Error identification and handling in storage area networks

摘要

Storage area network (SAN) components contain a processor configured to provide a first event handling module that can receive an error event at a first hardware component of the storage area network. A database is accessed that contains associations between error event data and potential sources of errors. A plurality of hardware components are identified using the database and error event data. The hardware components are ranked and one is selected based on the ranking. An error notification is sent to a second event handling module of the hardware component. Based upon the response of the second event handling module, an error handling procedure is carried out.

1. A computer implemented method for handling error events relating to a storage area network, the method comprising:
receiving an error event at a first hardware component of the storage area network; using, in response to the error event, a first event handling module operating on the first hardware component to:
access a database containing associations between error event data and potential sources of errors;identify a plurality of hardware components based on similarities between the associations in the database and error event data contained in the error event;generate a ranking for the plurality of hardware components;select, based on the ranking, a particular hardware component from the plurality of hardware components;transmit an error notification to a second event handling module of the particular hardware component of the plurality of hardware components;monitor a response, of the second event handling module to the error notification;carry out an error handling procedure based on the response;perform a self test of the particular hardware component using the second event handling modulecomparing a first version identifier of the database to a second version identifier in order to identify an update to the database; andapplying, in response to a mismatch between the first and second version identifiers, the update to the database.
