SCSI not showing Quantum LTO2 / Adaptec 1480 anymore

I have a brand new Quantum LTO2 HH drive and it won't show on the SCSI bus anymore. Initially it showed for the first couple of days, but it no longer recognizes it. However, if I first plug in a Sony SDT-11000 drive it recognizes, then if I pull the SCSI cable out of the Sony, and plug it into the Quantum drive, it recognizes it (Adaptec SCSI Explorer shows CERTANCE ULTRIUM 2 Revision 1823), and cygwin mt -f /dev/nst0 status shows the drive online. And it writes/reads fine. I tried swapping connectors and such, but to no avail. My equipment list: one Adaptec 1480A, two Adaptec 1460A, two 50 pin cables, two 50-68 converters, two SCSI terminators, Sony SDT 11000 DDS4 drive, Quantum LTO2 HH drive, Toshiba U200 XP/Home. Weird huh ? Any suggestions.

It shows 3 ATAPI devices for the disk drive now plus the Adaptec card, before it showed only the Adaptec Card. I'll try plugging in the Quantum the next chance I get. Will post my results soon...

Ii just tried the Radified ForceASPI 1.7 and ForceASPI 1.8. No luck. Same thing. The Quantum does not recognize. As before, to get it to recognize, II have to 1st plug in the Sony SDT-11000 drive, and then plug in the Quantum LTO2HH. The Adaptec 1480A, 1460D, 1460A are pretty old. Maybe the firmware is so old it is incompatible with newer tape drives ? I guess the next step is to try a late model Adaptec PCI-X or PCI SCSI card. I don't own a desktop anymore and would have to buy one. Maybe I should go that route ? Also, I have access to a Compaq notebook with an ExpressCard slot. I surfed around and don't see any SCSI cards available in the ExpressCard form factor ?

This sounds like a SCSI address problem to me. These kind of issues always come up due to address mixups or termination issues.

Some progress... the drive hookups and tests fine using Quantum's winpuke programs. Quantum's DFU.exe (download firmware) detects the Quantum LTO2 HH after I hookup everything and cycle the power on the drive. TapeRx.exe (tape diagnostics) passed all the tests I ran. However, Cygwin mt and TapeSnoop 1.2 still does not recognize the drive. I tried cycling power, re-inserting and swapping Adaptec 1480A/1460D/1460A cards, cables, terninators, etc. As before, I can still get Cygwin mt to recognize it if I 1st hookup the Sony drive. Next step is a) buy an Adaptec USB2XChange and try it, b) buy another S-ATA drive, install ubuntu, and try it. > This sounds like a SCSI address problem to me.

Something is wrong in the recognition/negotiation process of the Quantum drive that you are trying to ignore by finding fault in the adapters. They are all working fine with the Sony. Every indication points to the Quantum as the problem, stop ignoring that.

One reason for not being detected could be that the drive takes too long to come on-line on the SCSI bus after a reset. It may not respond to SCSI commands yet when the SCSI bus is scanned. You could try setting the drive at ID 6, to make it the last device address to be scanned. This allows another 1.5 second for the drive to become responsive. Also, is there any difference between a cold boot and a warm restart of your system? Rob

So there is something in the setup process during the bios stage (in any bios) that this drive doesn't like anymore. Apparently drivers do the initialization just a little bit different and then it works. Maybe they don't even negotiate speed at all and it works just async. In the old days some SCSI peripherals negotiated themselves in dangerous territory depending on what SCSI contoller they were and you could limit the speed range that they were allowed to negotiate. Usually you can still do this in the SCSI adapters bios. I would experiment with that and see if that makes any difference in the drive's behaviour (providing then that your adapters have that feature).

I'm sorry I'm quite out of words right now. I suggest that you make an effort and read the above paragraph once again. > i may buy a scsi card from ratoc and try it. Yes, why don't you do that. You seem intend on ignoring any advice given to you anyway.

With the PCMCIA/Cardbus adapters not having a bios -as it turns out- it follows that the driver is doing the initialization and this isn't working as supposed to anymore. Supposedly it makes the Quantum go play hide and seek. > > > > Maybe they don't even negotiate speed at all and it works just async. That would be the situation when you cycle the power on the Quantum and it comes back up in Async mode. What transfer speed does the Quantum make once you get it recognized and working. If around 5MB/s or so this would indicate it working in Async mode. If alot more, this would indicate some sort of renegotiation between driver and drive and that would be puzzling to why that would work and normal driver initialization would not. > > > > > > > > In the old days some SCSI peripherals negotiated themselves in dangerous > > > > territory depending on what SCSI contoller they were and you could limit > > > > the speed range that they were allowed to negotiate. > > > > Usually you can still do this in the SCSI adapters bios. > > > > I would experiment with that and see if that makes any difference in the > > > > drive's behaviour (providing then that your adapters have that feature). With 'normal' SCSI controllers you can still choose modes in the driver tab of a SCSI device in device manager. Choice is async vs sync mode. See if there is a similar choice for the cardbus adapter connected devices. > > > > > do you mean the 'bios' in the notebook (Toshiba Satellite U200) or the > > > firmware in the Adaptec 1480A/1460D/1460A ? > > > > I'm sorry I'm quite out of words right now. > > I suggest that you make an effort and read the above paragraph once again. > > > > > i may buy a scsi card from ratoc and try it. > > > > Yes, why don't you do that. > > You seem intend on ignoring any advice given to you anyway. > your advice is appreciated but none of the adaptec cards i have now > have an accessible bios. And so it appears. The documentation is unhelpful to not available for these things.
