摘要:
A channel path error correction system includes a processor with one or more channels and a switch operatively coupled to the one or more channels of the processor. The system also includes an I/O device including one or more ports, the I/O device being operatively coupled to the switch by the one or more ports; a plurality of control units. Each control unit includes at least one of the channels and at least one of the ports and a memory operable for storing information relating to detected channel path errors associated with each of the plurality of control units.

摘要:
A host implement a method for controlling a dynamic transition of the host from a current operation mode to a target operation mode. The method involves the host receiving an operation mode transition request to transition a logical representation of a storage subsystem as maintained by the host from the current operation mode to the target operation mode, and the host reconfiguring the logical representation of the storage subsystem to the target operation mode based on the operation mode transition request exclusive of a re-IPLing of an operating system of the host.
