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.

Information processing apparatus and information processing system

A library apparatus includes a rack that holds a magazine loaded with plural tape cartridges, the rack including an insertion slot through which the magazine is inserted, a conveying mechanism that attaches the plural tape cartridges to the magazine and detaches the plural tape cartridges from the magazine, the conveying mechanism including a reader for reading an identifier provided on each of the plural tape cartridges, and a control device that moves the conveying mechanism, prior to the magazine being inserted into the insertion slot, to an identifier reading position enabling the reader to read the identifiers as the magazine is inserted through the insertion slot.

Library apparatus

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.

Apparatus and method for managing key in library apparatus

Disclosed is a method, for erasing data from a magnetic tape storage medium () housed in a cartridge () containing a memory in which are stored the last written track position (yy) of the last written, most recent information and the last track position (xx) of past information written in the past and remaining unerased, comprising: the step of reading out of the memory () the last written track position of the most recent information and the last track position of the past information; the step (S) of determining whether the data should be erased up to the last written track position of the most recent information or up to the last track position of the past information; and the step (S, S) of erasing the data up to the determined position, thereby shortening the data erase time of the magnetic tape while completely solving a security problem by making provisions to completely erase the data of the most recently written information or the data of the past information written in the past and remaining unerased.

Method for erasing data from magnetic tape storage media

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.
