Hi Justin,
My scenario is slightly different in that I am duplicating to disk storage
first before writing to lto4. We tell bpduplicate to set the new copy to
primary. The problem I had was that copy one (source) went to copy 2
(disk) which went to copy 3 (lto4 tape). Copy 2 was expired by the DSSU
and rather than copy 3 become primary copy 1 was set again. I wanted to
check that if I expire the copy 1 tape, that copy 3 will become primary.
>From what you have said it seems like this is the case. I will have to
try and see what happens and see if any one else has any updates.
Regards
James
