Ipl Options - Novell LINUX ENTERPRISE SERVER 10 SP3 - ARCHITECTURE-SPECIFIC Supplementary Manual

1.3 IPL Options

This 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 DVD-ROM or server options are discussed.
Installing the software packages, which is done over the network, does not require the
IPL medium.
1.3.1 ESCON or FICON Attached Tape
IPLing 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 to
run) is allowed to access the tape unit. For this, the IODEVICE statement in the IOCDS
must have the attribute SHARED or PART=<LPARName>.
1.3.2 VM Reader
To IPL from a VM reader, transfer the necessary files into the reader first. Then multiple
IPLs are easily done. This is the preferred way on z/VM. For convenience of adminis-
tration, it is recommended to create a user linuxmnt that owns a minidisk with the
files and scripts needed for IPL. This minidisk is then accessed read-only by the Linux
guests.
1.3.3 Load from CD-ROM or Server
For IPLing into an LPAR, it is possible to either load the kernel image directly from
the SE's or the HMC's DVD-ROM device or from any remote system accessible through
FTP. This function can be performed from the HMC. The installation process requires
a file with a mapping of the location of the installation data in the file system and the
memory locations where the data is to be copied. For SUSE Linux Enterprise Server
this file is called suse.ins and located in the root directory of the file system on the
DVD 1.
In the left navigation pane of the HMC expand Systems Management and Servers and
select the mainframe system you want to work with. Choose the LPAR where you want
to boot SUSE Linux Enterprise Server from the table of LPARs displayed in the upper
