    SC. Domain Minimization One way to contribute to the security of a Netra 1290 server is to tailor the installation of software to an essential minimum. By limiting the number of software components installed on each domain (called domain minimization), you can reduce the risks of security holes that can be exploited by potential intruders.

    Suspend-Safe and Suspend-Unsafe Devices When DR suspends the operating system, all of the device drivers that are attached to the operating system must also be suspended. If a driver cannot be suspended (or subsequently resumed), the DR operation fails. A suspend-safe device does not access memory or interrupt the system while the operating system is in quiescence.

    Conditions and States A state is the operational status of either a receptacle (slot) or an occupant (board). A condition is the operational status of an attachment point. Before you attempt to perform any DR operation on a board or component from a server, you must determine state and condition.
