Red Hat安装虚拟带库
1、安装五个包
# yum -y install lzo-devel sg3_utils lsscsi mtx mt-st
mtx源码:http://sourceforge.net/
2、下载最新版的mhvtl
mhvtl-2014-09-07.tgz
3、编译内核模块
# cd mhvtl-1.5
# cd kernel
# make
# make install
4、创建mhvtl用户
# useradd -c "vitrual mhvtl" -M vtl
5、编译用户空间代码
# cd mhvtl-1.5
# make
# make install
6、修改权限,不修改启动不了mhvtl
# chown -R vtl:vtl /opt/mhvtl
/etc/mhvtl 是放配置文件的地方
/opt/mhvtl 是放模拟磁带文件的地方
7、建立配置文件
# service mhvtl
Could not locate library config file: /etc/mhvtl/library_contents.10
Creating a default one
Please stop mhvtl & edit /etc/mhvtl/library_contents.10 to suit your requirements
Could not locate library config file: /etc/mhvtl/library_contents.30
Creating a default one
Please stop mhvtl & edit /etc/mhvtl/library_contents.30 to suit your requirements
Usage: /etc/init.d/mhvtl {start|stop|shutdown}
8、查看配置文件
# cat /etc/mhvtl/mhvtl.conf
# Home directory for config file(s)
MHVTL_CONFIG_PATH=/etc/mhvtl
# Default media capacity (500 M) #磁带容量
CAPACITY=500
# Set default verbosity [0|1|2|3]
VERBOSE=1
# Set kernel module debuging [0|1]
VTL_DEBUG=0
9、启动mhvtl
# /etc/init.d/mhvtl start
10、查看虚拟带库状态信息(lsscsi)
# lsscsi -g

2个机械臂 (/dev/sg10和/dev/sg11)
8个驱动器
11、查看机械臂状态(mtx)
# mtx -f /dev/sg10 status

4个驱动器,43个槽位
12、 将1槽位的磁带放到0驱动器中(Media Changer Tools)
# mtx -f /dev/sg10 load 1 0
Loading media from Storage Element 1 into drive 0...done
# mtx -f /dev/sg10 status
Storage Changer /dev/sg10:4 Drives, 43 Slots ( 4 Import/Export )

Data Transfer Element 2:Empty
Data Transfer Element 3:Empty
Storage Element 1:Empty
Storage Element 2:Full :VolumeTag=E01002L4
成功将磁带装入磁带驱动器中
13、查看st0状态(mt)
# 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 (LTO-4).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN
装入磁带:
- File number=0
- DR_OPEN IM_REP_EN
未装磁带:
- File number=-1
- BOT ONLINE IM_REP_EN
14、检查驱动器中磁头的位置(tell)
# mt -f /dev/st0 tell
At block 0.
15、向磁带中写入数据(cvf)
# tar cvf /dev/st0 mhvtl-2014-09-07.tgz
mhvtl-2014-09-07.tgz
# mt -f /dev/st0 tell
At block 0.
st打头的表示写入完成后会自动倒带,下次写入会覆盖之前的数据
# tar cvf /dev/nst0 mhvtl-2014-09-07.tgz
# mt -f /dev/nst0 tell
At block 37.
nst打头的表示写入完成后不会自动倒带
# tar rvf /dev/st0 mhvtl-2014-09-07.tgz
继续写入数据(不覆盖前边的内容)
# tar -zcvf /dev/st0 mhvtl-2014-09-07.tgz
写入数据并使用gzip压缩
16、查看磁带数据(tvf)
# mt -f /dev/nst0 rewind //倒带
# tar -tvf /dev/nst0
-rw-rw-r-- test/test 357615 2015-04-10 00:13 mhvtl-2014-09-07.tgz
# mt -f /dev/nst0 rewind
# mt -f /dev/nst0 fsf 1 //让磁头前进一个文件
# mt -f /dev/nst0 tell
At block 37.
17、清除磁带内容(erase)
# mt -f /dev/nst0 rewind
# mt -f /dev/nst0 erase
18、卸载磁带库(unload)
# mtx -f /dev/sg10 unload 1 0
Unloading drive 0 into Storage Element 1...done
