This technical note documents the process of upgrading a 520/540 (D35) platform to the BIG-IP software version 9.4.1 using a CD mounted on an installation server. For information about installing the software, please see the instructions below.
The minimum system requirements for this release are:
The supported browsers for the BIG-IP Configuration utility are:
Note that we recommend that you leave the browser cache options at the default settings.
Important: Popup blockers and other browser add-ons or plug-ins might affect the usability of the Configuration utility. If you experience issues with navigation, we recommend that you disable these types of browser plug-ins and add-ons.
This technical note describes how to upgrade version 9.x software to version 9.4.1 on the 520/540 platform. The 520/540 platforms are not switch-based platforms. Some BIG-IP features and requirements are slightly different, or are not supported, on the 520/540 platforms. The following section describes these features.
When you install BIG-IP version 9.4.1 on a 520/540 platform, the interface 1.1 is converted to the management interface. The minimal configuration is two built-in interfaces, however, we recommend that you add network interface card (NIC) to bring to the total number of interfaces to at least three.
The minimum memory supported is 512MB. Most 520 platforms shipped with only 256MB of RAM. The recommended amount of RAM is 1GB. To avoid complications stemming from combining dissimilar brands of DIMMs, if you upgrade the memory on a unit, we recommend that you discard the old DIMMs and replace them with a single 512MB or 1024MB DIMM.
BIG-IP Link Controller and BIG-IP GTM/LTM combination installations require a minimum of 768MB of memory. However, the recommended amount of RAM is 1GB.
The front panel LED behavior is the same as version 9.x behavior. For more information, see SOL4263: How has the behavior of the front panel LEDs changed in BIG-IP version 9.x?.
The VGA and serial console behave as described after you install BIG-IP version 9.4.1.
For details about obtaining supported network interface cards, contact F5 Networks.
Some switch-based BIG-IP features are not supported on the 520/540 platforms. This section describes these features and their behavior.
The following add-in hardware cards are not supported in this release on the 520/540 platforms:
LACP and STP are not supported on the 520/540 platform. LACP switchboard failsafe is not active on these platforms. The HA Table displays the switchboard failsafe entry as disabled. LACP is enforced when the user attempts to set lacp_enable 'true' on a trunk.
STP is enforced by the global stp mode setting. The allowed modes are passthru and disabled. Note you can view and modify the other stp related parameters without affecting the system operation. These commands include the bigpipe stp commands, bigpipe stp instance commands, and bigpipe interface stp, bigpipe auto edge, and the link type commands.
Most of the bigipipe commands are supported fully by the 520/540 platform, with the following exceptions:
|daemon||Displays the bcm56xxd. Not functional.|
|db boot.netreboot||Cannot enable. Not functional.|
|ha table||Displays switchboard failsafe as disabled. Not functional.|
|interface [stp | auto edge | link type ]||Can be configured. Has no effect.|
|interface pause||Not supported|
|mirror||Port mirror not supported and gives an error when configured.|
|stp||Cannot set mode. Not functional.|
|stp instance||Can be configured. Not functional.|
|trunk||Cannot enable lacp.|
Quiet boot is supported. You can set this variable using the bigdb boot.quiet setting. The D35 Tyan 2515 motherboard does not support a CMOS setting for quiet boot, so user must use the BIOS setup utility to configure the BIOS quiet boot setting.
The bigpipe command netboot enable | disable is not supported on the 520/540 platform. You must use the front panel Netboot button.
You cannot configure port mirroring on the 520/540 platform.
You can use the command bigpipe baud rate to modify the current serial console (ttyS0), and the grub baud rate setting. This baud rate is maintained across reboots and power cycles. However, the Tyan 251x BIOS does not support a CMOS setting for baud rate. As a result, for the PXE installation, you must use the BIOS baud rate setting (default 19200) for the serial console.
The sensor support for chassis fan, chassis power supply, chassis temperature, and cpu status is not be supported.
If the BIG-IP system is currently running version 9.2.x or later, you can upgrade directly to version 9.4.1, using the following procedure.
Warning: A valid service contract is required to complete this installation.
