Loading Linux from
removable media or from an FTP server
Instead of a boot
loader, you can use SE functions to copy the Linux kernel image to your
LPAR memory.
After the Linux kernel is loaded, Linux is started using restart
PSW.
Before you begin
You need installation data that includes a
special file with installation information (with extension ins).
This file can be in different locations:
On a disk that is inserted in the CD-ROM or DVD drive of the system
where the HMC runs
In the file system of an FTP server that you can access through
FTP from your HMC system
The .ins file contains a mapping of the
location of installation data on the disk or FTP server and the memory
locations where the data is to be copied.
For SUSE Linux Enterprise
Server 12 SP4 this file is called suse.ins and
located in the root directory of the file system on the DVD 1.
Procedure
Perform these steps:
In the navigation pane of the HMC, expand Systems
Management and Servers and select
the mainframe system you want to work with. A table of LPARs is
displayed on the Images tab in the content
area.
Select the LPAR where you want to boot Linux.
In the Tasks area, expand Recovery and
click Load from Removable Media or Server (see Figure 1).
Specify the source of the code to be loaded.
For loading from a CD-ROM drive:
Select Hardware Management Console CD-ROM/DVD (see Figure 2).
Leave the File location field blank.
For
an initial installation from removable media at the HMC
Select Hardware Management Console CD / DVD and assign
for operating system use (see Figure 2).
Enter the path for the directory where the ins-file is
in the File location field. You can leave this
field blank if the ins-file is in the root directory of the
file system on the removable media.
The installation CD or DVD must hold a distribution that supports
an installation from the HMC.
For loading from an FTP server
Select the FTP Source radio button.
Enter the IP address or host name of the FTP server with the installation
code resides in the Host computer entry field.
Enter your user ID for the FTP server in the User ID entry
field.
Enter your password for the FTP server in the Password entry
field.
If required by your FTP server, enter your account information
in the Account entry field.
Enter the path for the directory where the suse.ins resides
in the file location entry field. You can leave this field blank if
the file is in the FTP server's root directory.
Click Continue to display
the Select Software to Install panel
(Figure 3).
Select suse.ins.
Click OK to start loading Linux.
Results
The kernel has started and the SUSE Linux Enterprise
Server 12 SP4 boot process continues.
