High Availability (HA) configuration overview

You can configure system controller high availability (HA) from Controller Management screen on the system controller webUI. The system controllers work together as a redundant pair. The default mode for system controller HA is Auto, which automatically selects the system controller that is best suited at the time as the active controller and fails over only as needed.
The High Availability screen on the chassis partition webUI includes options for configuring chassis partition HA. High availability is already implemented for chassis partitions on the VELOS system.

Configure high availability for the system controllers from the webUI

You should not need to change system controller high availability (HA) to something other than the default configuration (Auto), but you can opt to change the configuration or initiate a failover from the active controller to the standby from the system controller webUI.
  1. Log in to the VELOS system controller webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    Controller Management
    .
  3. For the
    Preferred Node
    field, select
    System Controller 1
    or
    System Controller 2
    to act as an active system controller, or choose
    Auto
    (recommended).
    Changing the Preferred Node configuration creates a failover event and ends the session if you select the system controller that is currently acting as the standby. Wait 30 seconds and then start a new session with either the floating IP address or the active system controller IP address after the change has completed.
    Hardware health conditions of the system controllers always take precedence. If one of the system controllers is not healthy, the chassis partition will ignore the preference and synchronize with the healthy system controller.
  4. To force a failover to occur immediately, click
    Failover
    .
    The
    Failover
    button is available only when
    Preferred Node
    field is set to
    Auto
    .
    You would do this only if you want the current standby system controller to become the active system controller.

Configure high availability settings for chassis partitions from the webUI

You should not need to change chassis partition to something other than the default configuration (Auto), but you can opt to change it or initiate a failover from the active chassis partition to the standby from the chassis partition webUI.
  1. Log in to the VELOS chassis partition webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    High Availability
    .
  3. For
    Preferred Node
    , select the system controller to run the active instance of the chassis partition, or choose
    Auto
    to let the system decide.
    Using
    Auto
    is strongly recommended.
    Hardware health conditions of the system controllers always take precedence. If one of the system controllers is not healthy, the chassis partition will ignore the preference and synchronize with the healthy system controller.
    If you select a preferred node other than auto, the preference is ignored unless you enable
    Auto Failback
    .
  4. If you really want to indicate a preference and have selected one of the system controllers (not auto):
    1. Set
      Auto Failback
      to
      Enabled
      .
    2. In the
      Failback Delay
      field, type the number of seconds to delay before initiating the failback.
  5. To force a failover to occur immediately, for
    Force Failover
    , click
    Failover
    .
    You would only do this only if you want the current standby system controller to become the active system controller.

System inventory overview

The System Inventory screen on the system controller webUI enables you to see an inventory of all components on the VELOS system, including the system controllers, blades, power supply units (PSU), PSU controller, fan tray, and LCD. The inventory includes the component name, status, part number, and serial number.

Log and report configuration overview

The system controller and chassis partition webUIs include options for configuring remote log servers and the log severity level for individual software components and services.
Both webUIs also enable you to generate a system report, or QKView file, to collect configuration and diagnostic information from the VELOS system if you have any concerns about your system operation. The QKView file contains machine-readable (JSON) diagnostic data and combines the data into a single compressed tar.gz format file. You can upload the QKView file to F5 iHealth where you can get help to verify proper operation of the system and get help with troubleshooting and understanding any issues you might be having and ensure that the system is operating at its maximum efficiency.

Configure log settings from the webUI

You can add and display information about configured remote log servers from either the system controller or chassis partition webUIs. You can also change the log severity level for individual software components and services.
  1. Log in to the VELOS system controller webUI or the chassis partition webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS

    is the default so all except debug-level events are logged.
  11. To delete a remote log server, select the server and click
    Delete
    .

