Abstract:
1. A method for generating a connection topology for a computer system of a type having at least one server, and at least one device controller coupled to said server through a host bus adapter, said method comprising: (a) querying said server to identify all host bus adapters to said server coupled; (b) querying each identified host bus adapter to identify all device controllers attached to each said identified host bus adapter; (c) issuing a SCSI read connection information command to each said identified device controller through the host bus adapter identifying the host bus adapter WWN to the device controller and requesting a response identifying the WWN for the device controller and for the host bus adapter to which the device controller is connected; (d) receiving, for each said identified device controllers, connection results identifying a first WWN of the device controller and a second WWN of the host bus adapter to which the device controller is connected; (e) storing the returned connection results in a data structure, the data structure comprising a server table having (i) a server entry for each server identified to the computer system that is connected to at least one device controller, each entry having a pointer to a particular host bus adapter connection table, the host bus adapter connection table capable of being different for each entry; and (f) generating a connection topology from the data structure identifying the topology of said computer system including the topology of the at least one server and all controllers that are coupled to said server.
