Abstract:
A method of hot swapping a programmable mass storage adapter connected to an operational computer wherein the operational computer has at least one programmable data processor for receiving requests from a central processing unit and for controlling power to the programmable mass storage adapter in response to requests from the central processing unit, the method comprising:connecting the programmable mass storage adapter to a plurality of I/O devices;executing a statically loaded adapter driver which accepts requests to suspend or restart communications to the programmable mass storage adapter;suspending all communication to the programmable mass storage adapter;disabling power to the programmable mass storage adapter, wherein the programmable data processor determines whether a received request is to disable power;removing the programmable mass storage adapter from the operational computer;inserting a new programmable mass storage adapter into the operational computer;enabling power to the new programmable mass storage adapter, wherein the programmable data processor determines whether a received request is to enable power; andrestarting communications between the operational computer and the new programmable mass storage adapter.
