Help pls. unable to detect devices

[marshal_4]

Hi Gurus,

When i tried backinup using tar on my dds drive using HPUX machine is said that unable to open tar eventhough there is already a tape on it but when i tried configuring my Veritas Netbackup is said that there is no device detected. If this is the case do you thing there is no problem on my drive.

Thanks in advanced,
Marshal

Let's try a simple test first.

Let's make sure that the drive can read the tape. Make sure there is a tape in the drive.
# mt -t /dev/rmt/0m (assuming that is your drive device)

If there is a problem, please try another tape first. Failing that please provide the output of:
# ioscan -fnC tape

There are chances that the device is switched off its its an external tape drive or have a look at the terminators and SCSI cable.
If its internal, either the drive might be faulty or you are using a wrong device or other issues.
Best is to see if you can see the device as claimed in ioscan, use
ioscan -fnkCtape
also check the device if its 0m or 1m etc..
if it shows claimed, trying reconfiguring using insf

Hi there,

I already tried to delete the devices in /dev/rmt (0m, 1m, etc etc). After that i ran insf, then ioscan -funC tape, the tape was claimed and it has the devices installed.
But it can't still be detected in Netbackup

thanks

So what happens when you run some tests:

# mt -t /dev/rmt/0m rew

# tar cvf /dev/rmt/0m /stand/vmunix

Please publish the results.

I can still encounter the error unable to open tar

Please publish these:

# ioscan -fnC tape
and
# ll /usr/bin/tar

also if you could send the listing
ll /dev/rmt/
