20/40 DLT tape drive

I recently installed a tape drive on my server, only to find no Linux support was available for it. I am unable to find appropriate fstab and mount commands for this device. Does anyone have this information?

Re: 20/40 DLT tape drive

It should be something like /dev/st0 ...
sample from my dmesg:
Detected scsi tape st0 at scsi2, channel 0, id 4, lun 0
sym53c875-2-<4,*>: FAST-10 SCSI 10.0 MB/s (100 ns, offset 16)
Vendor: HP Model: C1557A Rev: U709
Type: Medium Changer ANSI SCSI revision: 02
....
There's a command called mtx which allow you to access the device and change between tapes. You can get it at -> http://mtx.sourceforge.net/

Re: 20/40 DLT tape drive

I'm trying to do what "wankdc" apparently has done. Attach a HP SureStore to the imbedded SCSI Controller on my Proliant 5500. I'm running RedHat 6.2, and trying to build a new kernel (2.2.18) and the box deals with the RAID array attached to the SmartArray just fine. however, I get :

Jan 25 15:24:24 bigboy kernel: scsi : 0 hosts.
Jan 25 15:24:24 bigboy kernel: scsi : detected total.

at boot time when it tries to access the imbedded controller, and
by extension the Tape Jukebox. Of course this controller worked
just fine when I ran WinNT on the box...

Kevin, could you elaborate any further on the kernel/configs?

Thanks in Advance!

Lyle,

Did you compile in low-level SCSI drivers?
#
# SCSI low-level drivers

CONFIG_SCSI_NCR53C8XX=y

Re: 20/40 DLT tape drive

Kevin/all -

Was trying to follow the instructions in Gerhard Mourani's "Securing and Optimizing
Linux: RedHat Edition" and installing a monolithic kernel from 2.2.18 sources
at www.kernelnotes.org with the secure linux patches from
www.openwall.com/linux. Adding lines in the /usr/src/linux/.config file for
the SYM53C8XX support were ignored due to the fact that they HAVE to be
loaded as modules. Once I did that, SUCCESS!

From the messages file - for posterity:
