We made the move from VTL to DD VTL by moving the tapes in order of oldest to newest. The theory being that all of those notepad copies that are 5 years old could be on the same tape and it should reduce reclaims. Out of curiosity, how big are you making you files on the DD?

The DD will be used as a NAS device via a file type pool. Currently, there is the normal DISK->TAPE hierarchy of primary pools with the need to get to DISK->DD. 1) use movedata chg DISK nextpool to DD chg DD nextpool to TAPE movedata from TAPE to DD current: DISK->TAPE transition: DISK->DD->TAPE movedata TAPE back to DD to clear out old pool final: DISK->DD We control the movedata process with scripts. 2) use migration chg DISK nextpool to DD chg TAPE nextpool to DD migration from TAPE to DD current: DISK->TAPE transition: DISK->DD<-TAPE migrate TAPE to DD to clear out old pool final: DISK->DD Migration runs process automatically. 3) Other ??????? Are they any other ways do this? ----------------------------------------- The information contained in this message is intended only for the personal and confidential use of the recipient(s) named above.
