1-First I found the drive name by using command:
#iostat -En
and this is the output:

c2t0d0 Soft Errors: 1 Hard Errors: 0 Transport Errors: 0
Vendor: DELL Product: RD1000 Revision: 0053 Serial No:
Size: 0.00GB
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 1 Predictive Failure Analysis: 0

2-I try the mt command on this device as follow:

#mt -f /dev/dsk/c2t0d0 and the output is :No such device

when I try #mt -f /dev/dsk/c2t0d0p0 the output is :Device is busy

3-I try to check which process has locked the Tape drive by using:

# fuser -u /dev/dsk/c2t0d0p0 I found the process is “Vold”

4-I stop the volume management process by using:

# /etc/init.d/volmgt stop

and i checked again:

# mt -f /dev/dsk/c2t0d0p0 status

mt: Inappropriate ioctl for device

Notes: I used “tapes” command and still “/dev/rmt” empty

Any respond ASAP will be really appreciated.
You can respond me on my e-mail: m_aboelgheit@yahoo.com
