logged in; working directory = LNXMAINT 191
Remote system type is z/VM.
ftp> cd lnxmaint.192
250 Working directory is LNXMAINT 192
ftp> site fix 80
200 Site command was accepted.
ftp> bin
200 Representation type is IMAGE.
ftp> put initrd.img rhel6.initrd
