Abstract
A method is disclosed for updating a code image for a communication adapter. The apparatus includes a save module, an update module, and a restore module. The save module saves configuration data associated with a connection at a communication adapter. The update module updates a code image on the communication adapter. The restore module restores the configuration data in response to the code image update. Advantageously, the apparatus eliminates the need for conventional host recovery, including relogin and reestablishment of paths and connections, after the code image update.
Claims7
A signal bearing storage medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform operations to update a code image, the operations comprising:
- saving configuration data associated with a connection at a communication adapter;
- updating a code image on the communication adapter;
- restoring the configuration data in response to the code image-update;
- saving login data in a login data structure prior to the code image update;
- and
- wherein restoring the configuration data comprises re-registering a plurality of remote ports with a plurality of local ports after the code image update according to the login data in an order substantially similar to an order before the code image update, wherein communication is reconnected using the restored configuration data.
A method for deploying computer infrastructure comprising integrating computer-readable code into a computing system, wherein the code in combination with the computing system is capable of updating a code image by performing the following:
- saving configuration data associated with a connection at a communication adapter;
- updating a code image on the communication adapter;
- restoring the configuration data in response to the code image update;
- and
- wherein restoring the configuration data comprises re-registering a plurality of remote ports with a plurality of local ports after the code image update in an order substantially similar to an order before the code image update, wherein communication is reconnected using the restored configuration data.
