Re: How to erase TS7740 data before scrap
The IBM TS7740 is a virtual tape library. 1. How about DFSMSrmm EDGINERS ERASE? Other media managers, e.g. CA 1, have analogous functions. 2. If you have DITTO/ESA, there's an ERT (Erase Tape) feature that might work. 3. You could completely refill the virtual tapes with new "data." Maybe an endless repeating string containing your favorite poem? 4. There are some vendor products available, e.g. Dino-Software's XTINCT and Innovation Data Processing's FATS/ERASE. Although please check with them to make sure they can handle *virtualized* tape properly. 5. Supervised physical destruction and degaussing (of the disks) works. However, this option is inconsistent with claiming all of your TS7740's residual value. 6. Some combination of the above -- which would be prudent, I think, just in case one of the methods didn't correctly and completely work. And when you perform these tasks I'd do it from a system (LPAR) that doesn't have access to any real data, and with the TS7740 completely removed from other z/OS instances. From a "sysprog" LPAR, for example. I wouldn't try to do this from a "production" LPAR, out of an abundance of caution. Also, please be sure you aren't erasing your only copy of data that you still want to keep! :-) Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA E-Mail: sipp...@sg.ibm.com -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Mike, I think it depends on ICKDSF and which command is used to format the volume. Its been 20 or 30 years since the 3380 came out but IMSM the fast initialize does it differently than the full initialize. My memory is sketchy here but I *THINK* a EOF is written on each track if a fast init is used. I will defer to you on the full init. I learned of the fast init from a good friend at the WSC. I started using it and never had awn issue.

Re: How to erase TS7740 data before scrap
How are tracks provisioned? If fixed provisioning, then ICKDSF TRKFMT CYL(0,14) CYCLES(1) will write b'', b'', and b'01010101' or b'10101010' for the full track for three erasing writes to each track. Increase 1 for more erases. Erase all tracks in all cylinders of all volumes. If dynamic provisioning, then erase all volumes with extra erases to catch the excess capacity above the capacity of the volumes.

How to erase TS7740 data before scrap
We are replacing IBM TS7740 with new TS7760 and need to do a Cluster Cleanup (FC 4017 This feature is a factory default button, clear all data, all tables, etc..). IBM says that this feature is withdrawn and no more available. What can we use in place of it or any suggestion about how to clear data from it?
