This is a very basic description on installing Red hat 5.5 Enterprise Linux. There are a few notes that need to be shared:

During the installation booting and starting the installation you are requested to fill in the installation number (subscription number). To find it do the following:

• Login to your Customer Portal page at https://access.redhat.com
• Choose the 'Manage your Subscriptions' tab.
• You will see your installation number (subscription number) in the seventh column beside the corresponding subscription.

Make sure you list your subscription details in your password database.

As a user you can issue the command “system-config-lvm” which will start a graphical overview of LVM with the option to delete and create a LVM volume. It's not possible to recreate a LVM volume.

Afterwards you can check the settings and configuration of the LVM volume with the “dumpe2fs” command (as root):

[root@redhat ~]# dumpe2fs -h /dev/mapper/ApplVG-DatabaseLV
