Hello All, I'm in trouble here . Any pointers gladly
appreciated . Including where else to post this query .
a general user can get 'mt' to get status (...) once the
tape is loaded . But using 'mtx' on the same device
illicits the below response .
sunny:jiml:~$ mtx -f /dev/rmt/0 status
mtx: Request Sense: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
mtx: READ ELEMENT STATUS Command Failed
Here are the permissions of the special files in question .
sunny:root:/dev$ dir /dev/rmt/0
2 lrwxrwxrwx 1 root root 56 Dec 30 22:23 /dev/rmt/0 ->
../../devices/pci@1f,0/pci@1/pci@1/SUNW,isptwo@4/st@4,0:
sunny:root:/dev$ dir /devices/pci@1f,0/pci@1/pci@1/SUNW,isptwo@4/st@4,0:

/devices/pci@1f,0/pci@1/pci@1/SUNW,isptwo@4/st@4,0:
I have added below a short 'truss' output while running the above
command as a general user . Anything else you may need please
just ask . Tia, JimL
