Hey folks,
Linux admin here, forced to use Opensolaris to try to use ufsdump/ufsrestore to get some data of some old tapes.
I've got Opensolaris 2009.06 on x86 and a Sony SDX-700V.
As a "control" experiment, I booted the system with a Linux live CD and the tape drive worked perfectly.

Description
The SCSI tape driver provides a standard tape drive interface as described in This is a driver for any Digital SCSI tape device.
For the TZK10 QIC format tape drive, the densities supported are QIC-24 (read only) block size of 512 byte blocks, QIC-120, and QIC-150
read/write block size of 512 byte blocks, and QIC-320 read/write block size of 1024 byte blocks. With QIC format style tapes all reads and
writes must be in multiple of the block size. This is a requirement of fixed block tape drives because record boundaries are not pre-
served. The QIC densities are selected using the following special device names:
QIC-24 Fixed block size.
QIC-120 Fixed block size.
QIC-150 Fixed block size.
QIC-320 Fixed block size.
With all fixed block tape devices a of a file to the tape must be padded out. An example of this is a of which has a size of approximately
3800 bytes.
dd if=/etc/gettytab of=/dev/rmt0h bs=10k conv=sync
or
dd if=/etc/gettytab of=/dev/rmt0l bs=512 conv=sync
The option of pads the output to block size.
This driver also supports n-buffered reads and writes to the raw tape interface (used with streaming tape drives). See for further
details.
