SuSE L/390 SLES7 (31 bit) running under VM 2.4.0.
It appears to me that the non-rewinding tape device (ntibm0) is doing a rewind when it
should be leaving the tape in place.
As a basic test I'm doing the following operation:
mt -f /dev/ntibm0 rewind (position the tape at
beginning)
dd if=/test/test.1 of=/dev/ntibm0 (write out the file test.1 which
contains the line 'test file 1' )
dd if=/test/test.2 of=/dev/ntibm0 (write out the file test.2 which
contains the line 'test file 2')
dd if=/dev/ntibm0 (read in the contents of the
tape)
test file 2 (the tape contents)
0+1 records in
0+1 records out
If I do a rewind of the tape after writing the second file, and then do a read of the
tape I should see the contents of test.1, but rather see the contents of test.2 (at
the beginning of the tape.)
Is this a valid test for tape positioning?
Is there a problem with the tape390 driver?
TIA...Royce
