HPUX not recognizing tape drive

I have a tape drive hooked up to a J6000 workstation running HPUX 11.11

It has a tape drive hooked up to it, P/N HP-C6368A printed on back.

This is what it shows when I do an ioscan -fn:

unknown -1 10/0/15/0.3.0 - UNCLAIMED UNKNOWN HP C5683A

We have another machine with the exact drive on it, a C3000 running 10.20. It works just fine.

There is no /dev/rmt stuff going on at all. How do I get access to this drive?

Re: HPUX not recognizing tape drive

Load the drivers. I think it's "stape" for that drive.

You can use "sam" to load the drivers.

Good luck,

Re: HPUX not recognizing tape drive


Okay, I loaded the stape drivers. Now when I try to use fbackup, it says:

/dev/rmt/1m is not a valid device file for backup. What does that mean? I can't really get anything to write to the drive.

Re: HPUX not recognizing tape drive

Can you post your full ioscan output?

It should be either stape, scsi1, scsi2, or scsi3 as the driver...

Re: HPUX not recognizing tape drive

HP's basic rule for HW failure is it's got to be seen in ioscan as a CLAIMED device, the kernel driver is missing, or its bad. Use the "...mt..." command to evaluate this device. Use the "...lsdev..." command to check for the kernel driver.

"...mt -t /dev/rmt/0m rew..."

-and-

"...lsdev | grep stape..."

After inserting a good tape into the drive, and after cleaning it, and the "...mt..." command hangs or returns I/O error then there's an HW issue.

Reboot.

After reboot does the ioscan still show unclaimed?

"...ioscan -fknC tape..."

Re: HPUX not recognizing tape drive

Sorry - disk is my specialty, not workstations or tape.

However, I did find some information that might help.

I found a reference to the chipset on the J6000 - apparently the driver you use is dependent upon the SCSI chipset...

The J-class has a Symbios C896 chipset.

You should have a "c8xx" driver: http://docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/5187-0172/5187-0172_top.html&con=/hpux/onlinedocs/5187-0172/00/00/41-con.html&toc=/hpux/onlinedocs/5187-0172/00/00/41-toc.html&searchterms=j6000%20scsi&queryid=20030314-131145

for documentation on the driver. Please read this as it contains a list of patches required.

I hope this helps.
