20140101432 | Detection of Component Operating State by Computer - A mechanism is provided for detecting an operating state of a component. A CLI command is transmitted via a command line interface to the component. An output character string is received responsive to the CLI command. A set of significant character substrings is dissected from the output character string, where each significant character substring comprises a label character string indicating a meaning of the output character string and a data character string expressing data of the output character string. A regular expression corresponding to each significant character substring is set thereby forming a set of regular expressions. A difference is calculated between each of the set regular expressions and each significant character substring corresponding to the regular expression as a character string distance. Each calculated character string distance is compared to a corresponding predetermined threshold and the operating state of the component is output based on results of the comparison. | 04-10-2014 |
20140149899 | METHOD FOR DISPLAYING OPERATION STATES OF MODULES INCLUDED IN COMPUTER SYSTEM - A method for obtaining and displaying operation states of a plurality of modules of a system. The operation state of one module that is carrying out a current function is acquired along with the operation states of a module set that is being used by the one module in carrying out its current function, wherein the module set may itself include a plurality of individual modules. Thereby, the latest operation states of the one module and its module set are acquired without inquiring of the operating state of each individual module that makes up the one module and its module set. Thus, the latest operation states of the individual modules included in the system can be displayed without imposing extra loads on the modules, i.e., without imposing extra negative influence on the current function being carried out, and/or on essential operations of the system. | 05-29-2014 |
20140164693 | METHOD OF WRITING A FILE TO A PLURALITY OF MEDIA AND A STORAGE SYSTEM THEREOF - According to one embodiment, a method for writing a file to a plurality of media includes loading a parent medium into a first drive to retrieve ID information about the parent medium from metadata, writing a first file part to the parent medium and, at about a same time, saving a file name, attribute information, and attribute information about the first file part to the parent medium as metadata, loading a child medium into a second drive in order to write subsequent file parts and retrieving ID information about the child medium from metadata, writing the subsequent file parts to the child medium and, at about a same time, saving the ID information and attribute information about the subsequent file parts to the parent medium, and additionally saving the ID information about the child medium and the attribute information about the subsequent file parts as metadata in the child medium. | 06-12-2014 |
20140181425 | METHOD FOR DIVISIONALLY MANAGING FILES ON A USER BASIS, AND A STORAGE SYSTEM AND COMPUTER PROGRAM PRODUCT THEREOF - According to one embodiment, a method for a plurality of users to write at least one file to a medium in such a manner that the file is divisionally managed in a system environment in which an input/output control is performed on a storage system includes saving, in the medium as metadata, a user identifier (ID) for identifying a user and file attribute information about the file managed by a user associated with the user ID, and writing, as data, the file managed by the user to the medium as indicated by the file attribute information. In other embodiments, a writing program product, a reading program product, and a system are presented that allow a plurality of users to write at least one file to a medium in such a manner that the file is divisionally managed in a system environment. | 06-26-2014 |
20140379980 | SELECTIVE DUPLICATION OF TAPE CARTRIDGE CONTENTS - A copy-source tape storage medium is prepared and includes a index partition for storing updated file metadata and associated metadata indexes and a data partition (DP) for storing valid data and associated valid data indexes and for storing invalid data that has changed or has been deleted or has been invalidated by the update and for storing associated invalid data indexes. Metadata indexes are retrieved and analyzed and a valid record number list indicating a range of record numbers of valid data is created. Records are read from the DP and data in records corresponding to record numbers not included on the valid record number list is replaced with meaningless data which is written to a copy-destination tape storage medium. Records corresponding to record numbers included on the valid record number list are copied to the copy-destination tape storage medium without alteration. | 12-25-2014 |
20150022917 | ADAPTING TRANSFER RATE OF CACHED DATA TO PREVENT STOPPAGE OF DATA TRANSMISSION - A file system to controls access to a tape library that selectively loads and unloads a plurality of cartridges from a plurality of slots to a drive for transmitting to the file system archived data retrieved from a particular cartridge. The file system includes a cache and receives a request from a requestor to access the tape library, estimates a first data transfer rate from an anticipated tape library operation completion duration and from a capacity of cached data to be transmitted from the cache to the requestor, initiates access to the tape library, and adapts the first data transfer rate to a second data transfer rate to transmit the capacity of the cached data to the requestor throughout the anticipated tape library operation completion duration. | 01-22-2015 |
20150127616 | Support for WORM Cartridges Realized by Linear Tape File System (LTFS) - When a WORM cartridge is formatted for Tape File System (LTFS) in advance, such as prior to shipment, Linear Tape File System Library Edition (LTFS LE) is expanded by software to reduce consumption of the index partition and to support elimination of the appending of unnecessary data. More specifically, instead of recording metadata in the index partition during normal unmounting, the metadata is recorded in separate local storage such as on hard disk drive (HDD), and the index partition is updated only when the cartridge is ejected from the library. In this way, the present invention is able to significantly reduce the frequency of index partition updates. Because an update occurs only when the user intentionally ejects a cartridge, overflow of the index partition before overflow of the data partition can be prevented. | 05-07-2015 |
20150138665 | Writing and Reading Data in Tape Media - A mechanism is provided for determining storage device speed based on a ratio of data compression. A bandwidth (B) is identified between a storage device accessing storage medium and a host application requesting access to data on the storage medium. A host side transfer rate is identified, where the host side transfer rate (HSTR) is a rate of data transfer between the host application and the storage device. For each data set in a set of data sets of a record, a ratio of data compression (R) is identified for the data set; a compression considered host side transfer rate (CCHSTR) is determined; and the storage device speed is set to the compression considered host side transfer rate (CCHSTR) for transmitting the data set to the host application. | 05-21-2015 |
