Overview: Upgrading BIG-IP active-active systems

A BIG-IP® system active-active pair for version 10.x includes two BIG-IP systems operating in active mode (Device A and Device B).
Important: In order to upgrade version 10.0.0 or 10.0.1 to the new version software, you must first upgrade to version 10.1.0 or 10.2.x, and then upgrade version 10.1.0 or 10.2.x to the new version software. Additionally, you can only upgrade version 10.1.0 or 10.2.x to version 12.x if you have not provisioned Global Traffic Manager™ (GTM™).
A version 10.x active-active pair

A version 10.x active-active pair

After preparing the devices for an upgrade to the new version software, you force Device B to offline mode, and then install the new version software onto Device B (the offline device).

Important: Once Device B reboots, if the BIG-IP system is configured to use a network hardware security module (HSM), you must reinstall network HSM client software on Device B before upgrading Device A, to ensure that traffic groups using the network HSM function properly.
A version 10.x active-offline pair

A version 10.x active-offline pair

When you finish the installation of the new version software onto Device B, it creates two traffic groups called traffic-group-1 and traffic-group-2. Each traffic group is in standby state on Device B, and Device A (the version 10.x device) is in active mode. You can then force Device A to offline mode, changing both the new version software traffic groups to active state on Device B. Note that the Unit ID that was used in version 10.x becomes obsolete in the new version software.

You then install the new version software onto Device A.
Important: Once Device A reboots, if the BIG-IP system is configured to use a network HSM, you must reinstall network HSM client software on Device A to ensure that traffic groups using the network HSM function properly.

When you complete upgrading both devices to the new version software, the BIG-IP system configuration includes traffic-group-1 and traffic-group-2 in active state on Device B, a traffic-group-1 and traffic-group-2 in standby state on Device A, and a device group that includes both devices.

Once each device is upgraded to the new version software, you can reconfigure the traffic groups to become active on the devices that you want by forcing the active traffic group on a device to standby state. When forcing the traffic group to standby state, you can target the device upon which you want that traffic group to run in active state. For example, you can force traffic-group-1 on Device B into standby state, and into active state on Device A. Additionally, if you use HA groups, you can create a unique HA group for each traffic group on each device.

An upgrade of BIG-IP active-active systems to the new version software involves the following tasks.

Task Description
Preparing Device A (active mode on the BIG-IP 1 system) and Device B (active mode on the BIG-IP 2 system) In preparing to upgrade the active-active BIG-IP systems to the new version software, you need to understand any specific configuration or functional changes from the previous version, and prepare the systems. You also download the new version of software from the AskF5 web site (www.askf5.com) and import the files onto each device.
Forcing Device B to offline mode When you complete preparing the Device B, you can force Device B to offline mode.
Upgrading Device B (the offline mode BIG-IP 2 system) Once Device B is in offline mode, you can upgrade the software on that device, and reboot Device B to the location of the new version software image. Device B completes rebooting with traffic-group1 and traffic-group-2 in standby state.
Important: Once Device B reboots, if the BIG-IP system is configured to use a network hardware security module (HSM), you must reinstall network HSM client software on Device B before upgrading Device A, to ensure that traffic groups using the network HSM function properly.
Forcing Device A to offline mode When Device B completes rebooting to the location of the new version software image, you can force Device A to offline mode, changing traffic-group-1 and traffic-group-2 on Device B to active state.
Upgrading Device A (the offline mode BIG-IP 1 system) Once Device A is in offline mode, you can upgrade the software on Device A. When Device A completes rebooting, traffic-group-1 and traffic-group-2 are in standby state on Device A.
Important: Once Device A reboots, if the BIG-IP system is configured to use a network HSM, you must reinstall network HSM client software on Device A to ensure that traffic groups using the network HSM function properly.
Changing states of traffic groups When you finish upgrading all of the devices, you can restore the configuration of active traffic groups on each device.
Verifying the upgrade Finally, you should verify that your active traffic groups on the BIG-IP systems are functioning properly.
Configuring HA groups When you finish upgrading a device, the HA group on the device (in version 11.5, and later) applies to a traffic group, as opposed to the device. You can create a unique HA group for each traffic group on each device, as necessary.
Configuring module-specific settings According to your understanding of the configuration and functional changes from the previous version, you can reconfigure any customized module settings.

