Re: Exabyte Mammoth-2

Try looking at other st0 devices, like st0m, etc. On most OSes, the
different devices drives in /dev denote different options. On my system, for
example, md0 also points to /dev/st0. Check the magic numbers. Mine all
start with 9,  and st0 is 9,   0  ... You can see those by doing ls -la st0
and they are just left of the date.

In other words, experiment and see what you can find.

Hello,

How do I enable compression for this tape drive? I have a Exabyte Mammoth-2
tape drive using Exabyte 225m AME tapes.  I have looked around the Internet
searching for information on how to do this, but I can only find information
saying that it's compatible and it works with Linux.

I am using a standard "tar" command to write the data to tape, until
recently it has not been a problem as we never had enough data to fill up
the tape.  But now we do and I cannot figure out how to enable compression,
does anyone else have this tape drive and are able to get compression
working???

When I issue the command "mt -f /dev/st0 status" I get the following
message...

SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x28 (unknown to this mt).
Soft error count since last status=0
General status bits on (41010000):
 BOT ONLINE IM_REP_EN



I am running the following...

RedHat v6.2 on a Compaq Proliant with 120GB of diskspace.  Running kernel
version 2.2.14-5 SMP with 256mb of memory.



Thanks in advance.