Warning: You must reactivate the license on the BIG-IP system on which you intend to install before you begin the installation.
The process of installing the BIG-IP version 9.4.1 software requires completing the following steps:
The following sections describe how to perform these tasks.
Before you upgrade to this version of the software, you need to save your current configuration data. Backing up your configuration prevents loss of data if, for any reason, the upgrade is not successful.
Collect and archive the existing configuration files, by typing the following command. Note that to have the installer automatically load the configuration file during startup, you must name the file config.ucs and store it in the / partition.
bigpipe config save /config.ucs
Important: If you are upgrading a system that is using zone files with named, you must manually back up all necessary zone files and save them to a remote location. After the upgrade is complete, you can place them on the upgraded system. There is a new location on the version 9.x system for these files: /var/named/config/namedb.
Important: It is critical that you back up the archived configuration files to a secure remote location. In the event this process fails, you might need to use the remotely-stored file in order to restore your previous configuration data. For more information about UCS files, see Solution ID: SOL4423 Overview of UCS archives.
Before you begin the installation process, you may need to download the installation CD-ROM ISO image from http://downloads.f5.com. For details about downloading the ISO image, see SOL167: Downloading software from F5 Networks
Note: Before continuing, we recommend downloading the associated MD5 checksum file and performing the MD5 checksum operation to ensure that the file downloaded correctly. For more information about running the MD5 checksum, see Verifying the MD5 checksum of the installation file.
Before you perform a network boot from a CD, you must designate and configure a remote host to be a Pre-boot Execution Environment (PXE) server. This remote host must meet all the following criteria:
Note: You must connect the installation server to the same network to which the BIG-IP unit is connected.
Once you have designated a host, complete the following steps:
Select terminal type? [vt100]
Press Enter to use vt100 emulation, or type the name of the terminal emulator you are using.
Maintenance OS Options Serve Provide network installation services Install Install software onto hard disk Reboot Reboot to your current system Exit Exit to maintenance shell
Use existing DHCP server on subnet [no]?
IP network [10.1.10]?
IP address of server 10.1.10[n] ?
Lower range for clients 10.1.10.[n] ?
Upper range for clients 10.1.10.[n] ?
Note: When you enter the IP address of the server, you need to enter only the last octet. When completing the lower and upper ranges for the clients, enter the network number(s) where the clients are situated.
After you designate and configure a remote host to be a installation server, you are ready to perform the network boot from the console of the platform on which you wish to install the software.
Note: You must connect the installation server directly to the management port on the BIG-IP unit, or to the network to which the management interface is connected.
If the machine is powered down, power it up, and within the first ten seconds use a paperclip to push the NETboot button on the front panel of the IP Application Switch.
If the machine is started and running, type the following two commands in sequence:
bigpipe db boot.netreboot enable
rebootYou may receive the following message after you type the reboot command:
The requested operation is not supported by the hardware.If you see this error message, use a paperclip to push the RESET button on the front panel of the IP Application Switch. Then, within ten seconds, use a paperclip to push the NETboot button.
Press M or Control-SPACE to view menu.Let the timer count down to auto-select the installation options. After the timer counts down, the installer presents the terminal type.
Terminal type? [vt100]Press Enter to continue, or type the terminal type you are using. We recommend that you use vt100.
Note: The syslog option is not present when the controlling terminal is the console. You see this option only when you are performing the installation through an SSH connection.
The software takes only a few minutes to install. Once the installation is complete, the unit reboots to the installation in slot 0. You can use the switchboot utility to specify which installation you want to boot by default. For more information about the switchboot utility, see the BIG-IP version 9.4.1 release notes.
After you complete the installation of the software, and before you license the software, run the config command to configure an IP address, net mask, and gateway on the management port (MGMT). The config command is a command line utility created for this purpose. You can run the config command from the serial console you used during installation.
To run the config command, type the following command:
After you run this utility and add an IP address, net mask, and gateway to your management port, you can log in to the Configuration utility (graphical user interface), and license the unit.
Before you can convert your configuration files or configure the system, you must license the software. To activate the license for the system, you must have a base registration key. The registration key is a 27-character string that lets the license server know which F5 products you are entitled to license.
