3. At the top of the screen, click Inventory.
4. On the left, click BIG-IQ HA.
5. Select the check box next to the secondary BIG-IQ, and click the Remove Device button.
   A dialog box opens, prompting you to confirm that you want to remove the peer device from this group.
6. Click Delete in the dialog box to confirm the removal.
   The system logs you out of the BIG-IQ while it removes the secondary device
7. Log back in to the primary BIG-IQ with your admin user name and password.
   For a while, both the primary and the secondary BIG-IQ devices continue to display. After a few minutes, the screen updates to display a single standalone device.

1. At the top of the screen, click System Management.
2. At the top of the screen, click Inventory.
3. On the left, click THIS DEVICE > SOFTWARE MANAGEMENT > Available Images .
4. Click the Upload Image button.
5. Click the Choose File button and go to the location to which you downloaded the image, and click the Open button to upload it to BIG-IQ.
6. Click the Upload button.
   The screen refreshes to display the progress of the upload.

1. Log on to the system you are going to establish as the secondary BIG-IQ system's command line as root and type the following command: /usr/bin/clear-rest-storage.
   Although this step is not required, it clears the database storage on the system so the upgrade goes more quickly. After you upgrade both peer systems and re-establish the HA pair, the peer BIG-IQ will synchronize its database with this BIG-IQ system and repopulate the database.
2. Log on to the system you are going to establish as the secondary BIG-IQ system's user interface.
3. If you ran the clear-rest-storage command, complete the setup wizard. Otherwise, continue to the next step.
4. At the top of the screen, click System Management.
5. On the left, click BIG-IQ DEVICES > BIG-IQ HA .
6. On the left, click Software Version.
7. Click the Update button.
8. From the Software Image list, select the image you want to install.
9. From the Target Volume list, select the volume you want to install the image on.
   Note: If the Target Volume list is empty, the machine you are upgrading does not have a second volume available for you to install the upgrade. You must create one to proceed.
   • If you selected a target volume, complete the remaining steps to finish the upgrade.
   • If you do not have a second volume, use the following procedure to install the upgrade for this machine:
     • Use SSH to log in to the machine you want to upgrade. You must log in as root to perform this procedure.
     • Navigate to the folder where you install software using the command: cd /shared/images
     • Install the upgrade to a new volume by running one of the following commands:
       • If you are upgrading a virtual machine: tmsh install sys software image <full name of the iso file> volume hd1.2 create-volume reboot
       • If you are upgrading a BIG-IQ 7000 series platform: tmsh install sys software image <full name of the iso file> volume md1.2 create-volume reboot
     • While the system installs the upgrade to the new volume, you can check on the status of the upgrade using the command: tmsh show sys software status.
     • When the upgrade finishes installing, the machine reboots. Proceed to the next to the last (login) step in this task.
10. To prompt BIG-IQ to reboot into the new software installation volume, select the Reboot into Target Volume check box.
11. Click the Apply button.
    A popup screen opens, prompting you to confirm the installation.
12. Click the Continue button.
13. Wait while BIG-IQ loads the new software and reboots.
    Depending on your configuration and the number of devices you are managing, this could take up to an hour. During this time, it is important that you not interrupt the installation process by restarting services or the server.
14. Log in to the BIG-IQ that will be the secondary BIG-IQ system to confirm that the upgrade succeeded and complete the setup wizard.
    To complete the setup task, you must supply a master key pass phrase that all devices in the logging node cluster must share. Make note of the phrase you use. Each logging node, as well as the primary and secondary BIG-IQ systems must use this phrase before they can join the cluster.
15. If needed, extend the /var partition.
    The default size of the /var file system in a newly installed or upgraded node is 30 GB. This amount of available storage might not be enough to store your data. If you previously extended your disk space, you'll need to do it again after you upgrade, as explained in K16103: Extending disk space on BIG-IQ Virtual Edition.

    Important: Upgrading a node requires at least two volumes, so be sure you can extend the /var file system on both volumes to the same size; otherwise, upgrades might fail.

   • For an existing DSC pair, select Use Existing from the list, and then select the name of your DSC group from the next list.
   • To create a new DSC pair, select Create New from the list, and type a name in the field.
   For BIG-IQ to properly associate the two devices in the same DSC group, the Cluster Display Name must be the same for both members in a group.
   There can be only two members in a DSC group.
6. If this device is configured in a DSC pair, for the Deployment Settings, specify how to handle it:
   • Initiate BIG-IP DSC sync when deploying configuration changes (Recommended): Select this option if this device is part of a DSC pair and you want this device to automatically synchronize configuration changes with the other member in the DSC group.
   • Ignore BIG-IP DSC sync when deploying configuration changes: Select this option if you want to manually synchronize configurations changes between the two members in the DSC group.
7. Click the Add button at the bottom of the screen.
   The BIG-IQ system opens communication to the BIG-IP device, and checks the BIG-IP device framework.

   Note: 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.
8. 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.
9. If in addition to basic management tasks (like software upgrades, license management, and UCS backups) you also want to centrally manage this device's configurations for licensed services, select the check box next to each service you want to discover.
   You can also select these service configuration after you add the BIG-IP device to the inventory.
10. To enable statistics collection for this BIG-IP device, under Statistics monitoring, select the check box next to each service you want to collect statistics for, and then click Continue.
    Note: If you want to enable statistics collection without managing any services, just clear the check boxes for all services.
11. Click the Add button at the bottom of the screen.
12. On the BIG-IQ primary device, at the top of the screen, click System.
13. On the left, expand BIG-IQ DATA COLLECTION and then select BIG-IQ Data Collection Devices.
    The BIG-IQ generates an automatic key pair that you need before the DCD can start collecting and managing statistics.

1. At the top of the screen, click System, and then, on the left, click BIG-IQ DATA COLLECTION and select BIG-IQ Data Collection Cluster.
   • Under Summary, you can view information detailing how much data is stored, as well as how the data is stored.

5. For the Domain, you can type the domain name for the user account configured on the external storage device.
6. For the Storage Path, type the path to the external storage location.
   You can specify the device using the IP address or the host name. Additionally, you need to specify the path to the folder on the external storage device. For example:
   //<storage machine ip-address>/<storage-file-path>
   Note: Remember, the folder you specify must have full read, write, and execute permissions.
7. To test the settings just specified, click Test.
   A message displays to tell you whether the test completes successfully. If it does not, correct the settings and permissions.
8. When the external storage is specified successfully, click Save.

1. Use SSH to log in to the primary BIG-IQ system.
   You must log in as root to perform this task.
2. Determine whether the DCD cluster service restarted by running the following command:
   bigstart status elasticsearch
   In the following example, the DCD cluster has been up and running for less than an hour.

   elasticsearch run (pid 5110) .5 hours
   

3. Determine whether the primary BIG-IQ system rejoined the DCD cluster using the following command:
   curl localhost:9200/_cat/nodes?v
   In the following example, the recently upgraded BIG-IQ system (10.144.73.126) has rejoined the cluster (four DCDs, the primary BIG-IQ, and the secondary BIG-IQ).

   curl localhost:9200/_cat/nodes?v
   host          ip            heap.percent ram.percent load node.role master name
