Hi,

I posted this message sometime back but not sure if it really
went thru. So, I will repost.

I plan to use amanda as my backup system on the above hardware and
OS combination. I am hoping to benefit from the amanda users group.

We have a Quantum DLT 4000 SCSI-2 tape device connected to a
RedHat Linux 7.1 box using BusLogic BT-950 card.

When the system boots, we get the following messages on the
screen:

        Vendor: HP Model: C5173-4000 Media Changer Rev: 3.02
        Vendor: Quantum Model: DLT4000 Rev: CD3C

The /var/log/messages file shows the following message:

        st0: Block limits 1-16777215 bytes.

When I use the mtx utility on /dev/sg0, things are OK. I am
able to do 'inquiry', 'status', 'load', 'unload' operations
properly.

I put a tape cartridge into the drive by using the command

        mtx -f /dev/sg0 load 1

Then I use the mt command as below:

        mt -f /dev/st0 status

        the output is:

        SCSI 2 tape drive:

        File number = 0, block number=0, partition=0
        Tape block size 0 bytes, Density code 0x1a
                                (unknown to this mt)
        Soft error count since last status=0
        General status bits on (41010000):
                BOT ONLINE IM_REP_EN

I am using HP 1/2" DLTtape IV Data cartridge.

When I try to do a tar onto the tape, I get the message:

        Wrote only 0 of 10240 bytes
        Error is not recoverable: exiting now

The HP DLTtape IV cartridges are recommended for this drive.
I thought there may something wrong with the particular
cartridge and so I even tried brand new cartridges. The
results are the same every time.

Can someone please help me understand the problem here ?

Thanks for your time.
