An ISO is an image file of the contents of a CD.
For example, by downloading the Red Hat Enterprise Linux ISOs to your system, you can then burn a CD that will be identical to the Red Hat Enterprise Linux CDs that are available in retail stores.
Red Hat Network (RHN) has the ISO images for Red Hat Enterprise Linux and has made them available for download. You can use these images as installation media by burning the ISO's as image files to CD-Rs. Please ensure that you burn the ISO images correctly. You can verify this by looking at the burned image. If you see multiple files and directories, then this should be correct. If you just see the filename.iso as the only file on the CD, then the CD will not boot and will need to be re-burned as an image file. Most CD burning applications will have "Burn as ISO" or "Burn as Image" as an option.
Select the channel you require from the Channel Name table. Note: You may have to select All from the Software Channels menu on the left to find the particular channel you desire. A channel would be a base channel, for example, Red Hat Enterprise Linux AS (v. 4 for 32-bit x86) or Red Hat Enterprise Linux AS (v. 4 for 64-bit AMD64/Intel EM64T).
Alternatively, Select Download Software from the Software Channels menu on the left, then choose the base channel.
To install Red Hat Enterprise Linux from a CD-ROM, choose the CD-ROM option and select OK. When prompted, insert the Red Hat Enterprise Linux CD into your CD-ROM drive (if you did not boot from the CD). Once the CD is in the CD-ROM drive, select OK, and press [Enter].
The installation program then probes your system and attempts to identify your CD-ROM drive. It starts by looking for an IDE (also known as an ATAPI) CD-ROM drive. If found, continue to the next stage of the installation process (refer to Section 2.10 Language Selection).
Note: To cancel the installation process at this time, iSeries users should vary off the NWS and pSeries users should press the computer's Reset button or use the [Control]-[Alt]-[Delete] key combination to restart your machine. You can safely cancel the installation at any point before the About to Install screen. Refer to Section 2.22 Preparing to Install in the manual for more information.
The following applies to pSeries systems only: If your CD-ROM drive is not detected, and it is a SCSI CD-ROM, the installation program prompts you to choose a SCSI driver. Choose the driver that most closely resembles your adapter. You may specify options for the driver if necessary; however, most drivers detect your SCSI adapter automatically.
Tip: A partial list of optional parameters for CD-ROM drives can be found in the Red Hat Enterprise Linux Reference Guide, in the General Parameters and Modules appendix.
First, make sure that you have downloaded the correct files. For each distribution there are binary files and source files. To complete an installation the four binary files for a particular distribution are required.
Simply burning these files to CD as files will result in a single file being burnt to CD with a .iso extension. If this occurs your disks will not be bootable. The files available from Red Hat Network (RHN) are disk images and need to be burned to CD as an image.
Your burning software will extract the files from the .iso and burn them to CD
See your specific burning software documentation for more information on how to burn images to CD.
To check if you have burned each image correctly simply examine the contents of the CD. Instead of a single .iso file the disk should contain multiple files and directories.
If you receive an error message stating No devices found to install Red Hat Enterprise Linux, there is probably a SCSI controller that is not being recognized by the installation program.
To remedy this problem, check your hardware vendor's website to determine if a driver diskette image is available that fixes your problem. Second, add dd to the IPL parameters line in the Network Storage Description. For more general information on driver diskettes, refer to the Installation Guide on Driver Media at http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/x8664-multi-install-guide/ap-driverdisk.html.
You can also refer to the Red Hat Hardware Compatibility List, available online at: http://hardware.redhat.com/hcl/
NFS installations can use ISO (or CD-ROM) images rather than copying an entire installation tree.
After placing the required ISO images (the binary Red Hat Enterprise Linux CD-ROMs) in a directory,
choose to install via NFS. You will then point the installation program at that directory to perform the
installation.
Verifying that the ISO images are intact before you attempt an installation will help to avoid problems
that are often encountered during an NFS installation. To verify the ISO images are intact prior to
performing an installation, use an md5sum program (many md5sum programs are available for various
operating systems). An md5sum program should be available on the same server as the ISO images.
Note: ISO images have an md5sum embedded in them. To test the checksum integrity of an ISO image, at the installation boot prompt, type:
linux mediacheck
Additionally, if a file called updates.img exists in the directory from which you install, then it will be used for installation program updates. Refer to the file install-methods.txt in the anaconda RPM package for detailed information on the various ways to install Red Hat Enterprise Linux, as well as how to apply the installation program updates.
Note: You can only have the ISO images for one release and one variant of Red Hat Enterprise Linux in the directory.
These instructions assume that you have already registered your system with Red Hat Network (RHN). If you haven't, please register your system before following these steps.)
There are a few ways to run the up2date command, each with slightly different uses and results. All of the command need to be run from ther terminal as the root user. If you're not the root user, then when you try to run the command, it will prompt you for your root password.
Use this command to bring up a graphical user interface (GUI)that will allow you to select which packages to install or update. From this GUI, you can also select to install or update packages that are on your "package skip list". The "package skip list" is a list of packages that up2date will not update or install unless the force option is used. By default, this includes all kernel packages.
This is run from the command line as root. If you aren't root and you try to run it, then the system will ask you for your root password. This will run the up2date program without popping up a GUI. It will go through and update all of the packages except for any packages on the package skip list.
This is run from the command line as root. If you aren't root and you try to run it, then the system will ask you for your root password. This will run the up2date program without popping up a GUI. It will go through and update all of the packages including any packages on the package skip list.
This is run from the command line as root. If you aren't root and you try to run it, then the system will ask you for your root password. Replace "packagename" with the name of the package (not including the version number).
