The Virtualization Cookbook for SLES 10 SP2 - z/VM - IBM

Chapter 9. Configuring RHEL 6 for cloning
It has become appallingly obvious that our technology has exceeded our humanity.
--Albert Einstein
At this point you have completed the install of RH6CLONE, the Linux cloner, and RH6GOLD, the
golden image. The cloner must be up and running. In this chapter, you perform the following
steps:
► “Formatting DASD for minidisks” on page 145
► “Defining a new user ID for a virtual server” on page 146
► “Cloning a virtual server manually” on page 147
► “Cloning one new virtual server” on page 152
► “Defining three more virtual machines” on page 157
► “Reviewing system status” on page 160
9.1 Formatting DASD for minidisks
In section 4.6.2, “Formatting DASD for minidisks” on page 52, DASD was formatted to
become minidisks for the cloner and the golden image. The CPFMTXA command can be used
to format one DASD at a time, but the CPFORMAT EXEC is a wrapper around CPFMTXA that allows
the formatting of multiple DASD.
To have access to enough DASD to define four more user IDs, LINUX01 - LINUX04, with two
3390-3 volumes each, eight 3390-3s will be needed. In the examples used in this book,
3390-9s are being used, and two thirds of the volume 63A9 is available. So only two more
volumes are needed: 63AA and 63AB. Consult your worksheets on 2.7.2, “z/VM DASD
worksheet” on page 17 to determine how many volumes you will need for four new virtual
machines.
To format DASD for minidisks, perform the following steps:
► Logon to a 3270 session as MAINT.
► Query the devices that will be used for the remaining Linux user IDs.
