NOTE: CentOS Enterprise Linux 5 is built from the Red Hat Enterprise Linux source code. Other than logo and name changes CentOS Enterprise Linux 5 is compatible with the equivalent Red Hat version. This document applies equally to both Red Hat and CentOS Enterprise Linux 5.

17.21. Installation Complete

Congratulations! Your Red Hat Enterprise Linux installation is now complete!

The installation program prompts you to prepare your system for reboot.

Once the installation is complete, you must IPL (boot) from either the DASD or SCSI LUN where /boot partition for Red Hat Enterprise Linux has been installed.

For example, using dasd at device 200 on the 3270 console you may issue the command #cp i 200. Often, especially in DASD only environments where automatic partitioning (clearing data from all partitions) was chosen, the first dasd (dasda) is where the /boot partition is located.

Using /boot on a SCSI LUN in a z/VM guest account, it may be necessary to provide WWPN and LUN information through which a zFCP device can ipl. As an example,

#CP SET LOADDEV PORTNAME 50050763 FCCD9689 LUN 83030000 00000000

could be used to provide zFCP routing information to a zFCP device (where 0x50050763FCCD9689 is the example WWPN, and 8303 is the SCSI LUN). Then the zFCP device information can be queried and used to start the IPL:

#cp q v fcp

After querying this information the zFCP device (4322 in this example) could be ipl-ed with a command like:

#cp ipl 4322

For LPAR-based installations, the HMC console may be used to issue a load command to the LPAR, specifying the particular DASD or SCSI LUN and zFCP WWPN where the /boot partition is located.


For guest accounts using z/VM, assuming you want to disconnect from the 3270 console without halting the linux guest, use #cp disc instead of #cp logout or #cp log. This allows for the virtual system running Red Hat Enterprise Linux for IBM System z to continue even when not connected to the 3270 console.

Following IPLing the installed Red Hat Enterprise Linux OS, you may log on to the system via ssh. It is important to note that the only place you can log in as root is from the 3270 or from other devices as listed in /etc/securetty.

The first time you start your Red Hat Enterprise Linux system in a graphical environment, the Setup Agent may be manually started, which guides you through the Red Hat Enterprise Linux configuration. Using this tool, you can set your system time and date, install software, register your machine with Red Hat Network, and more. The Setup Agent lets you configure your environment at the beginning, so that you can get started using your Red Hat Enterprise Linux system quickly.

For more information on using the Setup Agent, refer to the chapter titled Getting Started in the Red Hat Enterprise Linux Step By Step Guide.
