Abstract: A data structure maintained in a computational device stores how many control areas splits have occurred to store a data set, wherein each control area split causes an addition of a single new control area. A command is received to add a new data record to the data set. A determination is made as to whether adding the new data record to the data set will result in a threshold for control area splits to be exceeded. In response to determining that adding the new data record to the data set will result in the threshold for control area splits to be exceeded, creating at least two new control areas in addition to continuing to use one existing control area for storing the data set.

Abstract: A method for data recovery of a data set migrated from a first storage media to a second storage media, where the data set includes a header record and multiple control records interleaved with corresponding data blocks. The header record is examined to identify a number of control records and data blocks comprising the data set. Next, the control records and data blocks are examined in order, starting with an initial data block, until a first data block is identified due to its failure to match the attribute included in the associated control record. Then the control records and data blocks are examined in reverse order, starting with a last data block, until a second data block is identified due to its failure to match an attribute included in the associated control record. Lastly, each data block from the first data block to the second data block are set to a lost data value.
