You have to cancel the process or session that is using that tape before 
you can dismount it.  You can only dismount a tape whose status is IDLE. 
Since that tape is mounted read-only and it is waiting for a second tape 
to be mounted, a reclamation or move data process is probably running.

Try:
q proc
cancel proc <process#>

cannot dismount tape






Hi,
 
               I´m having a problem, almost everyday, when I execute q 
mount command, I receive something like that:
 
ANR8330I DLT volume DYI514 is mounted R/O in drive MT-SCSI-ID-3 
(/dev/rmt/3mt), status: IN USE.
ANR8379I Mount point in device class DC-SUNL1000 is waiting for the volume 
mount to complete, status: WAITING FOR VOLUME.
ANR8334I         2 matches found.

 

 

               DYI514 is tape number, and not always is the same; but when 
I execute  command "DISMOUNT VOLUME dyi514", I received "ANR8348E DISMOUNT 
VOLUME: Volume DYI514 is not "Idle"".
 
               It could spent many days in that state and I have to 
restart the server.
 
               What could be the problem?
 
               Thanks in advance.
 
Marcelo.
