Common Steps Needed for Installing Red Hat Linux to a VM or LPAR

• Set up an FTP, HTTP, or NFS server on a different machine. This server is referred to as RPMSERVER throughout the rest of this document.

• Set up this server to export the directory which contains the RedHat directory and verify that this is working. (Important NOTE: the directory specified in the following examples refers to /the/directory/containing/RedHat. This means it is the directory up to, but NOT including, the RedHat distibution directory. For example, if you have a Red Hat Linux 7.1 cd mounted at /mnt/cdrom on you host machine, /the/directory/containing/RedHat directory would be /mnt/cdrom. This goes for NFS, FTP, and HTTP installs.)

  • Install via NFS

    	Note
    	At the time of printing, NFS installations using the IBM 64 bit zSeries kernel are highly unstable. HTTP or FTP installations are recommended.

    • Configure /etc/exports by adding the following line:

      /the/directory/containing/RedHat Your.S390.IP.Address(rw,no_root_squash)

      	Note
      	This has been broken into two lines for easier reading.

      It is important to specify the IP Address of the S/390 virtual machine that will be connecting to this NFS server.

    • Alternatively you may specify (on some NFS systems):

      /the/directory/containing/RedHat *(rw,no_root_squash)

      This will allow anyone to mount the RedHat install system.

    • Restart the NFS daemon (on a Red Hat Linux machine, use /sbin/service nfs restart) to force NFS to reload the /etc/exports file.

    • Attempt to mount the directory exported to a temporary directory and view its contents following this example:

      • mkdir /mnt/mytemp

      • mount -o rw,rsize=8192 -t nfs /whatever/s390-root /mnt/mytemp

      • cd /mnt/mytemp

      • ls — allows you to view the contents of /mnt/mytemp.If you do not see the RedHat directory, then wrong path was mounted and/or exported.

      • umount /mnt/mytemp

  • Install via FTP

    • If there will be no access to the internet from the S/390, you may setup an anonymous FTP server on a machine in your local network. Be sure not to conflict with any firewall restrictions.

  • Install via HTTP

    • Alternatively you may setup an internal HTTP server.

  Note

  When booting the installation program, several warning messages may appear regarding module mismatches and may be ignored. These warnings are caused by the Red Hat Linux kernel loading of the closed source, binary only network drivers supplied by IBM. Further, if using the binary only drivers, an error message may also appear that orginates from the channel device layer. It states, chandev_exec_start_script failed, and may be ignored.
