Chapter 9. Configuring RHEL 5.2 for cloning 145

If you forgot to grant access to the VSWITCH you will see an error message. Verify that you

have OSA devices at addresses 600-602:

==> q osa

00: OSA 0600 ON NIC 0600 UNIT 000 SUBCHANNEL = 0002

00: 0600 QDIO-ELIGIBLE QIOASSIST-ELIGIBLE

...

Verify that you have two read/write devices at addresses 100-101 using the QUERY DASD

command:

==> q da

00: DASD 0100 3390 LXAE23 R/W 3338 CYL ON DASD AE23 SUBCHANNEL = 0000

00: DASD 0101 3390 LXAE24 R/W 3338 CYL ON DASD AE24 SUBCHANNEL = 0001

00: DASD 0190 3390 LX8RES R/O 107 CYL ON DASD CF31 SUBCHANNEL = 0009

00: DASD 0191 3390 LX8027 R/O 300 CYL ON DASD 8027 SUBCHANNEL = 000C

...

Logoff from LINUX02.

At this point you have cloned one Linux virtual server and defined three more user IDs that

should now be ready for cloning or kickstarting to. You will clone to these user IDs in the

chapters that follow.

9.5 Reviewing system status

Now you can view your system from a DASD point of view, as shown in Figure 9-2 on

page 146. If you have implemented the instructions in all sections in this book, you should

have used 24 3390-3 volumes: 10 for your z/VM system; 7 for the Linux controller and golden

image; and one for each of the seven virtual servers.

You can also view the system from an administrator’s perspective and from a user’s

perspective, as shown by the horizontal lines and the italicized text on the right side of

Figure 9-2 on page 146. The z/VM and Linux system administration roles may be performed

by the same person, but these roles can also be done by different administrators. The Linux

users may not care or be aware that their servers are virtual machines which might have been

cloned in a matter of minutes.