Generate system reports (QKView) from the webUI

If you want to upload the report to the F5 iHealth server, your VELOS system must have DNS configured and have Internet access to these services using the HTTPS/443 remote service/port:
  • api.f5.com
  • ihealth-api.f5.com
You can generate a system controller QKView from either the system controller or chassis partition webUI. Both reports contain diagnostic information, such as configuration data, log files, time series statistics, and platform information.
  1. Log in to the VELOS system controller webUI or the chassis partition webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    System Reports
    .
    The System Reports screen displays. A list of QKView reports that were previously generated are shown with any reports that were uploaded to iHealth.
  3. To generate a system report, click
    Generate QKView
    in the upper right corner of the screen.
    The Generate QKView box displays these additional options:
    Option
    Description
    Filename
    Specify a name for the file to which QKView data is written. The default filename is <
    system-name
    >.qkview.
    Timeout Value
    Specify the time in seconds after which to stop QKView collection. The default value is 0, which indicates no timeout.
    Max File Size
    Exclude all files greater than the specified size (in MB). The range is from 2 MB to 1000 MB. The default value is 500 MB.
    Max Core Size
    Exclude core files greater than this size (in MB). The range is from 2 MB to 1000 MB. The default value for maximum core size is 25 MB.
    Exclude Cores
    Specify whether core files should be excluded from QKView. The default is to include core files.
    The system runs many commands to collect the diagnostic information, so generating the report might affect its performance.
    It takes a few minutes for the system to finish creating the report and list it on the screen. The QKView Status changes to
    File generated successfully
    when it is done.
  4. To upload the report to the F5 iHealth server, select the check box next to the QKView name and click
    Upload to iHealth
    .
    The QKView tar file uploads to iHealth, where you can get help to diagnose the health and proper operation of the system.
  5. To delete a QKView report, select it and click
    Delete
    .

File utilities overview

    local-file-path
    >

Certificate management overview

Before
VELOS
systems can exchange data with one another, they need to exchange device certificates, that is, digital certificates and keys used for secure communication.
If you are using LDAP with transport layer security (TLS) for user authentication, you can choose to require TLS Certificate Validation in the authentication settings. You can add a certificate and key into the system, and when you create a certificate signing request (CSR), it saves the generated key and certificate to these directories:
  • system/aaa/tls/config/key
  • system/aaa/tls/config/certificate

View or replace TLS device certificates from the webUI

Before you can install device certificates, you must enable LDAP as an authentication method in the system controller or chassis partition in which you are working (
USER MANAGEMENT
Auth Settings
).
You can view or replace TLS device certificates from either the system controller or chassis partition webUI. The device certificates apply only to the area in which you are working.
  1. Log in to the VELOS system controller webUI or the chassis partition webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    Certificate Management
    .
  3. To display a
    TLS Certificate
    or
    TLS Key
    that was previously installed, click

  5. To install a
    TLS Key
    , paste the text of the local certificate for client TLS authentication.
  6. Click
    Save
    .

System licensing overview

You can activate a license for the
VELOS
system from either the system controller CLI or webUI. There is one license per
VELOS
system, which is used by the chassis partitions and any tenants.
There are two ways to license the system:
Automatically
If your system is connected to the Internet, use the Automatic method to prompt the system to contact the F5 license server and activate the license.
Manually
If your system is not connected to the Internet, use a management workstation that is connected to the Internet to retrieve an activation key from
F5
and then transfer it to the system.
Adding or reactivating a license on an active
VELOS
system might impact traffic on tenants
running on chassis partitions
. Traffic processing will stop briefly on the tenants, and then restart automatically. This occurs when the tenant receives a new or reactivated license causing a configuration reload on the tenants. For more information, see these other references:

System licensing from the CLI

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 BIG-IP tenants.

License the system manually from the CLI

You can activate the VELOS system license manually 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. Get the system dossier.
    system licensing get-dossier [registration-key XXXXX-XXXXX-XXXXX-XXXXX-XXXXXXX]
    The registration key is optional. If it is not included, the system uses the one already pre-installed. If no registration key is found, you receive an error.
    The dossier for the system displays.
  5. Get the license file using the dossier output you just received by going to the F5 site license.f5net.com/license/dossier.jsp.
  6. Install the license.
    1. Copy the license file text.
    2. Run the manual install command and press Enter:
      system licensing manual-install license

Appliance mode overview

You can run the system in
appliance mode
. Appliance mode adds a layer of security removing user access to Root and Bash. Enabling appliance mode disables all Root and Bash shell access for the system.
You can enable appliance mode at each of these levels:
  • System
  • Tenant
Appliance mode is disabled at all levels, by default. You can enable it from the webUI or the CLI. The appliance mode option for the system is available to users with admin access under
SYSTEM SETTINGS
General
in the webUI. For tenants, it is available in the webUI under
TENANT MANAGEMENT
Tenant Deployments
.
These are the effects of enabling appliance mode at each of the different levels.
System-level appliance mode
  • Root or Bash access is disabled on the system.
  • Console access: Root or Bash access is disabled on the system. Users can log in to the system CLI from the console using an admin account.
Tenant appliance mode
  • Root access to the tenant is disabled by all means. Bash access is disabled for users (with a terminal shell flag enabled) inside the tenant.
  • Users can access the tenant only through the webUI or the CLI.
  • Tenant console access: Users can log in to the CLI from the virtual console using an admin account (with a terminal shell flag enabled).

