Add devices back to BIG-IQ after deleting them from a silo for LTM conflict resolution

Add a BIG-IP device after removing it from a silo

After you've analyzed LTM service conflicts for a BIG-IP device you've placed in a silo, and you've removed that device from the silo, you can add the device to BIG-IQ and discover all of its services so you can manage it.
This figure illustrates the work flow for using a silo to resolve conflicts triggered by importing a BIG-IP device. Re-importing the devices is the last step in this process.
Re-import BIG-IP devices
Re-import BIG-IP devices
  1. At the top of the screen, click
    Devices
    .
  2. On the left, click
    BIG-IP DEVICES
    .
  3. Click the
    Add Device(s)
     button.
  4. For the Discovery Type setting, select
    Add BIG-IP device(s) and discover and import services in one step
    .
  5. Click the
    Add Device(s)
     button.
  6. For
    IP Address
    , type the IPv4 or IPv6 address of the device.
  7. Click the
    +
     button to add another IP address.
  8. Type the user name and password for these devices.
  9. In the
    Port
     box, type the management port for this BIG-IP device.
    The port number must be between 4 and 65535. In many cases, it's the default port 443.
    Chrome and Safari browsers don't allow access to web applications running on port 65535. So if you use port 65535 as the management port, you won't be able to access the BIG-IP device's interface from BIG-IQ when using Chrome or Safari. You can still discover and manage BIG-IP devices that are using port 65535.
  10. For the Target Silo setting, leave
    Do Not Use a Silo
     selected.
  11. Select the check box next to each licensed service running on the device(s) you are adding.
  12. If you are collecting statistics, for
    Status
    select the
    Enabled
    check box and a zone from the
    Zone
     list.
    If you do not define a zone, this device sends its statistics to DCDs assigned to the default zone.
    Zones
    are names created to associate BIG-IP devices with one or more DCD systems to help segregate statistic traffic by network topology, load, availability, and so forth, for optimal statistics traffic routing.
  13. If this device is part of a DSC group, for the
    Cluster Display Name
     setting, specify how to handle it:
    • For an existing DSC group, select
      Use Existing
       from the list, and then select the name of the DSC group from the next list.
    • To create a new DSC group, select
      Create New
       from the list, and type a name in the field.
    For BIG-IQ to properly associate the devices in the same DSC group, the
    Cluster Display Name
     must be the same for all members in a group.
    There can be up to eight members in a DSC group.
    For BIG-IP devices with ASM services, you can only add five devices at a time. If the BIG-IP device(s) provisioned with ASM is part of a DSC cluster, that device must also be a member of a sync-only device group, and ASM synchronization must be enabled for the device group. Without these DSC group settings, deploying changes to the ASM device can cause the cluster to get out of sync. For more information see K12200102, or the ASM Implementations chapter

  14. If this device is part of a DSC group, for the

     setting, specify how to handle it:

Without these DSC group settings, deploying changes to the ASM device can cause the cluster to get out of sync. For more information see K12200102, or the ASM Implementations chapter
    Automatically Synchronizing Application Security Configurations
     on
    support.f5.com
    .
  15. If this device is configured in a DSC group or you are creating a new DSC group, for the
    Cluster Properties
    , specify how to handle it:
    • Initiate BIG-IP DSC sync when deploying configuration changes (Recommended)
      : Select this option if you want this device to automatically synchronize configuration changes with other members in the DSC.
    • Allow deployment when DSC configured devices have changes pending ( Not Recommended)
      : Select this option if you want to deploy changes to this device even if there are changes pending for devices in the DSC group.
      This option is not recommended, because it can lead to unpredictable results.
    • Ignore BIG-IP DSC sync when deploying configuration changes
      : Select this option if you want to manually synchronize configurations changes between members in the DSC group.
  16. Click the
    Save & Close
     button at the bottom of the screen.
  17. When you are ready to discover and import services for these devices, click the
    Discover and Import
     button at the bottom of the screen.
    The BIG-IQ system opens communication to the BIG-IP devices, and checks the BIG-IP device framework.
    The BIG-IQ system can properly manage a BIG-IP device only if the BIG-IP device is running a compatible version of the REST framework.
  18. If a framework upgrade is required, in the popup window, in the
    Root User Name
     and
    Root Password
     fields, type the root user name and password for the BIG-IP device, and click
    Continue
    .
You can now manage these BIG-IP devices.
