Storage device system and storage device system activating method
First Claim
1. A storage device system comprising:
- a plurality of storage devices in which information is stored;
a storage device control section for controlling storage of information in said plurality of storage devices;
a connection unit connected to said storage device control section;
a first processor that is connected to an external local area network (LAN), which is external to said storage device system, and that converts data of a file access form received over said external LAN into data of a block access form;
a second processor that is connected to said storage device control section via said connection unit, that accesses said plurality of storage devices via said connection unit and said storage device control section in response to data of the block access form issued from said first processor, and that controls activation of said first processor including resetting said first processor by said second processor; and
a management terminal that is connected to the first processor and the second processor via an internal LAN,wherein said resetting said first processor by said second processor includes stopping supplying power to said first processor, re-supplying power to said first processor and activating a Basic Input/Output System (BIOS) of said first processor,wherein said second processor issues a request for start of hardware diagnosis of said first processor to said first processor,wherein said first processor performs hardware diagnosis in response to the hardware diagnosis start request issued from said second processor,wherein the first processor stores respective media access control (MAC) addresses, which are assigned to ports of the internal LAN, in respective communication memories,wherein the management terminal acquires the MAC addresses assigned to the first processor from the second processor at regular intervals, until the power supply of the management terminal is turned on again,wherein the second processor verifies whether disk drives have spun disks so as to determine whether the storage devices are usable, and detects whether the disk drives have completed spinning the disks,wherein the first processor issues a network boot request to a network boot server implemented in the management terminal,wherein the management terminal receives the network boot request over the internal LAN, andwherein the first processor instructs the second processor to start disk booting.

Abstract
A storage device system has a plurality of storage devices for storing information; a storage device control section that controls storage of information in the storage devices; and a connection unit connected to the storage device control section. Furthermore, the storage device system has a first communication control section that includes a first processor which is connected to the storage device control section via the connection unit and also connected on a first network external to the storage device system, which converts information of a first form received over the first external network into information of a second form, and which issues a request for access to the storage devices; and a second processor which accesses the storage devices via the connection unit and the storage device control section in response to the access request issued from the first processor, and which controls activation of the first processor.

16. A method of activating a storage device system, wherein the storage device system comprises a plurality of storage devices in which information is stored, a storage device control section which controls storage of information in said plurality of storage devices, a connection unit connected to said storage device control section, a first processor that is connected to an external local area network (LAN), which is external to said storage device system and that converts data of a file access form received over said LAN into data of a block access form, a second processor that is connected to said storage device control section via said connection unit, and that accesses said plurality of storage devices via said connection unit and said storage device control section in response to the data of the block access form issued from said first processor, and a management terminal that is connected to the first processor and the second processor via an internal LAN, said method comprising the steps of:
-
controlling, by said second processor, activation of said first processor including resetting said first processor by said second processor, wherein said resetting said first processor by said second processor includes stopping supplying power to said first processor, re-supplying power to said first processor and activating a Basic Input/Output System (BIOS) of said first processor; issuing, by said second processor, a request for start of hardware diagnosis of said first processor to said first processor; performing, by said first processor, hardware diagnosis in response to the hardware diagnosis start request issued from said second processor; storing, by the first processor, respective media access control (MAC) addresses, which are assigned to ports of the internal LAN, in respective communication memories; acquiring, by the management terminal, the MAC addresses assigned to the first processor from the second processor at regular intervals, until the power supply of the management terminal is turned on again; verifying, by the second processor, whether disk drives have spun disks so as to determine whether the storage devices are usable, and detecting, by the second processor, whether the disk drives have completed spinning the disks; issuing, by the first processor, a network boot request to a network boot server implemented in the management terminal; receiving, by the management terminal, the network boot request over the internal LAN; and instructing, by the first processor, the second processor to start disk booting. - View Dependent Claims (17, 18, 19)
