Hi people, Is anybody using DLT tapes with Suse 9.2? Are you having any problem? My kernel is 2.6.8-24.16, my DLT 7000, my scsi card qla1280 and aha1960 (with both scsi cards I got the same behavior). The problem is: I can do "tar -cvf /dev/nst0 ..." with small files (50Mb) without problems, for big files the "tar -c .." work fine only if I defined a bigger block. Then the problem is after writing (for example a file of 700MB): "mt -f /dev/nst0 eod" : results in /dev/nst0: input/output error "mt -f /dev/nst0 fsf 1": results in /dev/nst0: input/output error or if I'm at eod and I do a rewind I got the same result The syslog tells: ".....resetting scsi bus .... st0: Error 40000 (sugg. bt 0x0, driver bt 0x0, host bt 0x4)" Just to test, I installed mt-st.07-421, I define the /etc/stinit.def following Quantum Manual but I got the same errors. Anybody has any idea? Regards. Mariela

I use a LTO-1 tape drive with the 29160 controller. I think I had it working with 9.2 and the stinit.def package, but I'm not positive. I'm now running 10.0 and my drive is NOT usable with the SUSE kernel. I have replaced the kernel with the vanilla 2.6.14 kernel from kernel.org. It is working fine. I believe that 2.6.14 contained some scsi/tape related fixes that are not yet in the SUSE kernels. With 10.0 SUSE kernel I was getting errors like "Failure writing End of Media".

I have an external Quantum DLT7000 which I normally use to backup my windows workstation. Just for fun I started an older server with an Adaptec 2940UW controller that I could use to connect the DLT. In short: it works without any problems.

I had those errors when I connected the DLT to U160 compatible adapters. It just wouldn't run reliably when connected to an Adaptec 29160N. Then I found out that it was NOT an LVD compatible, it was a single-sided and very happy with UW-SCSI.
Just to test, I installed mt-st.07-421, I define the /etc/stinit.def following Quantum Manual but I got the same errors.

Try a different controller and maybe another terminator. If possible you could try the external connector of your Adaptec controller, it should only be UW-SCSI, not LVD. That would probably reduce the bus speed to ultra scsi. Sandy -- List replies only please! Please address PMs to: news-reply2 (@) japantest (.) homelinux (.) com

I think it isn't the hardware because I got the same errors with: 1) AHA19160 Ultra SCSI SE HVD, DLT 7000 SUN SE HVD Fast SCSI. 2) QLA1280 automatically autosets for the drive connected, Quantum DLT 7000 Fast SCSI Diff HVD And I used on Irix that QLA1280 with that DLT without problems. But I'm a litle new with linux, so I'm not sure if the problem is the st module, mt or what. Mariela

If you are using the same controller with the same DLT drive then it should work. Do you perhaps have any other scsi devices on that controller? Here's the /etc/stinit.def, that I used: /etc/stinit.def: #-------------------------------- manufacturer="QUANTUM" model = "DLT7000" { scsi2logical=1 can-bsr auto-lock=0 two-fms=0 drive-buffering=1 buffer-writes read-ahead=1 async-writes=1 can-partitions=0 fast-mteom=1 # # If your stinit supports the timeouts: timeout=3600 # 1 hour long-timeout=14400 # 4 hours # # Drive is backwards compatible, use older modes (e.g. from above) as required. # mode1 blocksize=0 density=0x85 # 35GB + compression mode2 blocksize=0 density=0x84 # 35GB, no compression mode3 blocksize=0 density=0x83 # 20GB + compression (DLT4000 mode) mode4 blocksize=0 density=0x82 # 20GB, no compression (DLT4000 mode) } #-------------------------------- Sandy -- List replies only please!
