A method of providing error notification in a storage subsystem includes writing a first defined value by a host adapter of the storage subsystem to a system management interrupt (SMI) register to generate a hardware interrupt, registering and handling the hardware interrupt by a kernel module of the storage subsystem, writing a second defined value to a shared memory location of the storage subsystem by the kernel module, and reading a shared memory offset value by the host adapter. A system for providing error notification in a storage subsystem includes a controller including a serial management interface (SMI) register subcomponent, a first processing component connected to the controller having a kernel module, and a second processing component connected to the controller executing host adapter software.
