摘要： An enhanced mechanism for providing data protection for variable length records utilizes high performance block storage metadata. In an embodiment, an emulated record that emulates a variable length record, such as a Count-Key-Data (CKD) record or an Extended-Count-Key-Data (ECKD) record, is generated by a Host Bus Adapter (HBA) of a mainframe system. The emulated record comprises a sequence of extended fixed-length blocks, each of which includes a data block and a footer. A confluence of the footers defines a high performance block storage metadata unit associated with the emulated record and includes a checksum that covers all data blocks and all footers of the entire emulated record. In one embodiment, the checksum is checked during transit of the emulated record between a HBA and a storage subsystem (e.g., by the HBA when the emulated record is received from the storage subsystem, and/or by a switch in the data transfer path), during a hardening step when writing the emulated record to a disk, and/or during a verification step when reading the emulated record from the disk.

摘要： Provided is a method for removing alias addresses from an alias address pool. A plurality of alias addresses are assigned to an alias address pool, wherein the alias addresses in the alias address pool are capable of being dynamically assigned to a device to service I/O requests to the device. An operation is initiated by a process to remove a specified alias address from the alias address pool. An indicator is set to prevent additional processes from removing one alias address from the alias address pool in response to initiating the operation. The specified alias address is removed from the alias address pool.

摘要： Disclosed is a system, method, and program for analyzing proposed interface ports to a device. Failure boundary data is read from the device indicating at least one failure boundary of a proposed interface to the device and a mask is accessed from the device. The accessed mask is applied to the failure boundary data for the proposed interface and existing interfaces to determine at least one failure boundary for the proposed interface and existing interfaces. A determination is made of a number of single points of failure for the proposed interface port from the determined failure boundaries the proposed interface has in common with interface ports currently used to access the device. A further determination is made of a relative availability rating based on the number of single points of failure for each proposed interface port.

摘要： A database management system ensures consistency between primary and mirrored backup copies of a database, despite occurrence of a suspending condition interrupting the normal process of mirroring the primary database. One or more primary controllers are provided, each having a data storage unit with multiple primary data storage devices. Multiple secondary controllers each have multiple associated secondary data storage devices, each secondary controller being coupled to one primary controller. One or more primary databases reside on the primary devices, with a corresponding number of secondary databases residing on the secondary devices. Each secondary database mirrors a corresponding primary database. Either a host, attached to a primary controller, or one of the primary controllers itself, maintains a map cross-referencing each primary and secondary database with the primary and secondary devices containing portions thereof. If a predefined “suspending condition” affecting data mirroring occurs, the host or primary controller consults its map to identify all primary and secondary devices affected by the condition. Then, each primary controller stops all ongoing and future read/writes with each of its affected primary devices. Each primary controller also directs each secondary controller having an affected secondary device to stop mirroring the primary databases stored on that device. Then, the primary controller starts intermediate change recording and resumes read/writes with its primary devices. When the suspending condition ends, each primary controller applies the appropriate logged changes to its secondary database(s) and then reactivates each secondary database.

摘要： Disclosed is a system for performing input/output (I/O) operations with a processing unit. A processing unit, such as a host system, determines a base and associated alias addresses to address an I/O device, such as a direct access storage device (DASD). The processing unit associates the determined base and alias addresses to the I/O device. The association of base and alias addresses is maintained constant for subsequent I/O operations until the processing unit detects a reassignment of the association of base and alias addresses. The processing unit then determines an available base or alias address to use with an I/O operation and may concurrently execute multiple I/O operations against the I/O device using the base and alias addresses.
