I originally interpreted the question as 'how to replace (all) tape with 3390 DASD?'. VTS is a worthy choice to eliminate traditional tape as we all know and (maybe) love it. Behind the virtual tape drives--actually server disk emulation as already mentioned--are a set of 'real tape drives' that provide permanent and low(er) cost media for data used infrequently or maybe even never but must nevertheless be retained indefinitely.
Starting with VTS from the ground up is a big deal. First off you have to decide on a vendor, which is no trivial feat. Implementing is a fairly major project, although end users should be lightly affected if at all. In other words, you want to have VTS in place and functioning comfortably well before you redirect HSM migration. . .

I was told by our DASD vendor that HSM is architected to use tape for backup, and using disk can be harder to manage. To implement a VTS would mean a simple recycle to get the 'real tape' backups to virtual tape, but I would still prefer to get the VTS on the floor a few months ahead if we can and let the tape backups fall off the end, then recycle what is left. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