DSC components

Device service clustering (DSC®) is based on a few key components.

Devices
A device is a physical or virtual BIG-IP® system, as well as a member of a local trust domain and a device group. Each device member has a set of unique identification properties that the BIG-IP system generates. For device groups configured for failover, it is important that the device with the smallest capacity has the capacity to process all traffic groups. This ensures application availability in the event that all but one device in the device group become unavailable for any reason.
Device groups
A device group is a collection of BIG-IP devices that trust each other and can synchronize, and sometimes fail over, their BIG-IP configuration data. A Sync-Failover device group contains devices that synchronize configuration data and support traffic groups for failover purposes when a device becomes unavailable. The BIG-IP system supports either homogeneous or heterogeneous hardware platforms within a device group.
Important: BIG-IP module provisioning must be equivalent on all devices within a device group. For example, module provisioning is equivalent when all device group members are provisioned to run BIG-IP® Local Traffic Manager™ (LTM®) and BIG-IP® Application Security Manager™ (ASM™) only. Maintaining equivalent module provisioning on all devices ensures that any device in the device group can process module-specific application traffic in the event of failover from another device.
Traffic groups
A traffic group is a collection of related configuration objects (such as a virtual IP address and a self IP address) that run on a BIG-IP device and process a particular type of application traffic. When a BIG-IP device becomes unavailable, a traffic group can float to another device in a device group to ensure that application traffic continues to be processed with little to no interruption in service.
Device trust and trust domains
Underlying the success of device groups and traffic groups is a feature known as device trust. Device trust establishes trust relationships between BIG-IP devices on the network, through mutual certificate-based authentication. A trust domain is a collection of BIG-IP devices that trust one another and is a prerequisite for creating a device group for config sync and failover operations. The trust domain is represented by a special system-generated and system-managed device group named device_trust_group, which is used to synchronize trust domain information across all devices.
Folders
Folders are containers for the configuration objects on a BIG-IP device. For every administrative partition on the BIG-IP system, there is a high-level folder. At the highest level of the folder hierarchy is a folder named root. The BIG-IP system uses folders to affect the level of granularity to which it synchronizes configuration data to other devices in the device group.

About traffic groups

Traffic groups are the core component of failover. A traffic group is a collection of related configuration objects, such as a floating self IP address, a floating virtual IP address, and a SNAT translation address, that run on a BIG-IP® device. Together, these objects process a particular type of application traffic on that device.

When a BIG-IP® device goes offline, a traffic group floats (that is, fails over) to another device in the device group to make sure that application traffic continues to be processed with minimal interruption in service.

A traffic group is first active on the device you created it on. If you want an active traffic group to be active on a different device than the one you created it on, you can force the traffic group to switch to a standby state. This causes the traffic group to fail over to (and become active on) another device in the device group. The device it fails over to depends on how you configured the traffic group when you created it.

Note: A Sync-Failover device group can support a maximum of 127 floating traffic groups.

Task summary

The upgrade process involves preparation of the two BIG-IP® devices (Device A and Device B) configured in an active-active implementation, followed by the installation and verification of the new version software on each device. When you upgrade each device, you perform several tasks. Completing these tasks results in a successful upgrade to the new version software on both BIG-IP devices, with an active traffic group configured properly on each device.
Important: In order to upgrade version 10.0.0 or 10.0.1 to the new version software, you must first upgrade to version 10.1.0 or 10.2.x, and then upgrade version 10.1.0 or 10.2.x to the new version software. Additionally, you can only upgrade version 10.1.0 or 10.2.x to version 12.x if you have not provisioned Global Traffic Manager™ (GTM™).

Preparing BIG-IP modules for an upgrade from version 10.x to the new version software

Before you upgrade the BIG-IP® system from version 10.x to the new version software, you might need to manually prepare settings or configurations for specific modules.

Access Policy Manager system preparation

Access Policy Manager® is not supported in an Active-Active configuration.

Supported high availability configuration for Access Policy Manager

Access Policy Manager is supported in an Active-Standby configuration with two BIG-IP® systems only.

Important: Access Policy Manager is not supported in an Active-Active configuration.

Application Security Manager system preparation

The BIG-IP® Application Security Manager™ (ASM™) system does not require specific preparation when upgrading from version 10.x to the new version software. No additional configuration is required after completing the upgrade to the new software version.

