http://lhf0616.blog.51cto.com/2920914/535701

 

在安装mhvtl之前，先安装下面的包
[root@station90 ~]# yum -y install zlib-devel mt-st mtx  lsscsi
接着创建vtl用户
[root@station90 ~]# useradd vtl
[root@station90 ~]# echo "redhat" | passwd --stdin vtl
创建以下两个目录
[root@station90 ~]# mkdir /opt/mhvtl
[root@station90 ~]# mkdir /etc/mhvtl
[root@station90 ~]# chown -R vtl:vtl /opt/mhvtl /etc/mhvtl/
解压mhvtl软件包
[root@station90 stage]# tar -zxvf mhvtl.tgz
[root@station90 stage]# cd mhvtl-0.18/
[root@station90 mhvtl-0.18]# ls
doc include kernel man README usr
etc INSTALL Makefile mhvtl.spec scripts
编译mhvtl
[root@station90 mhvtl-0.18]# make distclean
[root@station90 mhvtl-0.18]# cd kernel/
[root@station90 kernel]# make;make install
[root@station90 kernel]# cd ..
[root@station90 mhvtl-0.18]# ls
doc include kernel man README usr
etc INSTALL Makefile mhvtl.spec scripts
[root@station90 mhvtl-0.18]# make;make install
启动mhvtl
[root@station90 ~]# /etc/init.d/mhvtl start

sg10,sg11是机械手
查看机械手的状态
[root@station90 network-scripts]# mtx -f /dev/sg10 status

查看磁带的状态
[root@station90 log]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x46 (no translation).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN //
BOT The tape is positioned at the beginning of the first file.
DR_OPEN Door is open. Depending on the type of drive, this usually means that the drive does not have a tape in place.
