Abstract: System and method embodiments for monitoring data integrity among multiple sysplexes that share data sets on a DASD are provided. The virtual volume record (VVR) for each data set on DASD is configured with additional access fields that provide such information as the access mode (serial or multi-access), whether multiple systems have opened the data set, the names of an original sysplex and any additional sysplexes to open the data set, the names of the opening systems in each sysplex, job name and time stamp and a usage counter for each sysplex. Additional access logic in the OS on each system defines specific actions to be taken by the system OS when executing an “open” or “close” including reading and updating information in the additional access fields and generating error, warning or information messages to diagnostic logs. This allows serialization to be enforced among the sysplexes and for error messages to be issued for any system outside the original sysplex that tries to open the data set.

Abstract: A system and method are provided for performing storage operations relating to a first secondary copy of electronic data. A storage policy or storage preferences may dictate that a replication copy should be used in storage operations performed to a particular client, sub-client, data, media or other item. Based on the storage policy, when a new client, sub-client, data, media or other item is received, a media agent determines whether there is a replication copy of the item. In the absence of a replication copy, one may be created. The replication copy may be provided by a third party application, or created by the client or a storage management system component. Information regarding the replication copy and its corresponding first secondary copy may be stored in a database. To optimize use of system resources, storage operations relating to the first secondary copy may be performed using the replication copy instead of the first secondary copy.

Abstract: An intelligent write command routine improves the operational efficiency of a data storage device (DSD) by avoiding media access of the disk when a logical block address (LBA) and the physical sector are unaligned, thus reducing write time. When a write command is received by the DSD from the host, the intelligent write command routine maintains the read data of the read buffer, instead of clearing the read buffer and performing a read of the target sector on the disk per standard protocol. The intelligent write command copies the necessary adjacent sector data from the read buffer as a data patch to the write buffer to splice around the write data received with the write command. Following each write command, the data written to the disk in the write buffer is copied to the read buffer. The read buffer is maintained with the most current data on the disk and does not need to be flushed unless the LBA of the write command is beyond the data ranges stored in the read buffer.
