    摘要: In one embodiment, a method for accessing host data records stored in a virtual tape storage (VTS) system includes receiving a mount request to access a host data record, determining a starting logical block ID (SLBID) corresponding to the requested host data record, determining a physical block ID (PBID) that corresponds to the SLBID, accessing a physical block on a tape medium corresponding to the PBID, and outputting the physical block corresponding to the PBID without outputting an entire logical volume that the physical block is stored to. According to another embodiment, a VTS system includes random access storage, sequential access storage, support for a virtual volume, a storage manager having logic for determining a PBID that corresponds to a SLBID, and logic for copying a portion of a logical volume from the sequential access storage to the random access storage without copying the entire logical volume.

    摘要: Various method, system, and computer program product embodiments for selective device access control in a data storage system are provided. In one such embodiment, a plurality of access groups associated with logical devices used to access the data storage system is initialized. Each of the plurality of access groups corresponds to a range of the logical devices. An access group name of one of the access groups is bound to a logical volume of the data storage system at a volume creation. The logical volume, once bound to the access group name, is granted access by those of the logical devices in a range of the logical devices corresponding to the one of the access groups.

    摘要: A method and apparatus for handling multi-volume datasets in a tape storage system are disclosed. In response to a write request for a multi-volume dataset, the information of the multi-volume dataset are captured by intercepting and deciphering a set of volume mount commands. Otherwise, the information of the multi-volume dataset are captured by snooping header information from a previous volume listed in a header of the multi-volume dataset. A chain of logical volume names that belongs to the multi-volume dataset is then built. Finally, the chain of logical volume names is then stored in a chain database.

    摘要: A system and method for guaranteeing overwrite of expired data in a media device, the data being organized according to logical units provided on media devices organized as physical volumes. The method comprises the steps of: maintaining information associated with a status of a physical volume, and updating a physical volume's status information based upon a combination of that volume's prior status and that volume's current status; specifying a time duration that expired logical unit data may remain on a physical volume; based upon the volume's updated status information, determining whether a selected volume has expired data longer than the specified time duration; and, overwriting contents of the volume having data that has expired longer than the specified time duration.

    摘要: A method to maintain information by assigning one or more storage attributes to each of a plurality of logical volumes. The method writes a first portion of a dataset to a first logical volume. The method assigns one or more storage attributes to that first logical volume. When the logical end of volume for the first logical volume is approaching, Applicants' method mounts a second logical volume, and continues writing the dataset to that second logical volume. The method assigns the same one or more storage attributes to the second logical volume.
