ABSTRACT:
Techniques are disclosed for resetting agents in a computer system without requiring the computer system, or partitions thereof, to be reset. In one embodiment, each agent in the system is associated with a corresponding partition. A reset signal directed to an agent is redirected to a reset type selector which determines whether the partition associated with the agent is in a run state (an “unsafe run state”) in which resetting the agent will cause the partition to crash. If the partition is in an unsafe run state, a soft reset is performed on the agent. Otherwise, a hard reset is performed on the agent. If performing a soft reset does not solve the problem that was the impetus for the reset signal, the partition may be brought into a safe run state before performing a hard reset on it.
