Hi Tommy,
For #2- A very large potion of our tapes are kept for 30 days or less. So, for cutover, the BusTech joined the same SMS pool and esoteric pool as the ATL/VTS it was replacing and the ATL/VTS was quiesced. All new allocations went to the BusTech. After a few weeks most of the migration took care of itself.

Tape still have life time, if 1TB tape damage then we need more time to re-built or re-create it, except you implement dual copy or PPRC VTS and it cost you more. 2. Tape migration is my concern, I think disk to disk migration is more faster solution. I can't find any migration approach for B20 to TS7740 or TS7740 to another new model, except using COPYCAT or TAPECOPY utility, read all tapes to cache and copy back to other tape subsystem 3. IBM Tape drives cannot read each other, TS1120, TS1130, TS1140...If a new model comes and we need to preform another migration....copy again and again from tape to another tape system because of new drives.....TRUE ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
