  • Error routing in a multi-root communication fabric
    Patent number: 8055934
    Abstract: In one aspect of the present description, in response to detection of a failure of a root server of a storage controller, a switch for input/output adapters may be reconfigured to report errors to a successor root server without reinitializing the input/output adapters. Other features and aspects may be realized, depending upon the particular application.

  • Early notification of error via software interrupt and shared memory write
    Patent number: 7685476
    Abstract: 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.
