I have two iSeries machines both running v6r1. One is our production box (Model - E4A w/internal tape drive) and the other is a cold backup (Model 520 with external Transberg 3503-lto 4 tape drive). I am trying to restore libraries from our production box to the backup. I can browse the the tape data on the old machine and see the libraries on there but when i try a rstlib I get the following error:
"device tap01 used for save or restore is damaged"
I can save library's from the backup machine to the external tape drive and restore them back to that same machine with no issue. Could the tape drives be using a different writing method/compression/block size?
