Patent number: 10690368Abstract: An information processing apparatus includes a memory and a processor coupled to the memory. The memory stores first information and second information. The first information includes a permission time with respect to each of a plurality of operation states of the information processing apparatus in an activation state. The permission time is a time allowed for switching a substitute apparatus from a standby state to the activation state. The second information includes an activation time required for activating each of a plurality of modules which operate on the substitute apparatus. The processor identifies one permission time corresponding to a current operation state. The processor determines stop modules such that a total time for activating the stop modules is equal to or less than the one permission time based on the second information. The processor instructs the substitute apparatus in the standby state to stop the stop modules.Type: GrantFiled: August 9, 2018Date of Patent: June 23, 2020Assignee: FUJITSU LIMITEDInventors: Yoichi Yasufuku, Mikio Ito, Hiroshi Shiomi, Takako Kato, Yasuhito Kikuchi, Hiroyasu Inagaki, Yukinori Matsukawa

Patent number: 8238204Abstract: In order to facilitate the management of the hardware key of a library apparatus employing the LTO system, a write function of a noncontact memory (CM: cartridge memory) contained in an LTO tape cartridge is implemented in a medium carrying mechanism part of the library apparatus, and during an insertion to a tape drive, the IDs unique to a library control part and to the medium carrying mechanism part are recorded in the non-contact memory and utilized as the hardware key of an encrypting apparatus. The hardware key written once is overwritten (erased) during an ejection, thereby preventing leakage of key information.Type: GrantFiled: September 14, 2007Date of Patent: August 7, 2012Assignee: Fujitsu LimitedInventors: Yoshiharu Itou, Kinya Saito, Kenichi Utsumi, Reisuke Nakagawa, Hitomi Akiyama, Ichirou Sakuma, Hiroyasu Inagaki

Patent number: 7139147Abstract: A drive control apparatus receives an instruction from an upper unit, to mount a predetermined medium onto a predetermined drive unit. If a combination of the predetermined medium and the predetermined drive unit is determined as inappropriate, the drive control unit replies to the upper unit that the predetermined drive unit cannot be used. A combination of a medium and a drive is appropriate if both, the medium and the drive are suitable for any one of encrypted and unencrypted data.Type: GrantFiled: July 25, 2005Date of Patent: November 21, 2006Assignee: Fujitsu LimitedInventors: Mitsuru Yasue, Kinya Saito, Kenichi Utsumi, Reisuke Nakagawa, Hitomi Akiyama, Ichirou Sakuma, Hiroyasu Inagaki, Yoshiharu Itoh
