centos65+mhvtl+gui+iscsitgt虚拟磁带库的安装与应用剖析
一．Mhvtl+mhvtlgui+iscsi
1.安装：
yuminstalllsscsimt-stmtxzlib-develsg3_utilszliblzo-develkernel-develkernel-headersgcc
接着创建vtl用户：
#useraddvtl
#passwdvtl
#mkdir/opt/mhvtl
#mkdir/etc/mhvtl
#chown-Rfvtl:
vtl/opt/mhvtl
#chown-Rfvtl:
vtl/etc/mhvtl
（/etc/mhvtl为配置文件路径/opt/mhvtl为虚拟带库存储路径）
2.编译安装 MHVLT
#tar-zxvfmhvtl-2013-03-22.tgz
[root@centos001tool]#cdmhvtl-1.4
[root@centos001mhvtl-1.4]#cdkernel
[root@centos001kernel]#make;makeinstall
[root@centos001mhvtl-1.4]#make;makeinstall
如果未安装lzo和lzo-devel开发环境将收到如下报错：

Typicalerror（missinglzodevelpackage）lookslike:

这里的/dev/sg10和/dev/sg11是机械手。
这个默认的容量是500MB，这个可以查看mhvtl的配置文件mhvtl.conf:
[root@centos001mhvtl-1.4]#cat/etc/mhvtl/mhvtl.conf
#Homedirectoryforconfigfile（s）
MHVTL_CONFIG_PATH=/etc/mhvtl
#Defaultmediacapacity（500M）
CAPACITY=500
#Setdefaultverbosity[0|1|2|3]
VERBOSE=1
#Setkernelmoduledebuging[0|1]
VTL_DEBUG=0
capacity=500就是指默认容量为500MB。
3.简单应用：
