B1000 Workstation tape drive errors

[Nick D'Angelo]

All,
The external DAT drive has been a pain lately.
I have tried to remove the /dev/rmt/files and tried to iscan -fnC tape and mksf -e to recreate them etc, but no go.

The last thing I tried was mksf -d stape -I i -a -b BEST /rmt/0m and it came back with:

Couldn't find driver matching arguments.

Now what?

Try insf -e.

The command you are looking for is rmsf to get rid of them.

Then boot the box and they should recreate.

But first.

dmesg

check /var/adm/syslog/syslog.log

If there are lbolt errors associated with the SCSI ID of the tape drive, your drive, cabling, termination or scsi card could be a trouble.

[Nick D'Angelo]

Negative - insf -e did nothing and the rmsf removed the directory I specified and then i ran insf -e again and it did not create new device files.

[Nick D'Angelo]

Actually, the message desc is wrong. There are no errors reported at this time.

No messages no Lbolts in /var/adm/syslog/syslog.log

[Ross Zubritski]

Did you ioscan -F, then insf -e?

[Helen French]

what type of DAT drive? Is it listed under ioscan -fn as UNCLAIMED? Did you try using a different tape driver (tape2)? Are these drivers (stape, tape2) are included in the Kernel? Do you have the device connected properly?

[Nick D'Angelo]

Yes, I did the ioscan -F, first, then the insf -e and not stape devices created in /dev/rmt.

[Nick D'Angelo]

stage is in the /stand/system file.
tape2 is not.

[Ross Zubritski]

Does the "ioscan -funC tape" show anything, such as NO_HW?

Also, check termination, etc.

Steps,

1. Boot the workstation and interrupt the boot process.
2. Type "search " Press enter u should see a sequencial device ---->that is the tape and H/W is getting detected by the system

"if [ $? -ne 0 ];then exit 127;fi "

3. run sam --- > kenerl config--->drivers ---> locate "stape" in that and find out whether it is "in the kernel" / "out of the kernel"

"if [ OUT ] then;
make in from there and rebuid the kernel
fi"

If all these chekc points are clear then the tape drive should work.....

After making it in you may use insf / mksf to create device files ..............

Can you post ioscan -fn o/p ?.

Looks like it's a connectivity problem. First step should you take is to run 'ioscan -fn' and examine its output for unknown devices and devices having 'tape-like' inquiry string ("HP C1537A"). If you'll find this entry and check inquiry string and make sure that this is device you're looking for then machine sees this device and 'insf -e' should work creating device files. If not, then try:
- replacing cables/terminators;
- connecting drive to another machine to see if it will see drive;
- connecting drive to another compatible SCSI interface (remember: DAT40 is LVD, another - DAT24/DAT8 are SE)

Please post the output from "ioscan -fn -H ..." where "..." is the hardware path of the *interface* ("INTERFACE" in the "H/W Type" field of the ioscan output).

[Nick D'Angelo]

It looks like it is indeed a h/w issue with the drive. I replaced the cable and same, intermittant.

We replaced the drive with another Seagate drive (or something close to that) and voila, no problems.

THanks.
