Rather than appending to an old thread you really ought to start a new one so it gets higher visibility. Often the only people that see an old thread (if any) are the ones that previously responded to it.

OK
Thanks

As some of you suggested the problem was solved by installing the same microcode levels and same part number tape drives on both machines. Basicaly level III Tape drives. Even though the FRU numbers are the same they also needed to be the same part numbers with same microcode level.
