Abstract:
A method for testing the sequential integrity of individual logical volumes organized in a sequential group of logical volumes in a magnetic disk storage system comprising the steps of:A) defining a dedicated storage area in each logical volume,B) defining a configuration file for storing configuration data for each logical volume that defines predetermined characteristics of each logical volume that includes a field that states whether a logical volume is in the group and additional data concerning first characteristics of the logical volume in that group,C) storing a unique signature in the dedicated storage area for each logical volume wherein the unique signature includes characteristics corresponding to the first characteristics, andD) analyzing, for a selected logical volume, the signature in the dedicated storage area and the first characteristics of the configuration data common to the dedicated storage area and the configuration file to confirm that the logical volume possesses all the first characteristics forth in the configuration file as a condition precedent for access to the data in the organized group of logical volumes.
