IBM System Cluster 1350, Installation And Service

Page: 55 / 170

Installation of the operating system begins with the Management Node in the
Primary cabinet.
Installing Red Hat Linux 7.3 or 8
The following steps provide a general path through the installation process and
assume you will install Red Hat Linux 7.3 from the product CDs.
This process assumes you have successfully cabled together all devices within each
cabinet and that you have correctly cabled together all cabinets. The software
installation process begins with the Management Node in the Primary cabinet.
Make sure the Management Node and all the switches are powered up. Cluster
Nodes will be powered up later in the install process.
1. Power up the Management Node and press the F1 key. Make any necessary
changes to set the boot order as follows:
v
Floppy diskette
v
CD-ROM
v
Fixed disk
v
Network
2. Ensure that hard disk 1 and 2 in the Management Node are set up as a RAID
1 mirror.
To set up the disks as a RAID 1 mirror, reboot the Management Node and at
the LSI Logic prompt press the CNTRL + C keys. Highlight the first drive
listed with Boot Order 0 and then highlight Mirroring Properties. Set drive 0
to primary and drive 1 to secondary. Press ESC and then Enter and save your
configuration changes. Exit the configuration utility. You will get a message
that the drives are resynching.
3. Insert the Red Hat 7.3 Linux product CD and restart the Management Node.
4. When prompted about the installation method you want to use select
CD-ROM
.
5. When prompted to choose an installation type, select Custom.
You will use disk druid to manually partition the drive. First, delete all
partitions on sda. Unhighlight all the drives listed by disk druid except for
sda
and create the following partitions:
v
A /boot partition with a size of 50 MB.
v
A /csminstall partition with 2 GB for each distribution of Red Hat Linux
installed on the managed nodes.
v
A /opt partition of 2 GB.
v
A /var partition of 1 GB for each 128 nodes in the cluster. If there are fewer
than 128 nodes in the cluster you should still set aside 1 GB. If there are
more than 128 nodes you should increase the size of the partition to 2 GB
or greater.
v
A /home partition of 2 GB, as a minimum. The customer should customize
this to meet their expected needs.
v
swap defined as 2 GB.
v
A root partition mounted as / with an initial size of 4 GB. Make sure you
select the Fill to maximum allowable size check box.
6.
When prompted about installing a Boot loader, take the default selection and
install the GRUB Boot loader in the Master Boot Record (MBR).
