Upgrade guide for Scientific Linux Fermi 5

This web page describes upgrading for any Scientific Linux Fermi 5.x distribution. Simply replace anyplace that says 5.x or 5x with the appropriate version number. So if you were upgrading Scientific Linux Fermi 52, then you would replace 5.x with 5.2, and 5x with 52 wherever you see it in this document.

Before You Start

Upgrading using the regular installer, is the only way to upgrade from Scientific Linux Fermi 3.0.x. or 4.x to Scientific Linux Fermi 5.x. If you are only upgrading from one SLF 5.x to a newer SLF 5.x, (such as 5.1 to 5.2) then this proceedure is overkill. This proceedure will work, but it would be quicker to use yum.

SL 5.x Pre-Upgrade Checklist

Upgrade Media - This is the same media as the install media

Network Setup

This is a must if you are doing a network upgrade. It is not needed if you are doing a CD or DVD upgrade.
After the upgrade, your machine will have the same network configuration that it had before the upgrade, but you need these network settings to be able to actually do the upgrade.

  • DHCP
    This is where a IP address and hostname get assigned to your machine for a limited time. Most laptops work this way, where you just plug in your computer and you automatically are on the network. If you will be using DHCP during the upgrade, you do not need to figure out your IP address, it will be detected and used automatically.
    NOTE: If your computer's network card is not registered with Networking, and you attempt to do a DHCP network upgrade at Fermilab, you will not be able to reach the distribution servers. You will get an error saying that it could not find the distribution and ask you where the distribution is.
    You MUST have your machine registered with networking to do a DHCP network upgrade onsite.
  • Static IP Address
    Using a static IP address is the prefered way to network desktop and server machines. You will need to get a IP address from the DataComm Group. This generally takes a day to get into the system.
    The MAC (hardware) address of the ethernet card is needed in order to get a IP address.
    • We are currently determining the easiest way to obtain the MAC address. When we do we will have those instructions here.
    DataComm will supply you with your IP address, along with other information. During the update you will need
    • The IP address (suppliedby DataComm).
    • The network Netmask (suppliedby DataComm with the IP address).
    • The network Default Gateway IP address (supplied by DataComm with the IP address).

Scientific Linux Fermi v5.x Upgrade Steps

Upgrade Instructions

  • Network Upgrade: Note that the very first part of the upgrade is done in text mode. This is because we simply cannot fit the graphical upgrade onto the initial boot image. Once you connect to the installation server it will try to startup the graphical upgrade. Until that point, here are a few things to note.
    Use the Tab/Alt-Tab keys to navigate between elements.
    The <space> key selects/deselects items.
  • CDROM Upgrade: The first cdrom is bootable if your BIOS is configured to boot from cd-roms.
  • Text Upgrade: For either network or cd-rom upgrade, type in 'http text' and then return at the very first step.

Click on Section Name for detailed instructions.
Sections marked with a ** have default screens inside their section.

Bootup Screen (Enter) or [http text](Enter)

Language Selection(Shouldn't see normally)(Network install only) [OK]

Keyboard(Shouldn't see normally)(Network install only) [OK]

Installation Method(Shouldn't see normally)(Network install only) Pick installation method then [OK]

Configure TCP/IP(Network install only)

  • Choose DHCP
  • or
  • Enter the IP address (from your Network Manager)
    Netmask (from your Network Manager)
    Default gateway (from your Network Manager)
    Primary nameserver (from your Network Manager)

HTTP, NFS, or FTP Setup(Shouldn't see normally) (Network install only)
You should point your machine to your network installation server.
Depending on your network installation server, the path may be different. You should check to make sure you put the correct path in.
We are using i386 as an example, depending on what you are installing, you can replace that with x86_64. But you must have gotten your installation media from the appropriate images area, because an i386 network install cd will not work with x86_64 install directory, or vice versa.

HTTP server name:
Scientific Linux 5x (Fermi) directory: /linux/slf5x/i386

NFS server name:
Scientific Linux 5x (Fermi) directory: /export/linux/slf5x/i386

NOTE: FTP Installs are *not* recommended for SLF5
FTP server name:
Scientific Linux 5x (Fermi) directory: /linux/slf5x/i386

At this point, the installation try's to startup the graphical installation, unless you are doing a text installation. If for some reason the installation is unable to startup the graphical mode, then it will run the installation in text mode. Although this is a rare occurance, it does happen from time to time.
At this point, you can also take out the network install cd if you wish, it is not used again.
