► Verify that the new user IDs have access with the QUERY VSWITCH ACCESSLIST command: ==> query vswitch vsw1 acc VSWITCH SYSTEM VSW1 Type: VSWITCH Connected: 4 Maxconn: INFINITE PERSISTENT RESTRICTED NONROUTER Accounting: OFF VLAN Unaware State: Ready IPTimeout: 5 QueueStorage: 8 Portname: UNASSIGNED RDEV: 3004 Controller: DTCVSW1 VDEV: 3004 Portname: UNASSIGNED RDEV: 3008 Controller: DTCVSW2 VDEV: 3008 BACKUP Authorized userids: LINUX01 LINUX02 LINUX03 LINUX04 RH6CLONE RH6GOLD SYSTEM ... 9.5.4 Testing logging on to a new user ID You should now be able to logon to a new user ID and verify the integrity of the definitions. Perform the following steps ► Logon to LINUX02 and you should first notice that a NIC is created as well as two VDISKs: LOGON LINUX02 00: NIC 0600 is created; devices 0600-0602 defined z/VM Version 6 Release 1.0, Service Level 1002 (64-bit), built on IBM Virtualization Technology There is no logmsg data FILES: NO RDR, NO PRT, NO PUN LOGON AT 11:05:06 EDT TUESDAY 10/05/10 z/VM V6.1.0 2010-09-23 11:31 DMSACP723I A (191) R/O DMSACP723I C (592) R/O DIAG swap disk defined at virtual address 300 (64989 4K pages of swap space) DIAG swap disk defined at virtual address 301 (129981 4K pages of swap space) Do you want to IPL Linux from minidisk 100? y/n n If you forgot to grant access to the VSWITCH you will see an error message. ► Verify that you have two read/write devices at addresses 100-101 with the QUERY DASD command: ==> q da DASD 0100 3390 UM63AA R/W 3338 CYL ON DASD 63AA SUBCHANNEL = 0000 DASD 0101 3390 UM63AA R/W 3338 CYL ON DASD 63AA SUBCHANNEL = 0001 ... ► Logoff of LINUX02. Congratulations, you have cloned one Linux virtual server and defined three more user IDs that should now be ready for cloning to. You will clone to these user IDs in the chapter that follows. In addition to cloning, the Red Hat kickstart tool can also be used. That is discussed in Chapter 10, “Installing Linux with kickstart” on page 163. 9.6 Reviewing system status You can step back now and view your system from a DASD point of view as shown in Figure 9-2. If you have followed all sections in this book you should have used the equivalent 160 The Virtualization Cookbook for RHEL 6
of 23 3390-3 volumes: 8 for the z/VM system, 7 for the Linux cloner and golden image and 8 for the four virtual servers. You can also view the system from an administrator’s and end user point of view as shown by the horizontal lines and the italicized text on the right side of the figure. 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 end users may not care that their servers are virtual machines and may be oblivious to the fact that they might have been cloned in a matter of minutes.
