RedHat, SUSE, Oracle Enterprize Linux OS Images

This section describes special requirements for RedHat and SuSE OS images:

• The earlier Linux installations which the ITCM OSIM supports work with DOS osinstal.2,3 boot images.
• The new Linux installations which the ITCM OSIM supports work only with the Linux-based (customized CentOS 6.3 x64) boot image.
• For Linux distributions not including a loadlin.exe you have to acquire it from the internet and install it.

  Note: There are many places in the internet where you can download loadlin.exe and also many sites where the functionality and the installation of loadlin is documented. For example, see article "Loadlin" in the Wikipedia.

• Linux installations load the setup files from the Boot Server using a NFS share or TFTP.
• The Linux packages will be read from an NFS share.

  The NFS share is on the boot server but can alternatively be on a central NFS server.

  Depending on the preferred solution, the boot server or the central NFS server needs NFS running. On Windows, the “NFS Services” can provide the NFS server functionality.

• “NFS Services” must be installed on the server before creating or distributing the images.
• If the customer wants to have the Linux files and the NFS share on boot servers instead of the central NFS server, CreateOSImage or the wizard must be used without the –a option to create the LINUX image.

  CreateOSImage then inserts all files from the Linux CDs into the new OS-image. It also creates an NFS share with the sufficient access rights.

  RegisterOSImage then builds a Software Delivery package with the complete OS-image files. When distributing this Software Delivery package to a boot server, the installation procedure will copy all Linux files to the boot server and the installation will create a new NFS share.

• It is also possible to use an external NFS server (which is not the Boot Server).

For RHEL6 OS Image Creation:

When you use the Local or Network folder option in the OS image creation, ensure that the accessed folder has the following steps:

• RHEL6 ISO image is copied in to the folder and renamed to cd1.iso
• Copy the images folder from the RHEL6 ISO  in to  this folder
• Create a directory named  Packages and copy the file Red_Hat_Enterprise_Linux-Release_Notes-6-en-US-3-7.el6.noarch.rpm from the Packages folder in the ISO.

  The version of the RPM package changes with RHEL6 updates.

• Copy the .discinfo file from the ISO image in this folder

  The directory structure is in the following format:

  SharedFolder\cd1.iso

  SharedFolder \images

  SharedFolder \ Packages\ Red_Hat_Enterprise_Linux-Release_Notes-6-en-US-3-7.el6.noarch.rpm

  SharedFolder \.discinfo
