Upgrading a BIG-IQ System with a Data Collection Device Cluster
What happens during a BIG-IQ and Data Collection Device cluster upgrade?
From the primary BIG-IQ, the automatic upgrade process performs the following sequence of tasks:
- Breaks the high availability relationship with the secondary BIG-IQ (if present).
- Upgrades the devices in
the Data Collection Device (DCD) cluster. The process starts by checking the statistics retention policy for the
cluster and checking that the DCD cluster is healthy. Then, for each device in the DCD
cluster:
- Confirms disk space is sufficient for the upgrade.
- Stops snapshot creation.
- Deactivates data collection services for the DCD.
- Upgrades the DCD to the latest version.Note: If the /var partition for any of the devices in your cluster was extended before you upgraded, you must extend the/var partition for that device before the upgrade will proceed. For details on extending a disk volume, refer to Resizing VE Disk Volume Workflows in the F5 BIG-IQ Centralized Management Disk Space Management guide on support.f5.com.
- Confirms that the DCD is back in service.
- Reactivates data collection services.
- After the Data Collection Devices have all been upgraded, the process automatically upgrades the primary BIG-IQ.
Upgrade the primary BIG-IQ system and the DCD cluster to v6.1.0
You upgrade BIG-IQ and the devices in your DCD cluster to the latest version from the primary BIG-IQ system.
Upload the latest version of the software image to the secondary BIG-IQ
You upload the BIG-IQ version software image to the secondary BIG-IQ system to make it available for this upgrade.
Manually upgrade the secondary BIG-IQ to the latest version
The primary BIG-IQ is upgraded automatically, directly after the devices in the DCD cluster are finished upgrading, but you have to manually upgrade the secondary BIG-IQ system.
