Hi Don, The concern is that the 3590 tape drives are soon to be end of life, January 31, 2015 to be exact. IBM's externally available documentation says the 3590 H1x drives will be supported until October 2015, but our CE's manager told us that is incorrect, and All the 3590s fall off support end of January. We can't get extended support for the tape drives apparently due to IBM's inability to get spare parts, so mgmt is looking to see if we can restore the data from the stack tapes back into the VTS cache on a stack-tape-by-stack tape basis in order to minimize the number of mounts and read/rewind cycles being performed. Our 3590s (both tapes and drives) are getting tired and we are trying to keep them going long enough to get off them. We've considered third party EOS support for the 3590s, but the concern there is the same as with IBM, are there spare parts available to keep them running?

As I recall we deployed our new TS7720 VTS and then ran appropriate jobs to copy the logical volumes from the old B10 to the new VTS. We never really concerned ourselves with the actual contents of the stack tapes. Just curious as to why wouldn't you simply let the VTS handle it? -- Donald Grinsell State of Montana 406-444-2983 [email protected] "There are but two powers in the world, the sword and the mind.

AFAIK, all it knows about are the virtual tapes in the B20, although I will admit I don't know much about CA1.
