I'm trying to import tapes created on AIX 5.2 running NBU 5.1 Phase 1 works; phase 2 gets failed media read errors. I can read tapes created on Windows and Solaris boxes so I know the standalone SDLT drive is working. Is there something special about how AIX writes to a tape that we need to account for? We've tried multiple tapes with the same results.
Here's the errors from the BPTM log:
