A host is closed when an administrator chooses to close or lock it. Administrators close a host to upgrade software or to troubleshoot hardware.
Hosts can also be closed when host scavenging has been enabled and the host is no longer idle.
If the host has already been allocated to a consumer to run Symphony work, the host continues to run Symphony workload until the consumer releases the resource. Once the host is released, it no longer accepts new work.
Note that if a scavenged host is closed due to host thresholds being exceeded, the workload is either terminated immediately (if configured for fastrelease) or after a grace period.
