A quorum data collection device (DCD) makes the
deciding vote for which BIG-IQ will become active if communication is disrupted between
the components of the BIG-IQ high availability configuration. If the quorum DCD comes
back up (even up to 10 hours later), it will automatically rejoin the HA auto failover
configuration. But when the quorum DCD is down, automatic failover cannot occur. It's
important to get the quorum DCD back online as quickly as possible. If the quorom DCD is
unrepairable, perform these steps.
