Description Mindy Preston 2005-06-20 21:02:13 UTC
Description of problem: A SCSI tape drive can be read from and written to, but the command 'mt tell' fails with 'no such device', even when the correct device is specified. 'mt tell' succeeded with the same machine and tape drive under a 2.4 kernel and earlier Red Hat release. I believe this is a kernel issue that was backported into 2.6.9 because it is mentioned on kerneltrap.org ( http://kerneltrap.org/node/4351 ). Version-Release number of selected component (if applicable): kernel-2.6.9-11.EL.SMP How reproducible: 'mt -f <scsi device> tell' Steps to Reproduce: 1. attach a SCSI drive to the system 2. "dmesg | grep Attached" to get the proper device 3. confirm read/write from that device succeed, as well as other mt commands 4. "mt tell" Actual results: /dev/st0: No such device Expected results: The block # the tape is currently on Additional info:

Created attachment 116629 [details] Fix for faulty return value This should be all that's needed to solve the problem. I don't have a tape drive in my test system, so any testing of this would be appreciated.

I have since moved the tape drive to a different machine, since the user needed access to some data saved on DLTs. Unfortunately, I won't be able to test this for you in the near future.
