Completing BIG-IQ Post Upgrade Processes

Add the standby BIG-IQ to the active BIG-IQ (manual failover configuration only)

After you upgrade your F5 BIG-IQ Centralized Management systems in an HA configuration, you can re-associate the standby BIG-IQ with the active BIG-IQ.
Add the standby BIG-IQ to the primary BIG-IQ to re-establish the manual failover high availability configuration.
  1. Log in to active BIG-IQ system with your administrator user name and password.
  2. At the top of the screen, click
    System
    .
  3. On the left, click
    BIG-IQ HA
    .
  4. Click the
    Add Standby
    button.
  5. In the
    IP Address
    field, type the discovery address you want to set up as the standby BIG-IQ.
    This is the same IP address the peers in a high availability configuration use to communicate.
    IPv6 short form addresses are not supported.
  6. Type the local administrative
    Username
    and
    Password
    for the system.
  7. Type the
    Root Password
    for the system.
  8. Click the
    Add
    button to add this device to this high availability configuration.
Even though you can log in to the standby BIG-IQ after the you re-establish the HA configuration, the system continues some database re-indexing processes in the background. For larger configurations, that can take up to an hour. If you perform any searches on objects before it's done re-indexing, BIG-IQ might not return the expected results.
After the HA configuration is re-established, you'll be automatically logged out of the active BIG-IQ for a few minutes while the standby BIG-IQ restarts.
After the standby BIG-IQ restarts, you can log back into the primary BIG-IQ.

Add a standby BIG-IQ to the active BIG-IQ (Auto Failover Configuration only)

Before you can add a standby BIG-IQ for an HA configuration with auto fail over, you must have a BIG-IQ system licensed and running, a second BIG-IQ system licensed, as well as a Data Device Cluster (DCD). If you don't have a DCD set up, you can do that during this procedure.
When configuring auto failover, you'll also create or select an existing Data Collection Device (DCD) as a quorum device. A
quorum DCD
is used as the deciding vote to determine which BIG-IQ becomes active if communication is disrupted between the active and standby BIG-IQ in the HA pair, by determining which BIG-IQ it can communicate with. The quorum DCD can be part of a DCD cluster, but is not used as a standby BIG-IQ in an HA configuration.
You set up BIG-IQ in an HA configuration so that if one BIG-IQ system goes offline, another BIG-IQ system can continue managing your devices without interruption. This procedure shows how to add a standby BIG-IQ configured for auto fail over.
  1. At the top of the screen, click
    System
    .
  2. On the left, click
    BIG-IQ HA
    .
  3. Click the
    Add Standby
    button.
  4. In the
    IP Address
    field, type the discovery address you want to set up as the standby BIG-IQ.
    This is the same IP address the peers in a high availability configuration use to communicate.
    IPv6 short form addresses are not supported.
  5. Type the local administrative
    Username
    and
    Password
    for the system.
  6. Type the
    Root Password
    for the system.
  7. For the
    Failover setting
    , select
    Auto Failover
    .
    For auto failover to work, you must have the following ports open on the active and standby BIG-IQ as well as the quorum DCD.
    • TCP port 2224
    • UDP port 5404
    • UDP port 5405
  8. For auto failover, you must associate a quorum DCD. If you do not have a DCD set up, click the
    Set Up Quorum Device
    button to specify the DCD you want to use. If you've already have a Quorum DCD for auto failover, select it from the list and type its
    Root Password
    .
    • If you do not have a DCD set up, click the
      Set Up Quorum Device
      button to specify the DCD you want to use.
    • you already have a Quorum DCD for auto failover, select it from the list and type its
      Root Password
      .
  9. If you want BIG-IQ to use a floating IP address when automatically failing over to the standby BIG-IQ, select the
    Enable Floating IP
    Enable
    check box and type the address.
    The floating IP address must be on the same network (this configuration uses Gratuitous ARP packets) as the active and standby BIG-IQ systems’ local management address (interface eth0) and not any of the discovery self IP addresses. This does not restrict HA traffic; HA traffic can be on any of the available interfaces. Floating IP addresses are not supported if your active and standby BIG-IQ systems are in a public cloud environment, such as AWS, Azure, or VMware.
    If you choose not to use a floating IP address and the active BIG-IQ fails over, you'll have to provide all users access to the newly active BIG-IQ by providing the IP address.
  10. Click the
    Add
    button to add this device to this high availability configuration.
The active BIG-IQ discovers the standby BIG-IQ and displays its status.

Refresh the database after a standby BIG-IQ is back online (Auto Failover Configuration only)

If the standby BIG-IQ in a high availability (HA) with auto failover configuration fails, is powered off, or if webd, restjavad, or postgres daemons are down, the active BIG-IQ the active BIG-IQ and continues to manage your BIG-IP devices.
When the standby BIG-IQ is back online, it automatically reestablishes its communication with the active BIG-IQ and the BIG-IQ DCD quorum. If the standby BIG-IQ was down for up to two hours, BIG-IQ displays
  1. At the top of the screen, click
    System
    .
  2. On the left, click
    BIG-IQ HA
    .
The active BIG-IQ discovers the standby BIG-IQ and displays its status.