What to expect after upgrading a redundant system

If you update two redundant systems that are running as an active-standby pair with BIG-IP Application Security Manager (ASM) and BIG-IP® Local Traffic Manager™ (LTM®) provisioned, the system maintains the active-standby status and automatically creates a Sync-Failover device group and a traffic group containing both systems. The device group is enabled for BIG-IP ASM (because both systems have ASM provisioned).

You can manually push or pull the updates (including BIG-IP LTM and ASM configurations and policies) from one system to the other ( Device Management > Overview , click the name of a device, and choose Sync Device to Group or Sync Group to Device).

Global Traffic Manager system preparation and configuration

BIG-IP® Global Traffic Manager™ systems require specific preparation tasks and changes to upgrade from version 10.x to the new version software.

Preparation Activities

Before you upgrade Global Traffic Manager systems that are in a synchronization group, from any software version to the new version software, you must install the software on an inactive volume on each device using Live Install. After you upgrade each device, you then switch all devices to the new volume at the same time. This is required because devices in a synchronization group that includes the new version software device, cannot effectively probe each other.

Post-upgrade changes
Important: In BIG-IP version 12.0, BIG-IP Global Traffic Manager is renamed to BIG-IP DNS. After you upgrade, you will see the new name in the product and documentation.

The following feature or functionality changes occur after you complete the upgrade process to the new version software:

Feature or Functionality Description
Assigning a BIG-IP system to probe a server to gather health and performance data Assigning a single BIG-IP system to probe a server to gather health and performance data, in version 10.x, is replaced by a Prober pool in the new software version.

Link Controller system preparation

The BIG-IP® Link Controller™ (LC™) system does not require specific preparation when upgrading from version 10.x to the new version software. No additional configuration is required after completing the upgrade to the new version software.

Local Traffic Manager system preparation

The BIG-IP® Local Traffic Manager™ (LTM®) system does not require specific preparation when upgrading from version 10.x to the new version software. No additional configuration is required after completing the upgrade to the new version software.

MAC masquerade addresses for VLANs
Note: If you configured MAC Masquerade addresses for VLANs on the version 10.x devices, one of the addresses will be included automatically in the MAC Masquerade Address field for traffic-group-1 during the upgrade.
HTTP Class profiles
F5 Networks® replaced the HTTP Class profile in BIG-IP® version 11.4.0, and later, with the introduction of the Local Traffic Policies feature. During an upgrade to BIG-IP version 11.4.0, if your configuration contains an HTTP Class profile, the BIG-IP system attempts to migrate the HTTP Class profile to an equivalent local traffic policy. For additional support information regarding the change of HTTP Class profiles to Local Traffic Policies, refer to SOL14409 on www.askf5.com.

WebAccelerator module preparation and configuration

BIG-IP® WebAccelerator modules require specific preparation tasks and changes to upgrade from version 10.x to the new version software.

Preparation activities

Before you upgrade the BIG-IP® WebAccelerator™ modules from version 10.x to an Application Acceleration Manager new software version, you need to prepare the systems, based on your configuration. The following table summarizes the applicable tasks that you need to complete.

Feature or Functionality Preparation Task
Symmetric deployment You must reconfigure symmetric WebAccelerator modules as asymmetric systems before you upgrade them from version 10.x to the new version software.
Unpublished policies You must publish any policies that you want to migrate to the new software version. Only published policies are migrated into the new version software.
Signed policies Signed policies are not supported in the new version software. If you use signed policies, you must replace them with predefined or user-defined policies before upgrading.
Configuration files Upgrading from version 10.x to the new version software does not include custom changes to configuration files. After upgrading to the new version software, you need to manually restore any customizations made to your configuration files by using the Configuration utility or Traffic Management Shell (tmsh). The following list includes examples of configuration files that might have been customized:
  • /config/wa/globalfragment.xml.10.x.0; in the new software version, all objtype entries are provided in tmsh.
  • /config/wa/pvsystem.conf.10.x.0
  • /config/wa/pvsystem.dtd.10.x.0
  • /config/wa/transforms/common.zip.10.x.0; the new software version does not include transforms.
Debug Options X-PV-Info response headers in version 10.x are changed to X-WA-Info response headers in the new software version. The default setting for X-WA-Info Headers is None (disabled). To use X-WA-Info response headers, you will need to change this setting, and update any associated iRules® or scripts, accordingly.
Post-upgrade activities

When you complete upgrading to the new version software, you should consider the following feature or functionality changes that occur for the Application Acceleration Manager modules. Depending upon your configuration, you might need to perform these changes after you upgrade the systems.

