==> #cp vi vmsg 0 1 In single user mode, you are logged in as the root user. You can use the passwd command to set the root password. All of the file systems in /etc/fstab are mounted, but networking has not been started. To exit single user mode, you can type reboot, or enter init 3 to continue booting normally. 13.5.2 Entering a rescue environment If you encounter errors mounting the root file system, or have other problems that prevent you from entering single user mode, you can enter a rescue environment. This environment loads a Linux image in memory, and does not attempt to mount the root file system. To enter a rescue environment, initiate an interactive Linux installation. Perform the following steps to enter a rescue environment on the LINUX023 user ID: ► Logon to LNXMAINT. Copy the RHEL6 EXEC file to a new file named RESCUE EXEC, and copy the user’s PARM-RH6 file to a new file (LINUX02 RESCUE in this example): ==> copy rhel6 exec d rescue = = ==> copy linux02 parm-rh6 d = rescue = ► Edit RESCUE EXEC to point to the new RESCUE file: ==> x rescue exec /* EXEC to punch a RHEL 6 install system to reader and IPL from it */ Address 'COMMAND' 'CP SPOOL PUN *' 'CP CLOSE RDR' 'CP PURGE RDR ALL' 'PUNCH RHEL6 KERNEL * (NOHEADER' 'PUNCH' Userid() 'RESCUE * (NOHEADER' 'PUNCH RHEL6 INITRD * (NOHEADER' 'CP CHANGE RDR ALL KEEP' 'CP IPL 00C CLEAR' ► Edit the LINUX02 RESCUE file, replacing any kickstart or VNC lines with the rescue command line option: ==> x linux02 rescue d root=/dev/ram0 ro ip=off ramdisk_size=40000 CMSDASD=191 CMSCONFFILE=LINUX02.CONF-RH6 rescue ► Logoff of LNXMAINT ► Logon to LINUX02 and answer no to IPL from 100 question. ► Increase the memory to 1 GB: ==> def stor 1g 00: STORAGE = 1G 00: Storage cleared - system reset. ► uIPL CMS and again answer no to IPL from 100 question. ==> ipl cms 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 206 The Virtualization Cookbook for RHEL 6

E.g. using: ssh -x install@9.60.18.225 The install process directs you to telnet or SSH to the IP address of your Linux server to begin the first stage of the installation. ► Use SSH to connect to the IP address and log in as install. ► Choose your language ► The rescue environment will prompt you for the location of the rescue image, which is located in the install tree on the cloner.
