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: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
