- Using a set of CD-ROMs, or a DVD — Create ISO image files from each installation CD-ROM, or from the DVD. For each CD-ROM (once for the DVD), execute the following command on a Linux system:
dd if=/dev/cdrom of=/tmp/file-name.isoThis command may raise an error message when the data at the end of the CD-ROM is reached which can be ignored. The ISO images created can now be used for installation, once copied to the correct DASD.
- Using ISO images - transfer these to the system to be installed (or to the correct DASD or SCSI devices).Verifying that ISO images are intact before you attempt an installation, helps to avoid problems. To verify the ISO images are intact prior to performing an installation, use an
md5sumprograms are available for various operating systems). An
md5sumprogram should be available on the same Linux machine as the ISO images.Make the correct DASDs or SCSI LUNs accessible to the new VM or LPAR, and then proceed with installation.Additionally, if a file called

anaconda, the installation program. Refer to the file