Feature or Functionality Description
Web acceleration Web acceleration functionality requires configuration of the Web Acceleration profile.
Important: You must enable an Application Acceleration Manager module application in the Web Acceleration profile to enable the Application Acceleration Manager module.
Compression Compression functionality requires configuration of the HTTP Compression profile in the new version software.
Request logging Request logging does not migrate to the new version software. You must recreate the configuration after upgrading by using the Request Logging profile.
Policy logging Policy logging does not migrate to the new version software. You must recreate the configuration after upgrading by using the Request Logging profile.
URL normalization URL normalization is not supported in the new version software.
ESI functionality Edge Side Include (ESI) functionality in the Application Acceleration Manager module is not supported in the new version software, with the exception of ESI invalidations.
iControl® backward compatibility Backward compatibility for iControl Compression and RAM Cache API settings in the HTTP profile is not supported in the new version software. These settings appear in the HTTP Compression and Web Acceleration profiles in the new software version.

WAN Optimization Manager preparation

BIG-IP® WAN Optimization Manager™ (WOM®) systems do not require specific preparation when upgrading from version 10.x to the new version software. However, in a redundant system configuration, you must upgrade the standby system first (to avoid interrupting traffic on the active system), and then upgrade the other system. No additional configuration is required after completing the upgrade to the new version software.

Preparing RAID drives for an upgrade

If your configuration includes redundant array of independent disks (RAID) drives, you need to verify that the RAID drives are ready for upgrading. If a RAID drive shows errors before upgrading, you will want to contact F5 customer support to resolve the errors before initiating the upgrade.
  1. Open the Traffic Management Shell (tmsh).
    tmsh
    This starts tmsh in interactive shell mode and displays the tmsh prompt: (tmos)#.
  2. Verify the health of RAID disks, ensuring that the drives are not failed or undefined.
    (tmos)# show sys raid
    Sys::Raid::Array: MD1
    --------------------
    Size (MB) 305245
    
    Sys::Raid::ArrayMembers
    Bay ID Serial Number Name Array Member Array Status
    ---------------------------------------------------------
    1 WD-WCAT18586780 HD2 yes failed
    2 WD-WCAT1E733419 HD1 yes ok

    In this example, the array is labeled MD1 and disk HD2 indicates an error.

  3. Verify Current_Pending_Sector data displays a RAW_VALUE entry of less than 1 on RAID systems.
    Option Description
    For version 11.4.0, and later Run the platform check utility: (tmos)# run util platform_check
    For version 11.3.x, and earlier At the command line, run the smartctl utility: smartctl -t long -d ata /dev/<sda|sdb|hda|hdc>
    197 Current_Pending_Sector  0x0032  200  200  000  Old_age  Always  -  0
    In this example, the RAW_VALUE entry is 0.
  4. Verify that no known issues appear in the following log files.
    • Check /var/log/user.log for LBA messages indicating failure to recover, for example, recovery of LBA:226300793 not complete.
    • Check /var/log/kern.log for ATA error entries.
The health of all RAID drives is assessed, enabling you to resolve any issues before proceeding with the BIG-IP® software upgrade.

Preparing BIG-IP active-active systems for an upgrade

The following prerequisites apply when you upgrade BIG-IP® active-active devices from version 10.x to the new version software.
  • The BIG-IP systems (Device A and Device B) are configured as an active-active pair.
  • Each BIG-IP device is running the same version of 10.x software.
  • The BIG-IP active-active devices are the same model of hardware.
When you upgrade a BIG-IP active-active pair from version 10.x to the new version software, you begin by preparing the devices.
Note: If you prefer to closely observe the upgrade of each device, you can optionally connect to the serial console port of the device that you are upgrading.
  1. For each device, complete the following steps to prepare the configuration and settings.
    1. Examine the Release Notes for specific configuration requirements, and reconfigure the systems, as necessary.
      For example, you must reconfigure version 10.x symmetric WebAccelerator modules as asymmetric systems before upgrading to the new version software.
    2. Examine the Release Notes for specific changes to settings that occur when upgrading from version 10.x to the new version software, and complete any in-process settings.
      For example, you must publish any unpublished BIG-IP® WebAccelerator™ module policies in order for them to migrate to the new version software.
  2. From the device that is running the latest configuration, synchronize the configuration to the peer unit.

