Use automatic or integrated cartridge loaders (ACLs or ICLs) to reduce cartridge mount time for multivolume, for example DFSMShsm migration level 2 and backup volumes, and scratch mounts. Typically, scratch mounts represent about 60% to 80% of all tape mounts. Directing these mounts to devices with ACLs or ICLs can significantly reduce mount times, compared to operator performed mounts.
