A data storage library system includes a data storage library, at least one environmental conditioning unit, at least one data storage drive retained within the data storage library, and at least one access door for providing access to an interior portion of the data storage library. The system also includes a library controller, wherein the library controller is configured to initiate a service mode prior to and during a service procedure performed within the data storage library, and further wherein at least one operational state within the at least one data storage drive is changed during the service mode. The change in the at least one operational state may be, for example, an increase in temperature within the at least one data storage drive, or the insertion of a data storage cartridge into the at least one data storage drive during the service mode.

Data storage library with service mode for protecting data storage drives

A data storage library system includes a data storage library having at least one library frame, at least one environmental conditioning unit associated with the data storage library and configured to control one or more interior environmental conditions within the at least one library frame, and at least one access door for providing access to an interior portion of the at least one library frame. The system also includes a library controller configured to initiate a service mode prior to and/or during a service procedure performed within the at least one library frame, wherein the service mode comprises configuring the at least one environmental conditioning unit to adjust the one or more environmental conditions within the at least one library frame toward one or more exterior environmental conditions outside of the data storage library. Optionally, a lock and/or indicator (visual and/or audible) may control access to the interior of the library frames. Associated methods of servicing a data storage library are disclosed.

Data storage library with service mode

A data storage library system includes at least one data storage library, the at least one data storage library comprising at least one library frame, wherein the at least one library frame has at least one environmental conditioning unit configured to control one or more environmental conditions within the at least one library frame. The system also includes at least one access door for providing access to an interior portion of the at least one library frame, a library controller, and at least one louver, where the louver may be selectively moveable to control a communication pathway for external air to enter the at least one library frame. In one embodiment, the at least one louver may be controlled by the library controller to automatically open when it is detected that the one or more access doors are opened, and to close the louver when the one or more access doors are closed.

Data storage library with positive pressure system

A data storage library system includes at least one data storage library comprising at least one library frame and at least one environmental conditioning unit, the at least one environmental conditioning unit configured to control one or more environmental conditions within the at least one library frame. The system further includes at least one access door for providing access to an interior portion of the data storage library, a library controller, and at least one warning indicator associated with the data storage library and in electronic communication with the library controller. The at least one warning indicator is configured to provide an indication to an operator when the conditions within the data storage library are such that the at least one access door may be opened and when the conditions within the data storage library are such that the access door should not be opened.

Data storage library with interior access regulation

A computer program product for implementing write procedures using an estimated best setting in a first run, the computer program product comprising a computer readable storage medium having program instructions executable by a tape drive to cause the tape drive to perform a method comprising: receiving, at the tape drive, a request for a write operation to be performed in the tape drive; determining, by the tape drive, a capacity margin ratio of the tape drive; determining an optimum a write procedure based at least in part on the capacity margin ratio; and invoking the optimum write procedure in response to determining the optimum write procedure. The optimum write procedure is selected from the group consisting of: a backhitch write procedure, a same wrap backhitchless flush (SWBF) write procedure, and a recursively accumulating backhitchless flush (RABF) write procedure.

Write procedure using estimated best setting in first run

In one general embodiment, a tape drive system includes: a read channel; a write channel; logic configured to receiving a request for a write operation to be performed in a tape drive; logic configured to determine an optimum a write procedure in response to receiving the request, the determining being based on expected writing times of each of a plurality of write procedures and an expected transaction size of a next write operation; and logic configured to invoke the determined optimum write procedure in response to determining the optimum write procedure.

A data storage library system and method comprising at least one data storage library, the at least one data storage library comprising one or more library frames associated with the one or more library frames and at least one environmental conditioning unit configured to control one or more environmental conditions within the one or more library frames. At least one component locker is housed in an interior portion of the one or more library frames, and the at least one component locker is configured to retain one or more replacement components for use in the at least one data storage library.
