 += Notes, Tips & Tricks: Red Hat 5.5 =
  
 +This is a very basic description on installing Red hat 5.5 Enterprise Linux. There are a few notes that need to be shared:
 +
 +== Subscription / Installation Number ==
 +
 +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.
 +
 +== Recreate LVM Volume ==
 +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):
 +<​code>​
