The definition of "...nothing is recoverable..." is in the eye of the beholder and the beholder's regulators. I think PCI requires complete physical destruction (as in shredded, not just smashed or drilled).
Your use of the term 'surplused' would imply some governmental context, and that may push you closer to a physical destruction scenario. Good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Linda Mooney Sent: Tuesday, June 30, 2009 6:36 PM To: IBM-MAIN@bama.ua.edu Subject: ERASEDATA - DASD disposal Greetings! I am in the process of retiring 3 RAMAC 2 racks, each with a 3990 mod 6 controller, and 1 RAMAC 3 rack, with a 9293 controller. All data has been moved to new DASD. The RAMAC DASD will be surplused so I have to be sure that the data has been wiped clean and nothing is recoverable - w ithout physically damaging the devices. All of the DASD is 3390-3. For the RAMAC2 data wipe I have been using ICKDSF release 17.0 TRKFMT UNITADDRESS(B40) VERIFY(ZSDLZ6) ERASEDATA - CYLRANGE(0,5000) CYCLES(4) That takes about 20 minutes per cycle. Our maintenance vendor recommended 4 cycles. That seems to be proceeding fine. I am having a problem with the RAMAC 3. I tried the same coding with the RAMAC 3 and it took about 5 hours to run (per address) as compared to roughly 1 hour 20 minutes on the RAMAC 2 . All devices are 3390-3, each controller has 4 paths, low system activity generally with no other work on these strings, and the long run time was consistent for several packs on the RAMAC 3. Should I use some other ICKDSF command to wipe the RAMAC3? Any t houghts on why the run time would be so mu ch longer for the RAMAC3? Do you consider the 4 passes with TRKFMT enough to be sure that the data is really gone?
