Abstract: Embodiments include methods, apparatus, and systems for managing host logins to storage systems.

Abstract: In one embodiment, a method of diagnosing an error in a cartridge drive, comprises detecting an occurrence of a defined event in a cartridge drive, in response to the defined event, initiating an analysis routine of at least one event log from the cartridge drive, and invoking an intervention routine when the analysis indicates that the defined event represents a failure threat.

Abstract: Methods and apparatus are disclosed for managing device reservation. In one embodiment, upon receiving a device command from a first host, a device targeted by the device command is reserved for the first host and a reservation time period for expiration of the reservation status is set.

Abstract: Embodiments include methods, apparatus, and systems for managing a storage library with removable media. One method includes providing to an administrative console identification of host computers attempting to access a tape drive in a tape library; determining, from input at the administrative console, access rights for each of the host computers attempting to access the tape drive; and transmitting the access rights to the tape drive in order to configure the tape drive to determine which of the host computers are authorized to access the tape drive.

Abstract: Embodiments include methods, apparatus, and systems for switching firmware images in storage systems.

Abstract: A Transparent Peripheral File System (TPFS) includes a Peripheral File System Adapter (PFSA) which communicates with a host operating system at the vnode level of file operation by packaging such communications for transmission over an I/O system interface, such as SCSI. A file peripheral system remote from the host and in a peripheral relation thereto is responsive to the PFSA, without an intervening file server. The peripheral file system produces hardware commands for the mass storage device whose space it manages. The peripheral file system may be embedded in a mass storage device, a lump in the interconnecting interface cable, or a smart interface card in the backplane of the host. The peripheral file system may include a daisy chain connection to allow the propagation of vnode communication to other peripheral file systems. In this way a hierarchy of peripheral file systems may be physically mounted to one another in a way that corresponds to how they are logically mounted.
