Here is an example of enabling SECURITY PROTOCOL IN/OUT op code with scst.
I have tested KMS feature of NetBackup 7.1 on AIX 6.1 media server thru iSCSI.
(NBU's ovpass driver on AIX does not support iSCSI..., so robot is controlled by linux media server)
For quick deployment, I built VTL on Scientific Linux CERN 5.6.
1) Install Required Packages
# yum install gcc
# yum install kernel-devel
# yum install rpm-build
2) Build and install scst
# wget
http://linuxsoft.cern.ch/cern/slc56/updates/x86_64/SRPMS/scst-1.0.1.1-3.cern.src.rpm# mkdir -p /usr/src/redhat
# rpm -i scst-1.0.1.1-3.cern.src.rpm
# cd /usr/src/redhat/SOURCES
# tar xzf scst-1.0.1.1.tar.gz
# mv scst-1.0.1.1.tar.gz scst-1.0.1.1.tar.gz.org
# cp scst-1.0.1.1/src/scst_cdbprobe.h scst-1.0.1.1/src/scst_cdbprobe.h.org
# vi scst-1.0.1.1/src/scst_cdbprobe.h

3) Install mhvtl
# tar xzf mhvtl-2011-06-25.tgz
# cd mhvtl-0.18/kernel
# make
# make install
# rpm -i mhvtl-0.18-17.x86_64.rpm
# cp -p /etc/init.d/mhvtl /tmp/mhvtl.org
# vi /etc/init.d/mhvtl
# diff /tmp/mhvtl.org /etc/init.d/mhvtl

< # chkconfig: - 30 30
---
> # chkconfig: - 40 88
# chkconfig --del mhvtl
# chkconfig --add mhvtl
# service mhvtl start
4) Example configuration for default settings
# cat /etc/scst.conf
