HP-UX 10.20 Tape Permission Denied

[Suresh Sandasani]

Hello All,

I have an internal DDS tape drive getting the following error when I even check the status.
Can someone help me ?

# mt -t /dev/rmt/0mn status
/dev/rmt/0mn: Permission denied

could the tape be write protected at all ?

what about an alternate tape ?

Hi,

It seems to me that the tape is catched by some process.
the following steps may be done:
1. ps -ef |grep 0m or
lsof /dev/rmt/0m or lsof /dev/rmt/0mn
2. Reboot the computer
3. Shutdown the computer, switch it off and switch it on.

Hi,

Pls check device file privilegies, must be like to:
crw-rw-rw- 2 bin bin 205 0x040040 Apr 2 14:22 0mn

Try rebuilding the device file using "insf" command. To detailed info "man insf"

Hello,
check the tape & make sure it's not set to write-protect & try another tape.

Hi,
Check the permission of the /dev/rmt/0m.

# cd /dev/rmt
# ls -al | grep 0

They should be crw-rw-rw-

Thank you all,

Yes the tape was write-protected.
