SUMMARY : Restoring an AIX tar from EXB8500c

My problem was due to a very large blocking factor (b=1024) when
creating the tape. Seems this value is accepted on a RS6000, but not on
a Dunix machine.
Problem fixed by recreating a tape with a value of b equals to 2.

Thanks to all who provided assistance

The original message :

Trying to # tar -xvf /dev/nrmt0h an Exabyte tape (5 Gb compressed) that
was created on a Rs6000 machine (through Smith), I get the following
error :
tar: [offset 0] : No space left on device.

Have tried operations like : # mt rewind /dev/rmt0h
                                           # mt fsf /dev/nrmt0h (one or two times)
previously to the tar command, but no success

Have also tried # dd if=/dev/rmt0h
giving :
0+0 records in
0+0 records out

Does this definitly means that the tape is empty, or do I have to specify
additional flags to be able to read this tape, or is there a need for the
creator of the tape to include specific flags for it to be readable on a
Dunix system ?
