An apparatus, system, and method are disclosed for performing data library background operations. The present invention teaches one or more data storage drives capable of entering a phantom load mode and a library controller capable of initiating the phantom load mode for the data storage drives. The phantom load mode operates to hide the media status of the data storage drives from host computers during background operations involving the data storage drives. In certain embodiments, the data storage drives exit the phantom load mode as a result of a media unload request. In some embodiments, the library controller receives a media load request from a host computer during the background operation and completes the media load request upon completion of the background operation.

Provided are a method, system, and article of manufacture for configuring a storage drive to communicate with encryption and key managers. A storage drive receives a request to access a coupled removable storage media for drive operations. The storage drive obtains encryption status for the coupled removable storage media from an encryption manager. The storage drive determines from the obtained encryption status whether to encrypt the coupled removable storage media to access. The storage drive obtains at least one key from a key manager in response to determining to encrypt with respect to the coupled removable storage media. The storage drive performs data operations using the at least one key to encrypt data.

An apparatus and method are disclosed for managing component identifiers in a data storage system. The apparatus includes a recognition module, a receiving module, a comparison module, and an update module. The recognition module recognizes newly installed components. The receiving module receives a component identifier stored on the newly installed component. The comparison module compares the identifier of the newly installed component with one or more component identifiers stored in a computer system memory. The update module updates the one or more component identifiers stored in the system memory based upon the identifier of the newly installed component.

摘要:
Provided is a method, system, and program for storing data in a storage medium. A layout of a storage medium including a first and second user data sections is provided, wherein the first user data section comprises a faster access storage space than the second user data section. A determination is made of a first set of data to be accessed with less delay than a second set of data. The first set of data is written to the first user data section and the second set of data is written to the second user data section.

Provided are a method, system, and article of manufacture for rekeying encryption keys for removable storage media. A rekey request is received for a coupled removable storage media, wherein encryption on the coupled removable storage media uses a first key and wherein the rekey request indicates a second key. The first key and the second key are accessed in response to the rekey request. The first key is used to perform decryption for the coupled removable storage media and the second key is used to perform encryption for the coupled removable storage media.

In an automated data storage library, selective encryption for data stored or to be stored on removable media is provided. One or more encryption policies are established, each policy including a level of encryption one or more encryption keys and the identity of one or more data cartridges. The encryption policies are stored in a policy table and the encryption keys are stored in a secure key server. A host requests access to a specified data cartridge and the cartridge is transported from a storage shelf in the library to a storage drive. Based on the identity of the specified cartridge the corresponding encryption policy is selected from the table and the appropriate encryption key is obtained from the key server. The storage drive encrypts data in accordance with the key and stores the data on the media within the specified data cartridge.

Disclosed are a system, a method, and article of manufacture to provide for managing data storage media to provide secure storage of the data storage media in an automated data storage library. A logical library partition vault is created in the automated data storage library that is not accessible by any host computer. Data storage media in the logical library partition vault may only be accessed by an operator using a secure means. The logical library partition vault may comprise various components of the automated data storage library by assigning storage shelves, service bays, data storage media, data storage drives or other library components to the logical library partition vault.
摘要:
In a distributed system of modules in a network, each module having an associated processor node comprising a processing unit for operating the associated module. The processing unit comprises a processor interface for communication in the network; and nonvolatile memory for storing code for the processing unit for operating the associated module, and for storing backup code for at least one other processing unit of another processor node in the network, the backup code for operating an associated module of the another processor node. In response to a request, the processing unit supplies the backup code to a processor node to be used to restore the code for operating the module associated with the requesting processor node.
