For this case study, we used the DASD Multiple Volume Analysis Report to analyze 16 volume serial numbers for mapping on eight dual density devices. The volume serial numbers were PACK01, PACK02, PACK03, XXXACC, XXXACT, BSDIS1, BSDIS3, BSDIS4, BSDL03, BSDS01, BSDS02, BSDS05, BSDS06, BSDL05, FERC01, and BSDIS4. The time period was from 7:00 a.m. to 6:00 p.m. each day for the past three days. The CA MICS database containing the installation's hardware data was denoted by database identifier B. The inquiry fields for the study are shown in Figures 2-120 and 2-121.
