Abstract:
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.
