Abstract

The invention provides a method for automatically detecting server hardware information. In the method, the detected server is named client end. The client end gets an IP address from the end of the server through a DHCP; and then the client end downloads a custom-built Linux kernel and a ramdisk image file through a TFTP and loads. The client end gets a driving process from the prescheduled hardware information base and automatically loads the driving process, and then the hardware information is gained. After the detecting of the hardware information, the client end initiates a TCP link, and sends the hardware information back to the server end. The hardware information comprises: the quantity of CPU; type, frequency, the size of EMS memory; network card number and MAC address; the quantity of the hardware; type (IDE / SCSI); capacity, a Vendor and a model; the SerialNum of an HCA card an HBA card, VenderId; WorldWildNodeName and WorldWildPortName. With the method, the hardware information of the server can be accurately and quickly gained; the process of manual searching for server hardware arrangement information is simplified; the machines management efficiency is improved.
