Connect external Tape drive

I've connected an external tape drive to an HP-UX 10.20 server. With ioscan -funCtape I see that the system has detected this tape drive:
ioscan -funCtape

I try to run tar -cvf /dev/rmt/1m /apl*
and I always get the error message:
tar: cannot open /dev/rmt/1m
What could be the problem?

Re: Connect external Tape drive

Schneider,

The ARCHIVE Python 25588-XXX is an autochanger, correct? Is there a tape actually loaded into the tape drive? Write enabled?

Re: Connect external Tape drive

Try the command

# mt -f filename rew

to see if the drive is seen that way.

Perhaps something is wrong with the device files. Try removing them and then recreating them (mknod or SAM).
