Abstract
A managed server (srv-10) is powered on by a power controlling unit. The managed server executes a POST process, and transfers a PXE request to a boot controlling unit. The boot controlling unit transfers an HBA vendor determining program. In the managed server, the WWN is set by an HBA vendor-dedicated program corresponding to an HBA vendor, and when a PCI initialization code can not be loaded, the POST process is re-started, and the PXE request is transferred again. The boot controlling unit transfers an NOP program, and the managed server starts an OS with a SAN boot.
Claims9
A controlling method in a management apparatus managing one or a plurality of computers through a network, the method comprising:
- receiving, in the management apparatus, a boot request from a computer;
- transferring a program from the management apparatus to the computer that issued the boot request, in a case that a booting process is executed by the computer, the program setting a unique identifier to a port of a connection apparatus equipped in the computer;
- setting, in the computer, the unique identifier to the port by executing the program;
- checking, in the computer, whether an initialization code of the connection apparatus to re-initialize the connection apparatus can be accessed by executing the program;
- and
- executing, in the computer, when the initialization code can be accessed, the booting process via the port to re-initialize the computer without executing a reset operation of the computer by executing the program.
A computer system comprising:
- one or a plurality of computers;
- and
- a management apparatus managing the one or the plurality of the computers and being connected to the one or the plurality of the computers through a network,
- wherein the management apparatus comprises a boot controlling unit executing boot control for one or a plurality of the computers, and a unit transferring to the computer that issued the boot request, in a case that a booting process is executed by the computer, the program setting a unique identifier to a port of a connection apparatus included in the computer, and
- wherein the computer sets the unique identifier to the port by executing the program;
- checks whether an initialization code of the connection apparatus to re-initialize the connection apparatus can be accessed by executing the program;
- and
- executes, when the initialization code can be accessed, the booting process via the port to re-initialize the computer without executing a reset operation of the computer by executing the program.
A non-transitory computer readable storage medium storing a boot controlling program to cause a management apparatus to execute operations, the management apparatus managing one or a plurality of computers through a network, the operation comprising:
- receiving a boot request from a computer;
- and
- transferring a program setting a unique identifier to a port of a connection apparatus included in the computer that issued the boot request, by the management apparatus;
- wherein the computer sets the unique identifier to the port by executing the program;
- checks whether an initialization code of the connection apparatus to re-initialize the connection apparatus can be accessed by executing the program;
- and
- executes, when the initialization code can be accessed, the booting process via the port to re-initialize the computer without executing a reset operation of the computer by executing the program.
