The AUTOCHANGER class contains an array list of tape + devices. When a tape drive is needed, this list is always searched in + order. This causes lower number drives (specifically drive 0) to do a + majority of the work with higher numbered drives possibly never being + used. When a drive in an autochanger is reserved for use, its entry should + be moved to the end of the list; this would give a rough LRU drive + selection. + +Why: The current implementation places a majority of use and wear on drive + 0 of a multi-drive autochanger. + +Notes: + ========= New items after last vote ==================== -- 2.39.5
