Download Red Hat LINUX VIRTUAL SERVER 4.6 - ADMINISTRATION Installation manual

Figure 1-1 shows a block diagram of a System z10 with multiple LPARs. z/VM V5.4 is
installed in one of these LPARs. z/VM comes with many user IDs predefined. The most
important six IDs are shown in the z/VM LPAR above the dashed line. Below the dashed line,
you see the user IDs described in this book.
Figure 1-1 System infrastructure and z/VM user IDs
The user IDs that are described in this book have the following functions:
򐂰 LNXMAINT: A user ID on which to store files that will be used by both CMS and Linux.
򐂰 RH6CLONE: The cloner that does the cloning. It also serves as the Linux install server,
and has other functions.
򐂰 LINUX01-04: The user IDs to which you clone. Each virtual server is configured with two
3390-3 minidisks to allow for slightly more than 4 GB of space.
򐂰 RH6GOLD: The RHEL 6 golden image. This is the Linux system that is cloned.
1.5 Usability tests performed for this book
During the writing of this book, many usability tests were conducted. The participants had a
variety of skills, but none had both Linux and z/VM system administration skills. By the end of
the first day of all of the formal tests, most participants had all completed up to and including
Chapter 5, “Servicing z/VM” on page 73, so z/VM was installed, serviced, and customized for
TCP/IP communications with a highly available VSWITCH. By the end of the second day,
most participants had cloned their first Linux virtual server. You should be able to complete
most steps in the book in four solid days of work, if all goes well.
