SCO 5.07 and Tape Drive

[EC]

Hi all,

I have a Dell server with onboard duo-channel SCSI/RAID adapter. I
am trying to connect an external tape drive (Dell PowerVault 100T)to
this machine. What I did was I put an Adaptec 2940U2W adapter on one
of the PCI slot and connected the tape drive to this Adaptec card.
Here is my question. When I ran "mkdev tape", what should I enter for
my SCSI host adapter/SCSI Bus?

This is the result I got when I did "sconf -v": Stp blad 0 0 2 0

Thanks.

No it doesn't. That's what mkdev tape is for.

How many tape devices are configured on this machine? Try posting the
output from 'hwconfig -h' and the contents of your
/etc/conf/cf.d/mscsi file. Also, ls -l /dev/rSt*.

And recall that the parameters you used when you ran mkdev hd are
configured into the kernel. But if the device is not actually connected
to bus 0 of the 0th blad adapter, or its ID is not really set to 2, then
Unix will of course find nothing there.

The values you use in mkdev tape must reflect the actual hardware
configuration.

Yep, a good point that I *should* have thought to include in my last
response. Thanks JP.

I have a Adaptec SCSI card (2940U2W) and an onboard SCSI/RAID
controller. The external tape drive connects to the Adaptec card and
it's set to SCSI ID 2.

MSCSI shows:
lsil Dsk 0 0 0 0
wd Srom 1 0 0 0
blad Stp 0 2 0 0


Hwconfig shows:

Thanks again for your help.

Everything here seems to be OK - Your mscsi file reflects what you
have told us, as does the output from hwconfig.

Now some obvious questions:

Was there a tape in the drive when you issued the above commands?
Have you tried other tapes?
Does this drive work on other systems?
What type of termination/cable are you using?
Is the PowerVault (IIRC from the initial post) an auto-loader by any
chance?

I'm at a loss at this point.

The tape command defaults to the xct0 as I recall and normally that
is linke to the /dev/Stp0 [spelling].

The tape command will also take a device name as an argument.
Given the proper device name I've had 'tape' always work, but
not always if you use the default.

Is that really true??? "Dsk" is an alternate SCSI disk peripheral
driver designed to be used only with the Tricord "iiop" HBA driver.
Does your mscsi file _really_ have "Dsk" rather than "Sdsk"?

Please show the hwconfig lines relevant to the disk.

This is a side-issue probably unrelated to your tape drive problem.
It's just that I've never seen the "Dsk" driver in use (on _anything_,
never having actually touched one of those Tricord systems). It has not
been well maintained over the years, I would worry greatly about using
it.
