Add new SCSI tape for backing up all files systems

Hi
I Plugged in a TZ87 drive in alpha1000 v4.0
The tape is seen from >>> level as DKA400
and also seen from Os level as follow
Bus 0 target 4 lun 0
I did
cd /dev
./MAKEDEV tz4
But still can't use the mount or mt command

Any advise will very welcome.

Regards,

Fodil.

Hi,

MAKEDEV counts. First rmt0 then rmt1 and so on.
Please remove all rmt devices in /dev and try again.

greetings,

Michael

Re: Add new SCSI tape for backing up all files systems

At the console level (>>>) I believe tape drives are named MKA###. Are you sure you're looking at the correct device?

If you use >>> show device, what does it say to the right of the device name?

Re: Add new SCSI tape for backing up all files systems


And if by any change your confused about your OS version.... on V5.xy, you should use

hwmgr scan scsi
and
dn_setup -install_tape

(as said before, at the console >>> it should appear as MKxn00 not DKxn00...)

Hi Michael and Vic, thank for your kind quick answer. I did this

Answer For Vic, The >>> prompt see the DKA400 as RRD43 DEVICE. and as you see the OS see it also as RRD43

Then I still get the problem.

Re: Add new SCSI tape for backing up all files systems

RRD43 is a Compact Disk (CD) drive. It's definitely not the tape drive. Sounds like your system doesn't see the tape drive at all.

Could you shut it down and show us the output from >>> show device?

Re: Add new SCSI tape for backing up all files systems

You're probably right, I might badly interpret what I have seen.
In /usr/adm/messages the tape is seen as TLZ09 target 1 lun 0

This device is not seen in scu below.

Re: Add new SCSI tape for backing up all files systems

Those are old entries in /var/adm/messages, they go back to July. You just added this tape drive, right?

Again, you'll have to shut down and do >>> show device.

Re: Add new SCSI tape for backing up all files systems

1) Check the cabling and make sure it's correct.

2) I assume this is a table-top TZ87. We no longer have TZ87s so I can't say for sure. Look at the back of the tape drive and you may see a switch for the SCSI ID. On the tape drives we do have it is set to 6.

3) Turn the power off & then back on, 1st the tape drive and then the Alpha.

4) At the >>> prompt 'init' and then do a 'show device' again. See if the MKxn00 shows up.

Re: Add new SCSI tape for backing up all files systems

The tz87 I wanted to plug in the tower
seems to be incompatible.

The tabletop TZ works fine, immediatly.

Thank's to all.

Fodil.