Configure appliance mode from the webUI

You can enable appliance mode if you want to disable all root and Bash shell access.
For greater security, it is highly recommended that you configure the system controllers and chassis partitions to run in appliance mode.
From the system controller webUI, appliance mode disables root and Bash access to the controllers. From the chassis partition webUI, appliance mode limits access to the specific partition you are logged in to. You can enable or disable the appliance mode for system controllers and partitions from their respective webUIs.
The appliance mode option for tenants is available in the chassis partition webUI under
TENANT MANAGEMENT
Tenant Deployments
.
  1. Log in to the VELOS system controller webUI or the chassis partition webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    General
    .
  3. For
    Appliance Mode
    , select
    Enabled
    to enable it, or
    Disabled
    to disable it (the default).
  4. Click
    Save
    .

Cluster details overview

A cluster on a VELOS system is group of blades or nodes working together as a logical unit. The Cluster Details screen on the chassis partition webUI provides detailed information about clusters that might be useful when a chassis partition is made up of more than one slot/blade.

    .

Configure the system date/time from the CLI

You can manually configure the date and time for your system from the 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. Change the system date and/or time.
    You can opt to change only the time or only the date by including only the relevant option (either
    time
    or
    date
    ).
    system set-datetime date <
    YYYY-MM-DD
    > time <
    HH:MM-SS
    >
    In this example, you change the system date to 2021-01-01 and the system time to be 12:01:00:
    syscon-1-active# system set-datetime date 2021-01-01 time 12:01:00
The system date/time is now updated.

Configure the hostname from the CLI

You can manually configure the hostname for your system from the CLI. The hostname must be fully qualified domain name (FQDN).
  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. Change the hostname.
    system config hostname <
    hostname
    >
    The minimum length is 1 character, and the maximum length is 253 characters.
    In this example, you change the hostname for the system to test.company.com:
    syscon-1-active# system config hostname test.company.com
The system hostname is now updated.

System reboot overview

If you are having an issue with a chassis partition (such as unusually high CPU or memory usage or lockup), it is possible that rebooting a blade in the chassis partition might help to resolve the issue.
When there is a problem, the system sends alerts that you would see on the dashboard or on the Alarms & Events screen. A blade status of
Not ready
for a prolonged time on the General screen can also indicate the need to reboot the blade. You should rarely have to reboot a blade, however, because typically if the VELOS system needs to reboot a blade, it will do so automatically without administrator intervention. F5 recommends working with customer support if you think a blade reboot is necessary.

Reboot a system controller from the CLI

You can manually reboot a system controller in your VELOS system 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. Reboot a system controller.
    system reboot controllers controller [
    active
    |
    standby
    ]
    In this example, you reboot the standby system controller:
    syscon-1-active# system reboot controllers controller standby
The specified system controller reboots.

Reboot a blade in a chassis partition from the CLI

You can manually reboot a blade in your system from the chassis partition CLI.
  1. Connect using SSH to the chassis partition management IP address.
  2. 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.
  3. Reboot a blade.
    cluster nodes node <
    blade-number
    > reboot
    In this example, you reboot blade-1:
    default-1#(config) cluster nodes node blade-1 reboot
The specified blade reboots.

Reboot a blade in a chassis partition from the webUI

You can reboot a blade within a chassis partition from the chassis partition webUI.
  1. Log in to the VELOS chassis partition webUI using an account with admin access.
  2. On the left, click
    SYSTEM SETTINGS
    General
    .
  3. Review the status of each of the blades in the chassis partition.
    The
    Reboot
    button will not be available for slots that do not have blades present, or for blades that are currently being rebooted.
  4. If you have tenants running on the chassis partition you might want to warn users that their service might be interrupted temporarily.
  5. If you decide that a reboot is necessary, click
    Reboot
    to the right of the slot containing the blade that you want to reboot.
    It takes a few minutes for the blade to reboot. The status will show
    Reboot in progress
    , then
    Not ready
    , and when reboot is complete, it says
    Ready
    .
