Create OSIM OS Images which Installs Packages From an External NFS Server

1. Verify that the Linux distribution is available in ISO format. Rename the original ISO image file names in the distribution to cd1.iso, cd2.iso, ..., cd<n>.iso.
2. Create a share on the external NFS server and copy the ISO images from the OS CDs or DVD. The NFS share must contain at least all .iso files of the distribution, from cd1.iso to cd<n>.iso.
3. For the user "anonymous logon", grant read access to the shared directory and the .iso files in that directory on the NFS share. For more information, see the section Set Access Rights to External NFS READHATES5x and SUSE102 Shares.
4. Depending on whether you want to create the OS Image from the CDs/DVD, or from a directory structure, execute one of the following commands:

CDs or DVDs

• For RedHat Enterprise Linux

  CreateOSImage -I <name> -o <REDHATES50(x64)-CD or REDHATES50(x64)-DVD> -a <NFS share name>
  

• For SuSe Linux Enterprise Server

  CreateOSImage -I <name> -o <SUSE102(x64)-CD or SUSE102(x64)-DVD -a <NFS share name>
  

  NFS share name

  Specifies the name for the external NFS share.

  The command reads the setup files from CD1 or DVD1 and stores the files on the Image Prepare System / Boot Server.

Directory Structure

• For RedHat Enterprise Linux

  CreateOSImage -I <name> -o <REDHATES50-CD or REDHATES50-DVD> -s < distribution files path> -a <NFS share name>
  

  Distribution files path

  Specifies the path to the directory that includes at least the directory images\pxeboot\.discinfo and the rpm package Server\syslinux*.rpm from CD1 or DVD1.

• For SuSe Linux Enterprise Server

  CreateOSImage -I <name> -o <SUSE102(x64)-CD or SUSE102(x64)-DVD> -s < distribution files path> -a <NFS share name>
  

  Distribution files path

  Specifies the path to the directory that includes at least the setup files boot\* and the rpm package suse\i586\syslinux*.rpm (for 32-bit) or suse\x86_64\syslinux*.rpm (for 64-bit) from CD1 or DVD1. For more information about the folder structure, see Merging the Files from SUSE CDs or DVDs.

  NFS share Name

  Specifies the name for the external NFS share.

Note: If you do not provide the syslinux*.rpm package, you must add syslinux.com later. For more information, see the section Adding Syslinux.com to the OSIM image.

Merging the Files from SUSE CDs or DVDs

Before creating the SUSE OS images, merge the files into a specific structure. The structure varies depending on the version of SUSE and the architecture.

Note: After merging the files, copy the parent SUSE folder to the NFS share.

Creation of SUSE OS Images

The NFS share must contain the merged CDs or DVDs of the Linux distribution for SUSE versions 10 and 11, which is delivered on several CDs or DVDs.

Follow these steps:

1. Merge the files and directories from the CDs or DVDs into one directory called suse. When merging the CDs or DVDs, start from the last CD or DVD so that CD1 or DVD1 is the last to be merged. For more information about the folder structure, see Merging the Files from SUSE CDs or DVDs.
2. Copy the suse directory to the NFS share.
