Abstract
Various embodiments are provided for saving a log data in a hierarchical storage management system using a disk system as a primary cache with a tape library as a secondary cache. The user data is stored in the primary cache and written into the secondary cache at a subsequent period of time. Blank tapes in the secondary cache are prepared for storing the user data and the log data, based on priorities. At least one of the blank tapes is selected for copying the log data and the user data from the primary cache to the secondary cache based on priorities. The log data is stored in the primary cache.
