Info

– DASD: 27 3390-3s or 9 3390-9s at a minimum – Open Systems Adapter (OSA) network cards: One card minimum with 8 device numbers (technically 6, but OSA “triplets” usually start on an even address). Two OSA Express cards with eight device numbers on one and four on the other is recommended for high availability. ► A network-attached computer that will act as an NFS server and possibly an FTP server with at least 6 GB of disk space Setting up a Linux PC or UNIX® server is described. If you only have access to a Windows machine, AllegroNFS has been suggested as an NFS server. See http://nfsforwindows.com/home ► A workstation or desktop that has network access to the mainframe 2.1.2 Software resources The following software resources are needed: ► z/VM 6.1 install media with documentation. The physical media of DVDs is described. In addtion, there are now sections describing how to use electronic delivery of z/VM utilizing an FTP server, such that physical media is not needed. ► RHEL 6 Linux install media. If you do not have it, you can request a free 180-day evaluation copy at: http://www.redhat.com/z See section 6.3, “Setting up a RHEL 6 install tree” for details. ► An operating system for the NFS server ► The code associated with this book - on the Web at: ftp://www.redbooks.ibm.com/redbooks/SG247932/SG247932.tgz ► Tools on the workstation and desktop: – A 3270 Emulator such as Attachmate Extra, Hummingbird Host Explorer, or IBM Personal Communications for Windows desktops – A Linux SSH client such as PuTTY (recommended) or TeraTerm – A VNC viewer These resources are described in more detail in the chapters that follow. 2.1.3 Networking resources The following network resources are needed: ► A TCP/IP address for z/VM ► One TCP/IP address for each Linux virtual server ► Associated TCP/IP information: – DNS host name – DNS domain – DNS server TCP/IP address – TCP/IP gateway – TCP/IP subnet mask – TCP/IP broadcast address (usually calculated from address and subnet mask) – TCP/IP MTU size 8 The Virtualization Cookbook for RHEL 6
The TCP/IP addresses must be routed to the OSA card(s). 2.2 z/VM conventions It is good to use conventions so that you and others can recognize z/VM resources by their names. This section discusses conventions for DASD volume names and backup file names. 2.2.1 Volume labeling convention You should have a convention for labeling DASD. Your shop may already have a labeling convention which will largely determine the labels to be given to the DASD used by your z/VM and Linux LPAR. Each System z DASD is addressed with a device number consisting of four hexadecimal digits. Each System z DASD has a six character label. It is convenient to include the four-digit address in the label so that you can easily tell the address of each DASD from its label. When followed, this convention guarantees that no two DASDs will have the same label. This can be an important issue especially when z/OS® has access to the DASD. Sometimes DASD is shared among LPARs in which case your z/VM LPAR can see DASD owned by other LPARs. In this situation, it is convenient to identify the LPAR that owns the DASD. Therefore the volume labeling convention used in this book identifies the LPAR with the first character. That leaves the second character in the label to identify the basic function of the DASD. The LPAR used in this book is identified by the character M. The following characters are used for the types of DASD in the second character of the label: M Minidisk space (PERM) P Paging space (PAGE) S Spool space (SPOL) T Temporary disk space (TDISK) V z/VM operating system volumes For example, Figure 2-1 shows the labeling convention for the DASD in LPAR M, of type minidisk at real address A700. M M A 7 0 0 Real address DASD type - Minidisk or PERM space LPAR identifier Figure 2-1 DASD labeling convention The letter M is hard-coded into REXX EXECs that adopt this convention. If you want a different LPAR identifier character, they can easily be changed (search for the firstChar variable). Chapter 2. Planning 9
