1.2.1 LPARIf you install SUSE Linux Enterprise Server for IBM System z into a separate logicalpartition (LPAR), allow SUSE Linux Enterprise Server to use a special part of physicalmemory in your system. Also decide how many processors are used by SUSE LinuxEnterprise Server. In this mode, you can run different operating systems simultaneouslyon your IBM System z system.1.2.2 z/VMRunning SUSE Linux Enterprise Server for IBM System z in z/VM means that SUSELinux Enterprise Server is a guest system within z/VM. An advantage of this mode isthat you have full control over SUSE Linux Enterprise Server from z/VM. This is veryhelpful for kernel development or kernel-based debugging. It is also very easy to addor remove hardware to and from Linux guests. Creating additional SUSE Linux Enter-prise Server guests is simple and you are able to run hundreds of Linux instances simul-taneously.1.3 IPL OptionsThis section provides the information needed to do an IPL for the first installation.Depending on the type of installation, different options need to be used. The channel-attached tape, VM reader, and load from CD-ROM or server options are discussed.Installing the software packages, which is done over the network, does not require theIPL medium.1.3.1 ESCON or FICON Attached TapeIPLing from a channel-attached tape is possible on all systems connected to a tape li-brary. The only prerequisite is that the LPAR in which to install (or allowing z/VM torun) is allowed to access the tape unit. For this, the IODEVICE statement in the IOCDSmust have the attribute SHARED or PART=.16 Architecture-Specific Information