What are my options for re-discovering and re-importing devices?

After you upgrade F5 BIG-IQ Centralized Management, you must re-discover and re-import services for your managed devices so you can start managing those devices with the new features introduced in this release. You can do this in bulk, or you do it for each device and service individually.
Regardless of which option you choose, you specify how to handle any conflict between objects in the BIG-IQ system's working configuration.
  • When you re-discover and re-import in bulk, all conflicts are resolved the in the same way.
  • When you re-discover devices and re-import services manually, you specify how to resolve conflicts on an individual basis.
Before you proceed to rediscover your devices, you need to update the BIG-IQ iApp to prevent BIG-IP CPU spikes. If your BIG-IQ or BIG-IP setups include one of the following conditions, and you have upgraded to a version earlier than 7.1.0, follow the procedure in the AskF5 article K53001642 on
support.f5.com
.

Re-discover and re-import services in bulk

After you upgrade F5 BIG-IQ Centralized Management, you must rediscover and re-import services for your managed devices so you can start managing those devices with the new features introduced in this release. Use this procedure to re-discover and re-import services in bulk. You'll have the option to decide how to manage any conflict between objects in the BIG-IQ system's working configuration and objects in the same way for each type of object.
  1. At the top of the screen, click
    Devices
    .
  2. On the left, click
  3. Select the check box next to the devices for which you want to rediscover and reimport services.
  4. Click the
    More
    button and select
    Re-discover and Re-import
    .
  5. In the
    Name
    field, type a name for this task.
  6. To create a snapshot of the BIG-IQ configuration before importing services, select the
    Snapshot
    check box.
    Clear this check box if you are adding devices that are in an access group you just created. If you don't, BIG-IQ won't be able to add the device(s).
  7. If BIG-IQ detects a conflict for services between the working configuration on BIG-IQ and the current configuration on BIG-IP, select a conflict resolution policy option for each object type.
    • Use BIG-IQ
      Keep the object settings in the BIG-IQ working configuration. The next time you deploy a configuration to that BIG-IP device, BIG-IQ overwrites the object settings to match the settings defined on BIG-IQ.
      Use BIG-IP
      Use the object settings from this BIG-IP device's configuration to replace the object in the BIG-IQ working configuration. The next time you deploy a configuration to your BIG-IP devices, BIG-IQ replaces that object settings for all of your managed BIG-IP devices to match the object settings on this BIG-IP device.
      Create Version
      For LTM monitors or profiles only, you can create and store a copy of the BIG-IP device's object(s), specific to the software version on that BIG-IP device. The next time you deploy a configuration, BIG-IQ replaces that object for all the managed BIG-IP devices running that specific version with the object on this BIG-IP. You can store multiple versions of LTM monitors or profiles. BIG-IQ deploys the appropriate stored version to your managed devices. BIG-IQ automatically resolves conflicts against the appropriate version the next time it imports services that contain LTM monitors or profiles.
After the services re-import, devices displays in the BIG-IP Devices inventory list with their services. You can now manage these BIG-IP devices from BIG-IQ.

Re-import and re-discover services

After you upgrade F5 BIG-IQ Centralized Management, you must re-discover and re-import services for your managed devices so you can start managing those devices with the new features introduced in the new release.
  1. At the top of the screen, click
    Devices
    .
  2. Select the check box next to the BIG-IP device you want to re-discover and re-import services for.
  3. Click the
    More
    button and select
    Re-discover and Re-import
    .
  4. Type a name for this task and then select the conflict resolution options you want to use if BIG-IQ finds differences between its working configuration and the configuration on the BIG-IP device.
    The BIG-IQ conflict resolution policy options are:
    Use BIG-IQ
    Keep the object settings specified in the BIG-IQ working configuration. The next time you deploy a configuration to that BIG-IP device, BIG-IQ overwrites the object settings to match the settings defined on BIG-IQ.
    Use BIG-IP
    Use the object settings specified in the BIG-IP device's configuration to replace the object settings in the BIG-IQ working configuration. For shared objects, the next time you deploy a configuration to a managed device, BIG-IQ replaces the settings for that object on the target device.
    Create Version
    For LTM monitors or profiles, you can create and store a copy of the BIG-IP device's object(s), specific to the software version on that BIG-IP device. For shared objects, the next time you deploy a configuration to a managed device, BIG-IQ replaces the settings for that object if that BIG-IP device is running that specific version. This option allows you to store multiple versions of LTM monitors or profiles knowing that BIG-IQ will deploy the appropriate stored version to your managed devices. The next time you import services that contain LTM monitors or profiles, BIG-IQ automatically resolves conflicts against the appropriate version.
  5. From the
    Available
    list, select the device you want to re-discover and re-import services for and move them to the
    Selected
    list.
  6. Click the
    Create
    button.
