Hp Ultrium Driver Problem


Hi, I have a problem regarding setting up a tape drive. I have
consulted the supplier (HP) but they don't seem to understand the
issue.

I can use the tape drive, forward, rewind it, copy things to/from it
but it detects it as a 2GB instead of 200GB drive. I think the problem
is on the Density Code (0x40) that applies for a DLT1 drive, not for a
LTO one.

The specifications are as follow:

OS: SLES 9 (SuSe Linux Enterprise Server)
Kernel Ver.: 2.6.5-7.97
PC: Dell Power Edge 1800
SCSI Card: Adaptec AHA 2940W / 2940UW
SCSI Card Driver: AIC7xxx
Tape Drive: HP StorageWorks Ultrium 215 (internal)
Tape Drive Driver: mtst (provided by SLES 9)

In the dmesg I have the following entries:

scsi3 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 2940 Ultra SCSI adapter>
aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs

(scsi3:A:3): 20.000MB/s transfers (10.000MHz, offset 8, 16bit)
Vendor: HP Model: Ultrium 1-SCSI Rev: N26D
Type: Sequential-Access ANSI SCSI revision: 03

The "mtst -f /dev/nst0 status" command gives me the following message:

SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x40 (DLT1 40 GB, or Ultrium).
Soft error count since last status=0
General status bits on (1010000):
ONLINE IM_REP_EN

On hp's site, it says that this tape drive is fully compatible with
this Linux version, so the "mtst" driver should comply it:

hp.com/products1/storage/compatibility/tapebackup/software/index.html

Thank you in advance,
Daniel

I'm not familiar with Suse, but I know solaris has presented a similar problem when the drive description in st.conf is not present or correctly defined it will default to a generic driver. You might look for a man page on st.conf to see how this info should be formated or search HP's site for an appropriate st.conf entry.

Hope this helps.

Finally I discover that the open source backup software I was using was forcing to set the tape capacity, instead of quering the driver, so I change it and it works now.
Anyway, thank you very much for your answer.
Cheers,
Daniel
