How do I unblock a blocked host?

Blocked hosts are handled in different ways, depending on the reason why it was blocked. Generally speaking, if a host becomes blocked, it is not suitable for starting a client's workload units. We recommend discovering the reason why the host was blocked (by searching the service controller log file or the log file for the workload manager), and then attempting to resolve the cause.

To unblock the blocked host, select Remove blocked host from the Platform Management Console.

You can also disable the application and re-enable it. This will unblock all hosts for this application.
CAUTION:

All currently running workload will be terminated if you disable the application.
