摘要： Deleting a data volume from a storage system and freeing its storage space to make it available to be allocated to a new volume is accomplished by only zeroing associated metadata for the tracks contained in the freed storage space which is then reused in a new volume allocation and an attempt is made by the new volume to read a first record R0 of a track. A determination is made as to whether a first user record R1 of the volume is stale If the first record R0 is stale. If record R1 is stale, the metadata or track format description (TFD) is modified whereby the entire track is indicated as being uninitialized and the first record R0 is uninitialized. If record R1 is not stale, the first record R0 is regenerated and the TFD is modified whereby the entire track is indicated as being initialized.

摘要： A method to initialize information disposed in an information storage and retrieval system comprising a data cache and one or more information storage media comprising a plurality of addresses. The method receives an initialization command, where that initialization command comprises a range of addresses and, optionally, an initialization pattern, where the plurality of addresses includes the range of addresses. The method forms and saves state information, where that state information includes the initialization pattern, and generates and saves a plurality of indicators, where that plurality of indicators includes an indicator for each track comprising the range of addresses. The method sets each of those indicators to a first value thereby indicating special handling, and provides an ending status signal, such that the receiving step, forming step, generating step, setting step, and providing step are performed substantially synchronously.

摘要： A system and technique for storing data in a cache memory in record format and in track format. Space is allocated in cache memory for the storage of data in track format. Additional space is allocated for the storage of data in record format. Data is stored in both formats. The most current data is identified and addresses are generated for each record of data. Access to individual records of data is facilitated through a track information block in which pointers are stored for the most current records whether stored in track format or record format. The track information block facilitates a rapid storage and retrieval of data in either format. In a specific implementation, data is stored in either format in cache using a scatter index table. The scatter index table and associated track directory entries are stored in a shared control array. Each track directory entry points to a track slot header in a cache. The track slot header points to an area (segment) in the cache memory in which selected data resides. The track slot header also points to a track information block associated with the selected segment. The track information block identifies the location selected records in the segment in track format or record format.
摘要翻译：一种以记录格式和轨道格式将数据存储在高速缓冲存储器中的系统和技术。空间被分配在高速缓冲存储器中用于以轨道格式存储数据。分配用于以记录格式存储数据的附加空间。数据以两种格式存储。识别最新的数据，并为每个数据记录生成地址。通过轨道信息块可以访问数据的单独记录，其中存储指针用于最新的记录，无论是以轨道格式还是以记录格式存储。轨道信息块有助于以任一格式快速存储和检索数据。在具体实现中，使用散列索引表将数据以任一格式存储在高速缓存中。分散索引表和关联的轨道目录条目存储在共享控制数组中。每个轨道目录条目指向高速缓存中的轨道槽头。轨道槽头指向所选数据所在的高速缓冲存储器中的区域（段）。轨道槽头还指向与所选择的段相关联的轨道信息块。轨道信息块以轨道格式或记录格式识别段中所选择的记录的位置。

摘要： A cached DASD controller is illustrated which is attached to a high speed serial channel, such as an optical fiber channel. The data rate of the serial channel is much greater than the data rate of a DASD connected to the controller. The serial channel has a relatively long propagation time such that synchronous operations between the host processor 10 and the DASD cannot be efficiently performed. Operation of a data transfer, whether read or write between the host processor 10 and the DASD is monitored. Whenever reading a copy of the track contents stored in cache or the DASD reaches either an index mark, a break point from a roll mode operation or certain write operations occur resulting in predetermined data being stored in cache, then a GOCACHE flag is set in a control portion of the controller. The device operations are then momentarily idled while cache to host processor data transfer operations are enabled.
