2.3 Preparing the IPL of the SUSE
Linux Enterprise Server
Installation System
2.3.1 LPAR Installation
Configure your IBM System z system to start in ESA mode with an appropriate activa-
tion profile and IOCDS. Consult IBM documentation for more about how to achieve
this.
IOCDS: Attaching and Configuring Devices
A SUSE Linux Enterprise Server installation needs at least two devices: a DASD and
a network connection device. For an IPL from tape, a tape device should also be acces-
sible. Devices are configured and attached to an LPAR in the IOCDS (input output
configuration data set). This example defines one DASD, one OSA-2 network device,
and a tape device for LPAR Z1. For further information about how to set up the IOCDS
for Linux, refer to IBM hardware documentation of your machine (
http://www
.s390.ibm.com/linux/press.html
).
