Restart data collection device cluster
If too much time elapses between the time you upgrade the data collection devices in your cluster, the cluster communication between data collection devices can fail. If the communication fails, some of the devices can fail to re-join the cluster. If one of the devices does not re-join the cluster, the cluster will not operate. To prevent this scenario, you need to restart the cluster before proceeding.
Note: You must perform this task on each
device in the cluster (that is, each data collection device, the BIG-IQ® Centralized Management device, and the BIG-IQ HA peer).
Once you have restarted the cluster
for each device, you can proceed to the next task.
Recheck data collection device health
You
can use the Settings screen to review the overall health and status of the data
collection devices you've configured. You can use the data displayed on this screen both
before and after an upgrade to verify that your data collection device cluster
configuration is as you expect.
Activate data collection devices services
To upgrade your data collection
devices, you deactivated all data collection device services. Once the upgraded software
is installed, you must activate the services before you can resume normal operation.
Note: Perform this action
on the BIG-IQ® Centralized Management device; not the data
collection device (DCD).
This restarts the services on your
DCDs.
