RMAN Backup to tape using Oracle Secure Backup

Question

I am trying to take 11g R2 (11.2.0.3) database backup using RMAN. I am using Oracle Secure Backup for configuring virtual tape library and virtual tape drive.
Whenever, I am running the RMAN backup script it simply hangs. While checking the backup job status from Oracle Secure Backup web interface, the job status are displaying 'pending resource availability'.
On, furthur investigating the job, the following error message are displayed,
" Dispatching job to run on oradb. Drive or volume on which mount attempted is unusable".
Library and Tape Creation:
mkdev -t library -o -S 4 -a oradb:/vlib -v vlib
mkdev -t tape -o -a ora11:/vt -v -l vlib -d 1 vt
Not able to fix this error. Need help

There is a VTL: http://mhvtl-linux-virtual-tape-library-community-forums.966029.n3.nabble.com/
  really work well with OSB 10.3.0.3 64bit, the version of it, fully tested by me , is 1.2
The installation guide of it here:
mh virtual tape & library system.
Instructions assume reader is familiar with the kernel build process.
There are two sections of code to build.
- The kernel module
- The user-space daemons.
Kernel module mhvtl:
==================
1) Make sure the kernel-devel package to match your running kernel is installed.
e.g.
RedHat AS 4 & 5:
# rpm -qa|grep kernel
kernel-2.6.9-34.0.1.EL
kernel-devel-2.6.9-34.0.1.EL
kernel-2.6.9-5.EL
kernel-devel-2.6.9-5.EL
kernel-utils-2.4-13.1.80
SLES 9 & 10:
# rpm -qa|grep kernel
2) Extract the mhvtl source code.
# tar xvfz mhvtl-2012-04-04.tgz
3) Change directory into the kernel driver source.
# cd mhvtl-1.2/kernel/
# make
# make install
User space daemons:
===================
Pre-req for a running mhvtl
- sg3_utils (http://sg.danny.cz/sg/sg3_utils.html)
Pre-req to build/compile userspace:
- zlib-devel
* To build an RPM
  ===============
cp mhvtl-YYYY-MM-DD.tar.gz /usr/src/packages/SOURCE/
cd /usr/src/packages/SOURCE
rpmbuild -tb mhvtl-YYYY-MM-DD.tar.gz
<wait for rpm build to complete>
rpm -Uvh /usr/src/packages/RPMS/<cpu type>/mhvtl-1.2-z.<cpu type>.rpm
(The rpm install will create system group & accounts vtl)
- Note: For RedHat, replace 'packages' with 'redhat'
* To build from tar archive (Debian / Ubuntu):
  ============================================
apt-get install lsscsi
apt-get install sg3_utils
To limit damage that may occur by wayward daemons, I highly recommend creating
a group and user called 'vtl'
# /usr/sbin/groupadd --system vtl
# /usr/sbin/useradd --system -c "Vitrual Tape Library" -d /opt/vtl -g vtl -m vtl
Now build user space daemons:
From the parent directory where you extracted the source.
# cd mhvtl-1.2
Build the binaries
# make
Install the rc script into /etc/init.d/ and binaries to /usr/local/bin/
# make install
Start daemons:
/etc/init.d/mhvtl start
Test:
Note: Make sure the 'mtx' & 'lsscsi' utilities are installed
The virtual devices are attached to HBA #5 in this example.
e.g.
# lsscsi -g
