2.7. Storage Domain Autorecovery in Red Hat Virtualization
Hosts in a Red Hat Virtualization environment monitor storage domains in their data centers by reading metadata from each domain. A storage domain becomes inactive when all hosts in a data center report that they cannot access the storage domain.
Rather than disconnecting an inactive storage domain, the Manager assumes that the storage domain has become inactive temporarily, because of a temporary network outage for example. Once every 5 minutes, the Manager attempts to re-activate any inactive storage domains.
Administrator intervention may be required to remedy the cause of the storage connectivity interruption, but the Manager handles re-activating storage domains as connectivity is restored.
