Prerequisites

Before you upgrade or install

Before you install or upgrade
F5OS
on your system:
  • Ensure that you complete or verify the listed prerequisites for installation/upgrade tasks.
  • Verify that your network settings are configured.
  • Back up your system controller, chassis partition, and tenant configurations.
  • Export your backups to a safe, off-unit location.
  • Upload system controller and chassis partition image files to each chassis before the scheduled maintenance window to minimize the time needed to upgrade.
  • Upload tenant image files to all tenants before the scheduled maintenance window to minimize the time needed to upgrade.
  • Check the health and availability of virtual servers and pool members to determine their status before the upgrade.

Prerequisites for installation/upgrade

This lists a high-level overview of tasks that you should complete before you install or upgrade the
F5OS
software on your
VELOS
system.
Task
Action
Configure the front-panel management port on the system.
For more information, see the platform guide for your
VELOS
platform at techdocs.f5.com.
Connect the system controller to a serial console server.
Use these default serial port settings:
  • Baud rate: 19200
  • Data bits: 8
  • Stop bits: 1
  • Parity: None
  • Flow control: None
Configure basic management settings.
For more information, see the
Network settings reference
section.
Verify that an rsync server is reachable from the system for import of installation images onto the system
controller
.
For more information, see the rsync documentation (rsync.samba.org).
Update/reactivate your system license, if needed, to ensure that you have a valid service check date.
For more information, see K7727: License activation may be required before a software upgrade for BIG-IP.
Additional information about BIG-IP Next licensing may be available on the
F5
Beta portal.
Get a USB flash drive (minimum 8GB); only needed if using the USB method for performing a clean installation.
Verify that the drive is fully seated and flush in the USB port.
For security purposes, the USB port on the system
controller
is disabled by default. You can use Always-On Management (AOM) to enable the front panel USB port. For more information about AOM, see the platform guide for your
VELOS
platform at techdocs.f5.com.

Network settings reference

Before you perform a software installation/upgrade, verify that you have configured network settings by logging in to the system from a management console using an admin account and running these commands on the CLI. When you log in to the system, you are in user mode. Before you can complete configuration tasks, you must first change to config mode by typing
config
. You can type a question mark (
?
) or press the Tab key to see possible command completions in the CLI.
Be sure to commit all changes.
Task
Configuration example

VELOS
system backups

Creating a backup of your
VELOS
system is highly recommended, as it helps ensure that your active configuration files are retained, and you can restore from a known, stable environment if your upgrade is unsuccessful.

Back up and export system controller configuration

Before you perform an upgrade, it is a good idea to save and export a backup of the system controller configuration from the system controller CLI.
  1. Log in to the command line interface (CLI) of the system controller using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  2. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  3. Create a backup of the system controller configuration.
    system database config-backup name <
    filename
    >
    In this example, you create a backup file of the system controller configuration named
    controller-backup1.xml
    :
    system database config-backup name controller-backup1.xml
    System controller configuration backup files are located in
    configs
    .
  4. Verify that the backup file was created successfully.
    file list path configs/
  5. Export the configuration backup file to a safe location, such as an HTTPS server.
    file export local-file configs/<
    filename
    > protocol [ https | scp | sftp ] remote-file /tmp/<
    filename
    >.xml remote-host <
    ip-address
    > username root
    In this example, you connect as the root user to IP address
    192.0.2.75
    and export a backup file named
    controller-backup1.xml
    to the
    /tmp
    directory:
    file export local-file configs/<
    filename
    > remote-file /tmp/controller-backup1.xml remote-host 192.0.2.75 username root
    The system requests the password for the remote root account.
    Value for 'password' (<string>): ******* result File transfer is initiated.(configs/backup1.xml)
  6. Check the status of the file transfer.
    file transfer-status
    When the file transfer completes, the
    Status
    displays
    Complete
    .
You now have a backup of the system configuration on the system controller that you can restore on the system if needed.

Back up and export chassis partition configuration

Before you perform an upgrade, it is a good idea to save and export a backup of the chassis partition configuration from the chassis partition CLI.
  1. Log in to the command line interface (CLI) of the chassis partition using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  2. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  3. Create a backup of the chassis partition configuration.
    system database config-backup name <
    filename
    >.xml
    In this example, you create a backup file of the chassis partition configuration named
    chassis-partition-backup1.xml
    :
    system database config-backup name chassis-partition-backup1.xml
    Chassis partition configuration backup files are located in
    configs/
    .
  4. Verify that the backup file was created successfully.
    file list path configs/
  5. Export the configuration backup file to a safe location, such as an HTTPS server.
    file export local-file configs/<
    filename
    >.xml protocol [ https | scp | sftp ] remote-file /tmp/<
    filename
    >.xml remote-host <
    ip-address
    > username <
    username
    >
    In this example, you connect as the root user to IP address
    192.0.2.75
    and export a backup file named
    chassis-partition-backup1.xml
    to the
    /tmp
    directory:
    file export local-file configs/chassis-partition-backup1.xml protocol scp remote-file /tmp/chassis-partition-backup1.xml remote-host 192.0.2.75 username root
    The system requests the password for the remote root account.
    Value for 'password' (<string>): ******* result File transfer is initiated.(configs/chassis-partition-backup1.xml)
  6. Check the status of the file transfer.
    file transfer-status
    When the file transfer completes, the
    Status
    displays
    Complete
    .
You now have a backup of the chassis partition configuration that you can restore on the system if needed.

Tenant configuration backups

Before you perform an upgrade, it is a good idea to save and export a backup of the tenant configuration using that tenant's backup mechanism.
Tenant
Summary
Additional References
BIG-IP
For
BIG-IP
tenants:
Create a backup for each running tenant:
tmsh save sys ucs <filename>
Move these backup files to a safe location off of the tenant:
  • /config/bigip.conf
  • /config/bigip_base.conf
  • /config/bigip_user.conf
    (optional)
If you perform a clean installation, the tenant will be formatted.
Consider naming the files to associate them with the appropriate tenants.

License the system automatically from the CLI

For automatic
VELOS
system licensing, the system needs to be able to connect to the F5 licensing server either through the internet or another means of networking. You need to have the Base Registration Key (five sets of characters separated by hyphens) provided by F5, and any add-on keys (two sets of 7 characters separated by a hyphen) that you have purchased. The Base Registration Key with associated add-on keys are pre-installed on a new
VELOS
system.
You can activate the
VELOS
system license automatically from the system controller CLI.
  1. Connect using SSH to the system controller floating management IP address.
  2. Log in to the command line interface (CLI) of the system controller using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  4. Apply a license to the chassis.
    system licensing install registration-key <
    key
    >
    The registration key is optional. If it is not included, the system uses the one that is already pre-installed. If no registration key is found, you receive an error.
    This example applies a specified base registration license to the system:
    syscon-1-active(config)# system licensing install registration-key I1234-12345-12345-12345-1234567 result License installed successfully.
  5. Apply any add-on keys.
    system licensing install add-on-keys <
    add-on-keys
    >
    This example enables the additional features associated with the three specified add-on-keys, along with the entitlements of the base registration key:
    syscon-1-active(config)# system licensing install add-on-keys [1234567-1234567 2345678-2345678 3456789-3456789] result License installed successfully.
The
VELOS
system is licensed. The license and any add-on keys apply to all partitions and tenants.
