18.20. Installation Complete

download PDF
Congratulations! Your Red Hat Enterprise Linux installation is now complete!
The installation program prompts you to prepare your system for reboot.
The installation program automatically reboots into the installed system.
Should the installation program not reboot, the installation program shows information from which device to do an IPL (boot). Accept the shutdown option and after shutdown, IPL from the DASD or SCSI LUN where the /boot partition for Red Hat Enterprise Linux has been installed.

18.20.1. IPL under z/VM

To IPL from a DASD, for example using the DASD device 200 on the 3270 console, issue the command:
#cp i 200
In DASD only environments where automatic partitioning (clearing data from all partitions) was used, the first activated DASD is where the /boot partition is typically located.
Using /boot on an FCP LUN, you must provide the WWPN and LUN for the FCP-attached device from which to IPL.
To IPL from an FCP-attached device:
  1. Provide FCP routing information to an FCP-attached device, for example, where 0x50050763050B073D is the WWPN, and 0x4020400100000000 is the FCP LUN:
    #cp set loaddev portname 50050763 050B073D lun 40204001 00000000
  2. IPL the FCP adapter, for example FC00:
    #cp ipl FC00


To disconnect from the 3270 terminal without stopping the Linux running in your virtual machine, use #cp disconnect instead of #cp logoff. When your virtual machine is re-connected using the usual logon procedure, it might be placed in CP console function mode (CP READ). If so, to resume execution on your virtual machine, enter the BEGIN command.

18.20.2. IPL on an LPAR

For LPAR-based installations, on the HMC, issue a load command to the LPAR, specifying the particular DASD, or the FCP adapter, WWPN, and FCP LUN where the /boot partition is located.

18.20.3. Continuing after Reboot (re-IPL)

Following the automatic reboot or the manual IPL of the installed Red Hat Enterprise Linux operating system, you can log on to the system through ssh. Note that the only place from which you can log in as root is from the 3270 terminal or from other terminal devices listed in /etc/securetty.
The first time you start your Red Hat Enterprise Linux system in a graphical environment, you can use Initial Setup to guide you through Red Hat Enterprise Linux configuration. Initial Setup lets you configure your environment at the beginning, so that you can get started using your Red Hat Enterprise Linux system quickly.
See Chapter 30, Initial Setup for information about the configuration process.
