ROM or Server.
Now either choose Hardware Management Console DVD-ROM or FTP Source. If
having chosen the latter option, provide the servers address or name and your credentials.
In case the suse.ins file is not located in the root directory of the server, provide
the path to this file. Continue to the Select the software to load menu and select the

1.3.4 Load from SCSI-Attached DVD
To IPL from a SCSI DVD, you need access to an FCP adapter connected to a DVD
drive. You need values like the WWPN and LUN from the SCSI drive. For details, see
Section "IPL from FCP-Attached SCSI DVD" (page 19).

1.4 The IOCDS

This section provides some necessary information about the IOCDS and how to cus-
tomize some settings for sharing network cards or DASDs among several LPARs. In
the IOCDS, the chpid and types of the devices connected to the IBM System z are
defined. The resources can be dedicated or shared among LPARs.
WARNING: Sharing Devices (DASD)
Do not share writable DASD among LPARs because this might result in data
loss. Consider the definition of the necessary resources in advance when plan-
ning the setup for SUSE Linux Enterprise Server on IBM System z.
This example shows how to dedicate a DASD to one specific LPAR. This LPAR is
referred to as LPAR1.
Example 1.1 Dedicating DASD to One LPAR
CHPID PATH=FD,TYPE=DSD,SHARED
CNTLUNIT CUNUMBR=FD00,PATH=FD,UNITADD=((00,256)),UNIT=3990-2
