Subject description: I need to know how to install the drivers now that the tape is on a SCSI
 

I have the tape drive on an Adaptec SCSI card and I would like to install the drivers for Fatdog 710 Linux.

I've never installed a tape drive before nor any other SCSI device.

I keep reading manuals and I just haven't found one yet. I think I'm getting warm though as I've seen some websites of IBM's.

I'll keep trying, but if anyone knows how to get the drivers and/or install the drivers for my Fatdog please let me know.

It's an 23R4762/95P2012 drive. These were made between about 2006 and 2008. I am looking at the documentation but I'm still clueless. Something detects the thing on boot up. Everything seems ok so far.

Perhaps this has the drivers - and i need to install them for the Adaptec card and then later for the IBM drive? I thought Linux would just detect the card and install the drivers.

I believe there are projects where people have attempted this. Perhaps I can just compile their drivers source.

I guess somehow I need to get these drivers noticeable? Perhaps when it says Ctrl-A to set up I need to set up the SCSI card with a bunch of parameters.

But I think that's ok.

I'll check for drivers now. Perhaps my Fatdog does not yet have them. I might need to build them so that the kernel picks them uip on boot.

But when I try to see the files. they are not there. Strange?

So my next step is to try to build the drivers.

I hope I have the right kernel

Wow, I wish I knew how to set these cards up.

PostPosted: Fri 26 May 2017, 21:13    Post subject: The output of the lspci command
Subject description: I just ran lspci
 

The output of this command DOES in fact list a controller by Adaptec:

02:00.0 SCSI storage controller: Adaptec AHA-3960D / AIC-7899A U160/m (rev 01)
02:00.1 SCSI storage controller: Adaptec AHA-3960D / AIC-7899A U160/m (rev 01)

So I will now conclude that the Adaptec IS in fact installled.

I need to now search for a tape drive's drivers.

Subject description: I don't know why they aren't picking it up.
 

When I run the dmesg command, I don't see an IBM tape drive - and no /dev/stx devices. I think my only choice of drivers unless I have source code is to use Native Linux. I guess I should find out where these drivers are supposed to be.

Under dev/scsi/dev???_info I do see the IBM tape drive listed. At least one little part of the OS sees a tape drive of some sort. Or perhaps it simply is that it uses that long list of devices and found what it thinks is a match. This is confusing. I guess I thought it simply added that string to that device file - I think this is what happened.

I have not yet installed sq utils on the test machine. They wouldn't work anyway. I need to get the computer to recognize the IBM drive and load some drivers and attach them to the device.

sorry PappyPuppy, just came across this one.

So you can see the adaptic card!

And you can see the Tape drive on the scsi bus!

And it has a bus address as ??? (should be seen if doing a full bios startup routine) and it's not 0 or 7 or 15!

And if you look in /dev there is a suitable block device https://www.cyberciti.biz/faq/tape-drives-naming-convention-under-linux/ ? You may have to make this with mknod. Also see the last line on the webpage and go there, it's important to understand before you play.

Does your kernel have the internal links to deal with a Tape Drive? Ask the puppy system's maintainer (in the correct thread).

Is there a blank tape in the drive and it's the correct type (very important as a lot look the same but are different). This Just makes it easier to deal with at this stage.

And that's just to start with. It's not hard, just a lot of reading and a bit of setting up for a new user.

I'll keep an eye on the thread in case you need further help. Back when Puppy 3 was very new I had a complete Dialup BBS system running on Tape drives except for a (small by nowadays standard) 5Meg Hard Drive for the system and it's controls and logs.

And I go back to pdp8's and IBM Front End processors that were all connected via scsi, i've even got a 8" Floppy Drive that's SCSI.

Thus is why my 'tag' was given to me in the early '70's.

Subject description: I DO NOT YET HAVE A BLOCK DEVICE as in st or something
 

I am so dead tired from my hardware setup alone as I had to scrounge around box after box to find a power stub extender.

Anyway, I know that there are two ways to "drive" the IBM LTO Ultrium - one is by Linux's own kernel drivers, and the other is by the IBM-specific.

It will take me many hours to check each of the concepts that you just suggested. I'm guessing that the SCSI card is running on ID 7 which is the default, and it sees the IBM drive as you mentioned. What I would love as my next step is to NOT see the Adaptec BIOS program SCSISelect run each time I boot. I've changed and/or just accepted the parameters. It should not keep running each time. Yes, I need to keep reading and studying. And I keep downloading manuals and hope that they are the right vintage - even the wrong vintage will help though as the concepts are similar. It's a lot of reading for me.

I'll post my next step or discovery and keep someone watching. This is tiring work for me as I'm not a Linux guru. But at least I got my Fatdog going on yet another machine. So I now have two fatdog machines and a fatdog laptop. They are all still running but the one I have the IBM tape drive on has a slight hardware problem. But right now it's running ok so I can use it. I can live with that slight problem. It will not interfere with my getting this IBM tape drive to work.

PostPosted: Sat 27 May 2017, 08:22    Post subject: Here's some information
Subject description: A list of info
 

1) I have not yet put a tape in the drive. I don't want to do that until I have a device. There's no point in putting a tape in - there is no st0 device yet. The device will obviously be called st0 and will appear as an icon once I get some drivers going.

2) I left the jumper on the IBM Ultrium on the left-most position looking from the rear of the drive. I'm confused - I don't actually understand - are there two jumper sets - one for TERMPOWER and one for ID? I am very confused about that.

3) My maintainer is for Fatdog - I would have to ask them. But I should be able to browse and find a driver. I need to know what the names of the drivers are.
