Bug Using the DD command to read an ISeries tape
An ultrium 2 tape was sent to our site to extract the data.
The problem is that they did not send instructions on how it was backed up, block size, etc.

Since then I found out that they used the DD command.
I tried running the following but it extracted only 3 lines worth of data.
It appears to be a header and trailer record.

dd if=/dev/rmt1 of=/tmp/tapedump.out
0+3 records in.
0+1 records out

I think there was a problem on their end in creating the tape but since I am not that familiar with the DD command I thought I would ask for any suggestions.
Any Suggestion on what syntax to use with the DD command ?

Thanks,
Brent Osuna
