17.20. Installing Packages
At this point there is nothing left for you to do until all the packages have been installed. How quickly
this happens depends on the number of packages you have selected and your computer's speed.
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 the
/
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.
Note
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.
