Patent ID: 8281057

Claim:
An information processing apparatus including a controller comprising: a first host bus adaptor which has a first storage section and expands a function of the information processing apparatus, and multiple first input/output devices connected to the first host bus adaptor, wherein the first host bus adaptor includes a first computer processor that activates a first data collection inquiry process between when the information processing apparatus is powered and when the controller of the information processing apparatus, according to an open boot program (OBP), requests device information by way of a driver to the first host bus adaptor, that executes the first data collection inquire process to issue a first inquiry to each of the first input/output devices, and that stores a first response to the first inquiry obtained from each of the first input/output devices in the first storage section; and a second host bus adaptor which has a second storage section and expands a function of the information processing apparatus, and multiple second input/output devices connected to the second host bus adaptor, wherein the second host bus adaptor includes a second processor that activates a second data collection inquiry process between when the information processing apparatus is powered and when the computer processor of the information processing apparatus, according to an open boot program (OBP), requests device information by way of a driver to the second host bus adaptor, that executes the second data collection inquire process to issue a second inquiry to each of the second input/output devices independently from the first inquiry, and that stores a second response to the second inquiry obtained from each of the second input/output devices in the second storage section.
