摘要： Provided are a method, system, and article of manufacture recovering remnant encrypted data on a removable storage media. An end of data (EOD) marker is detected on a removable storage media, wherein a first encryption key is associated with data preceding the EOD marker. Following the EOD marker, an identifier of a second encryption key associated with data following the EOD marker is read in response to detecting the EOD marker. The identifier is used to access the second encryption key and the second encryption key is used to decrypt the data following the EOD marker.

摘要： Synchronized data is written to magnetic tape while reducing the number of backhitches. A controller detects a pattern of synchronizing events for received data records to be written to tape; writes each transaction of data records to the magnetic tape; accumulates the synchronized transactions in a buffer; and subsequently recursively writes the accumulated transactions of data records from the buffer to the magnetic tape in a sequence. A single backhitch may be employed to place the recursively written accumulated data records following the preceding data, maximizing performance and capacity.

摘要： Provided are a method, system, and program for writing data in a tape medium having wraps. A layout of the tape is provided including at least one segment within a full available length of a first set of wraps for writing user data and at least one segment within a full length of a second set of wraps for writing a work copy of the user data. User data is received to write to the tape medium and detecting is performed as to whether the data being written is occurring in a specified write mode. If the data writing is not occurring in the specified write mode, then writing the received user data to one segment in the first set of wraps. If the data writing is occurring in the specified write mode, then writing a work copy to available full length wraps not having user data.

摘要： A method, system, and computer program product are provided for utilizing target of opportunity to perform at least one special operation while a key session is opened with a key manager for another purpose. The method of recognizing a target of opportunity includes receiving a command to be performed on a removable storage medium and determining if the command requires interaction with the encryption key manager. If it is determined that the command requires interaction with the key manager the command is held off. A request is sent to the encryption key manager. A target of opportunity is recognized by determining if at least one special operation may be performed. If it is determined that at least one special operation may be performed then the at least one special operation and the request are performed.

摘要： A method for determining volume coherency is disclosed herein. Upon completing a first write job to a volume partition, the method makes a copy of a volume change reference (VCR) value associated with the volume. The VCR value is configured to change in a non-repeating manner each time content on the volume is modified. Prior to initiating a second write job to the volume partition, the method retrieves the copy and compares the copy to the VCR value. If the copy matches the VCR value, the method determines that a logical object on the partition was not modified between the first and second write jobs. If the copy does not match the VCR value, the method determines that the logical object on the partition was modified between the first and second write jobs. A corresponding system and computer program product are also disclosed herein.
摘要翻译： 本文公开了一种用于确定卷一致性的方法。 完成对卷分区的第一次写入作业后，该方法将创建与卷相关联的卷更改引用（VCR）值的副本。 每次修改卷上的内容时，将VCR值配置为以不重复的方式进行更改。 在向卷分区启动第二次写入作业之前，该方法将检索副本并将该副本与VCR值进行比较。 如果复制与VCR值匹配，则该方法确定在第一和第二写入作业之间没有修改分区上的逻辑对象。 如果副本与VCR值不匹配，则该方法确定分区上的逻辑对象在第一个和第二个写入作业之间已被修改。 本文还公开了相应的系统和计算机程序产品。

摘要： A system and computer program product are provided for utilizing target of opportunity to perform at least one special operation while a removable storage medium is mounted within a data storage drive for another purpose. The system for recognizing a target of opportunity comprises a tape drive. The tape drive receives a command to mount a tape cartridge in the tape drive, and in response the tape drive mounts the tape cartridge in the tape drive. The tape drive determines if at least one special operation may be performed. If it is determined that at least one special operation may be performed, the tape drive recognizes that a target of opportunity exists. In response to determining that at least one special operation may be performed, the tape drive sends a first notification that the tape drive is to remain in a not ready state. The tape drive performs the at least one special operation, and in response to performing the at least one special operation, the tape drive sends a second notification that the tape drive is in a ready state or an error state.
