Locked and Unlocked Hosts

When the N1 Service Provisioning System software performs an operation on a host, it locks the host, preventing other plans from operating on it at the same time. Locking a host ensures that one operation, such as an installation, does not undo or overwrite the effects of another. It ensures that the provisioning software can accurately determine the status of a host at any time.

The provisioning software manages the lock automatically. You never need to explicitly lock or unlock a host yourself. However, if the provisioning software indicates that a host is locked, you should wait until its status changes before you try to run a new plan on it.