Changing states of the traffic groups

Manually configuring active state traffic groups across devices within a device group involves forcing an active state traffic group on a device to standby state, and retargeting that active state traffic group to a different device. Completing these tasks results in active state traffic groups on the appropriate devices in a device group.

Viewing a list of traffic groups for a device

You can view a list of traffic groups for the device group. Using this list, you can add floating IP addresses to a traffic group, force a traffic group into a Standby state, and view information such as the current and next-active devices for a traffic group and its HA load factor.
  1. On the Main tab, click Device Management > Traffic Groups .
  2. In the Name column, view the names of the traffic groups on the local device.

Forcing a traffic group to a standby state

You perform this task when you want the selected traffic group on the local device to fail over to another device (that is, switch to a Standby state). Users typically perform this task when no automated method is configured for a traffic group, such as auto-failback or an HA group. By forcing the traffic group into a Standby state, the traffic group becomes active on another device in the device group. For device groups with more than two members, you can choose the specific device to which the traffic group fails over.

  1. Log in to the device on which the traffic group is currently active.
  2. On the Main tab, click Device Management > Traffic Groups .
  3. In the Name column, locate the name of the traffic group that you want to run on the peer device.
  4. Select the check box to the left of the traffic group name.
    If the check box is unavailable, the traffic group is not active on the device to which you are currently logged in. Perform this task on the device on which the traffic group is active.
  5. Click Force to Standby.
    This displays target device options.
  6. Choose one of these actions:
    • If the device group has two members only, click Force to Standby. This displays the list of traffic groups for the device group and causes the local device to appear in the Next Active Device column.
    • If the device group has more than two members, then from the Target Device list, select a value and click Force to Standby.
The selected traffic group is now in a standby state on the local device and active on another device in the device group.

Verifying a BIG-IP system active-active upgrade

Prerequisite: You must complete a software upgrade of the BIG-IP® active-active pair from version 10.x to the new version software.
When you have completed upgrading the BIG-IP active-active pair from version 10.x to the new version software, you should verify that the upgraded configuration is working properly. Perform the following steps to verify the new version software upgrade.
  1. Verify the Platform configuration for each device.
    1. On the Main menu, click System > Platform .
    2. For the Root Folder Device Group setting, verify that the device group is identical on the pair of devices.
    3. From the Root Folder Group list, verify that the correct traffic group (traffic-group-1) is selected.
  2. Verify the configuration for each device.
    1. On the Main menu, click Device Management > Devices .
    2. Verify the following information for the device and the peer device.
      • active-active status
      • device name
      • management IP address
      • hostname
      • TMOS version
    3. On the Main menu, click Device Management > Device Trust > Peer List .
    4. Verify that the peer device is specified as a Peer Authority Device.
      Note: Ensure that all information for the peer device appears correctly and complete.
  3. Verify the traffic groups for each device.
    1. On the Main menu, click Device Management > Traffic Groups .
    2. Click traffic-group-1.
    3. If you configured MAC Masquerade addresses for VLANs on the version 10.x devices, verify that the traffic-group-1 includes an address in the MAC Masquerade Address field.
    4. Click traffic-group-2.
    5. If you configured MAC Masquerade addresses for VLANs on the version 10.x devices, verify that the traffic-group-2 includes an address in the MAC Masquerade Address field.
    6. Verify that the floating traffic group is correct.
    7. Verify that the failover objects are correct.
  4. Verify the Current ConfigSync State for each device.
    1. On the Main menu, click Device Management > Overview .
    2. In the Devices area of the screen, in the Sync Status column, verify that each device shows a sync status of green.
The upgraded system is verified and working properly.

Implementation result

Your upgrade of the BIG-IP® active-active pair from version 10.x to the new version software is now complete. The new version software configuration includes a device group with two devices (Device A and Device B) and two traffic groups (traffic-group-1 and traffic-group-2), with the first traffic group (traffic-group-1) on one device (Device A) in active state and the second traffic group (traffic-group-2) on the other device (Device B) in active state.
