Depends upon which type of DASD you have. If you're using a SAN, use the SAN's manager tools to reformat the DASD, 3 passes will do. Or, you can have IBM come in and scrub it for you. Your regular customer engineer can perform the reformatting at the SAN level for you. If you truly require DoD-level cleansing and a certificate stating as such, another division of IBM can come in and do that for you I can send you the particulars off-list if you want them. It is expensive.

Carrier Sent: Wednesday, April 14, 2010 8:40 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Scrubbing DASD Hi Folks, Haven't been on here in a while. I have missed you guys ;) MIT will finally be shutting down it's zVM systems that have been running remotely at Blue Hill Data's datecenter for the past couple of years. I am looking into what I'll need to do to do a reasonably thorough DASD scrubbing, thorough enough to satisfy the new privacy regulations, etc. I assume I'll be using ICKDSF to do the dirty work, and am looking for suggestions for which commands, how many passes, etc. to do. Thanks in advance! Peter
