All information found in this book has been compiled with utmost attention to detail. However, this does not guarantee complete accuracy. [. . . ] 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).

The example shows the directory for a user LINUX1 with the password LINPWD, 256 MB of memory (extendable up to 512 MB), 32 MB of expanded RAM (XSTORE), some minidisks (MDISK), two CPUs and an OSA QDIO device. TIP: Assigning Memory to z/VM guests When assigning memory to a z/VM guest, make sure that the memory size suits the needs of your preferred installation type. See Section "Memory Requirements" (page 12). Preparing for Installation 27 Example 2. 2 Configuration of a z/VM Directory USER LINUX1 LINPWD 256M 512M G *____________________________________________ * LINUX1 *____________________________________________ * This VM Linux guest has two CPUs defined.

Minidisk 150 with 200 cylinders is the Linux swap device. Disk 151 with 2800 cylinders holds the Linux installation. Now add (as the user MAINT) the guest to the user directory with DIRM FOR LINUX1 ADD. Enter the name of the guest (LINUX1) and press F5 . Set up the environment of the user with: DIRM DIRECT DIRM USER WITHPASS The last command returns a reader file number. This number is needed for the next command: RECEIVE <number> USER DIRECT A (REPL) 28 Architecture-Specific Information Assign the directories to the guest with DIRMAP USER DIRECT A. You can now log in on the guest as user LINUX1. Proceed with Section 2. 4. 2, "z/VM Installation" (page 30). 2. 4 IPLing the SUSE Linux Enterprise Server Installation System 2. 4. 1 LPAR Installation There are different ways to IPL SUSE Linux Enterprise Server into an LPAR. The preferred way is to use the Load from CD-ROM or server feature of the SE or HMC. IPL from CD-ROM Mark the LPAR to install and select Load from CD-ROM or server. Leave the field for the file location blank or enter the path to the root directory of the first CD-ROM then select continue. In the list of options that appears, choose the default selection. Operating system messages should now show the kernel boot messages. IPL from ESCON or FICON Attached Tape If you cannot IPL from CD-ROM, create a channel attached tape from which to IPL the SUSE Linux Enterprise Server installation image. Use the LOAD button in the SE or HMC with the tape device address as the load address to IPL the SUSE Linux Enterprise Server installation system. There are many ways to create an IPLable tape. One is to copy the files: /boot/tapeipl. ikr /boot/parmfile /boot/initrd as binary files from CD 1 (for example, using FTP from a Linux workstation). [. . . ] For WriteChannel, enter the number of the WRITE channel. For Portname, enter an appropriate port name. Make sure that the READ channel carries an even device number. · Interface hsi for HiperSockets and VM guest LANs: ReadChannel=0. 0. 0624 WriteChannel=0. 0. 0625 DataChannel=0. 0. 0626 For ReadChannel, enter the appropriate number for the READ channel.
