摘要:
A method to provide redundant accessor availabilty in an automated data storage library. The method provides a data storage and retrieval system comprising one or more data storage devices a robot accessor and a gripper. Either at the same time or at a later time, the user obtains a second gripper and/or a second accessor. The method allows selection and/or authorization for additional support from the second gripper and/or the second accessor upon request and authorization. The redundant accessor capabilities are provided on an honor system for payment for the additional capability, and/or uses a system for tracking the redundant accessor usage, and/or uses license keys or other controls that must be obtained prior to enabling redundant accessor capabilities.
摘要:
A method to partition a data storage and retrieval system into one or more logical libraries, where that data storage and retrieval system includes a library controller, one or more data storage drives and one or more control ports. A data storage and retrieval system which includes a computer useable medium having computer readable program code disposed therein to implement Applicants' method to partition the data storage and retrieval system into one or more logical libraries. A computer program product usable with a programmable computer processor having computer readable program code embodied therein for partitioning Applicants' data storage and retrieval system into one or more logical libraries.
摘要:
A method for assigning element addresses in an automated data storage library includes determining if a data storage device, such as a tape cartridge, belongs to a particular host's cartridge assignment policy. If so, the data storage device is issued a virtual import/export element address taken from a set of non-common virtual import/export element addresses, if available. If no non-common address is available, then a common virtual import/export element address is assigned to the data storage device. If no addresses, either common or non-common, are available, then the data storage device is queued until an address becomes available.