This will then check to see if the package is installed on your system. If it is, it will check to see if the package needs any updates. If it does, then up2date will go and fetch the most recent update for the package and install it. The package doesn't need any updates, then up2date will return that the package is fully updated.
If the package doesn't exsist on the system, then up2date will install the most recent version.
**NOTE: to install or update a package that's on the package skip list, then you'll need to use this command instead: up2date -f packagename
The Red Hat Network Management and Provisioning subscriptions provide additional functionality to your Enterprise Linux subscription. The Red Hat Network Management or Provisioning subscriptions are not Red Hat Enterprise Linux subscriptions. To receive updates and support for Red Hat Enterprise Linux, you must first purchase a Red Hat Enterprise Linux subscription for the system you would like to connect to RHN. The Red Hat Enterprise Linux subscription includes access to the Red Hat Network for downloading updates, and varying levels of support services. Please contact customer service at 1-888-REDHAT-1 or customerservice@redhat.com to correct this issue.
Red Hat Network (RHN) can be configured to provide automatic updates to specific systems via the website. Once a system is configured to be automatically updated, it will download and install all relevant errata when it connects to RHN. The system will not install packages which are listed in that system's package skip list.
OR
/usr/sbin/rhn_register/usr/bin/up2date --registerCurrently, the contract numbers or order numbers are not tied to systems, but to the number of entitlements in the account.
The Red Hat Network account will support as many systems as the subscriber has active entitlements. If a contract is not renewed and an entitlement lapses, a system will be dropped from its base channel in Red Hat Network. This is done on a last-in first-out basis. In other words, the last system registered in Red Hat Network will lose its base entitlement first.
To renew a subscription please visit www.redhat.com/rhel/renew/ or contact the reseller from whom you purchased. If you would like to purchase a new Red Hat Enterprise linux subscription, please visit www.redhat.com/apps/commerce.
If you see the same system registered twice in your Red Hat Network account, please follow the instructions given below to remove it:
Duplicate system listings may be taking up available Update entitlements or base channels in your Red Hat Network account, preventing other machines from connecting successfully.
Each system requires one base channel to connect to the Red Hat Network. When a system is registered, it is assigned to the base channel that corresponds to the system's installed version of Red Hat Enterprise Linux. If the number of systems registered to the Red Hat Network exceeds the available subscriptions, the Red Hat Network would give you an error. If the subscription that you have purchased is different than what is installed on your system, you would also receive this error. To purchase additional Red Hat Enterprise Linux subscriptions please visit: https://www.redhat.com/apps/commerce/
It sounds like you have ran the registration process for up2date, but the system did not get associated with a channel to match the OS version. The most common cause of this is that you have run out of entitlements for that version of Red Hat Enterprise Linux. For example, you paid for 5 Red Hat Enterprise Linux 3 AS licenses and already have 5 Red Hat Enterprise Linux 3 AS systems registered within your Red Hat Network (RHN) account, and so attempting to register a 6th Red Hat Enterprise Linux AS 3 system will allow the registration of the system to your RHN account, but you cannot associate it with the correct channel.
To resolve this you will need to either free up an entitlement or purchase an additional entitlement. To free up an entitlement, login to your RHN account and delete a system. A possible system you can delete would be one that maybe you have registered more than once within your RHN account or a system which is no longer in production usage which you can delete. To delete a system, click onto it and then click on 'delete system' near the top right, then click the 'Delete Profile' button to confirm.
The other option is to contact your Sales Representative and purchase an additional license (entitlement) to associate with that new system.
Once you have a free entitlement, you can then associate that entitlement with the system which has no channel currently associated with it. To do this, within RHN click on the system in question, then click onto 'Channels' to see the channels associated for that system. Under 'Base Software Channel' choose from the drop down menu the correct channel for the system and click the 'Modify Base Channel' button to confirm the changes.
You should now find that the up2date program should run on that system and it functions as expected now that it has an entitlement and is associated with a base channel.
Most subscriptions for Red Hat Enterprise subscriptions do not require an activation code to access them. If you have received an email confirmation that your new service has been activated, you will only need your login and password to access the subscription. The email confirmation provides instructions for registration and where to download the ISOs for your subscription.
During registration, please do not enter a subscription number when you are prompted to, instead select the option "Use one of my existing subscriptions" or "I do not have a subscription number."
If you purchased a Red Hat Enterprise Linux subscription from one of our Value Added Resellers, a login or account number should have been included at the time of purchase. When the order has been fully processed, a confirmation email will be sent letting you know how to access the subscription(s) in the account that has been requested. The subscription(s) will be active from the time that the notification is sent for the full term of the subscription. If you have placed an order and received confirmation, but cannot locate the subscription in your account, please contact Red Hat Customer Service [http://www.redhat.com/about/contact/dir/#custservice] with the confirmation email on hand for reference.
If you have purchased a Red Hat Enterprise Linux subscription from one of our OEM resellers (ie Dell, IBM or HP) an activation code is included in your purchase. The code will need to be activated before the subscription can be accessed for support and updates. To activate the subscription, please visit â http://www.redhat.com/activate.
If you have questions regarding registering your system to Red Hat Network, please visit our Knowledgebase at kbase.redhat.com or the Help section in Red Hat Network at https://rhn.redhat.com/help/index.pxt.
To consolidate all subscriptions under one Red Hat Network login account, please send a formal subscription transfer request at customerservice@redhat.com.
The email must be sent from the email address registered to the account where the subscriptions are currently located. The request should also cc the email address registered to the account where you would like the subscriptions to be transferred. In your email, please also specify the Red Hat login names for the originating account, and the destination account.
Please note that all open web support tickets MUST be closed for the contracts that you wish to transfer. We will not be able to proceed until this has been completed. Web Support tickets are not transfered between accounts.
