9.5 Main installation steps

A SuSE license was first displayed in the newly opened X window:

click Accept

select English(US) and click Accept

The next steps involved DASD setup. Please read the text before attempting to follow our

examples.

Figure 9-1 DASD Module Parameter Setting

DASD initialization

STOP and read this section about DASD initialization before you do anything. If this is done

incorrectly, you may need to start the complete installation again.

YaST presented the DASD Module Parameter Setting panel, as shown in Figure 9-1. We

entered

dasd=200 in the DASD parameter box and clicked Load Module. Do not click Accept

yet.

We opened a new terminal window on the Red Hat gnome desktop and created a telnet

connection to SuSE (at IP address 192.168.0.112):

$ telnet 192.168.0.112

t23 login: root (Log in as root)

Password: root1 (Use the temporary root password we selected)

# cat /proc/dasd/devices (We should see device 200)

0200(ECKD) at (94: 0) is dasda .......

# dasdfmt -b 4096 -f /dev/dasda (Format the drive)

Type “yes” to continue, no will leave the disk untouched: yes

Formatting may take a while; ours took about 10 minutes.

We then used fdasd to partition

the drive into a large partition (for root) and a small swap partition. You might notice that fdasd

is a close relative of fdisk:

# fdasd /dev/dasda

n (Add a partition)

2 - 45000 (Tracks for the large partition)

n (Add another partition)

68

We had problems when we tried to repeat the dasdfmt step during a later installation. The dasdfmt program was

unable to write the IPL record and the target disk was unusable. We found it necessary to stop FLEX-ES, reformat

the volume (with the FLEX-ES ckdfmt program), and go through the whole SuSE initialization again before we could

run dasdfmt again. We suggest that you do not try to dasdfmt a volume a second time. You can repartition it with

fdasd without using dasdfmt again.

Chapter 9. Installing Linux for S/390 139

45001 - 50084 (Tracks for the small partition)

t (Change partition type)

2 (Type 2 is Linux swap)

p (Display partitions)

w (Write partition table and exit)

# exit (Exit from telnet session; close window)

After completing the fdisk step, we exited from the telnet window. We clicked Accept on the

YaST DASD Module Parameter Setting panel. The partition size we used for swap, about

5000 tracks, was quite arbitrary. It is approximately 240 MB and seemed a reasonable size.

On the next YaST panel, we clicked New Installation and OK.

On the main YaST panel, we clicked on the word Partitioning that is just above a red

message in the center of the panel. This started the Expert Partitioner with the panel shown

in Figure 9-2. In this panel:

Select /dev/dasda1 and click edit.

In the edit panel select Format, File System Ext3, Mount Point /, and click OK.

Select /dev/dasda2 and click edit.

In the edit panel select Format, swap, and click OK.

Click Next on the Expert Partitioner panel.

This exited from the Expert Partitioner.
