I'm having troubles compressing a DDS-4 tape. I have an HP C5683A drive,
and when I do 'mt -f /dev/nst0 status' (or mtst) I get:
twist:/opt/ltt # mtst -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x8c (EXB-8505 compressed).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN
The problem is that it's not using compression, although it's turned on.
My questions are:
- Is EXB-8505 the right compression mode? I read you could change it to
DDS-4, but what's the compression code for DDS-4?
- Do I need a hardware specific driver for the SCSI controller for the
O.S. to recognize the tape in the proper way?
- Something I'm missing?
Thanks in advance,
