"iostat -En" only shows harddisk errors.

Please show output of:
# mt -f /dev/rmt/3 status
and
# ls -al /dev/rmt/

Make sure the tape drve is powered on without any errors, and do this:
# devfsadm
# ls -al /dev/rmt

I have been using /dev/rmt/3 on this machine for two years.
I installed oracle secure backup and now i/dev/rmt is empty.

I brought the tape drive back to the office and it is seen on another machine.
How could I loose the whole /dev/rmt directory by just installing oracle secure backup?
How do I get back /dev/rmt?

Make sure Tape Drive is connected and online
try running devfsadm with root user. This will detect the tape drive and create the entries under /dev/rmt/
(http://docs.sun.com/app/docs/doc/806-0625/6j9vfill4?a=view)
now run mt stat command to check
