Hi,
Is there any commnad to find – how many tapes in a tape drive.
Regards
Divakar
using tools we can identify the no of free tapes are available in drive.
I want to configure a Dell RD1000 tape drive on
solaris10 server and I do the following:
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
When you insert the tape in the tape drive and execute the below command, output should be like as shown below or else reboot the system using reconfiguration option..
