1、一Mhvtl+mhvtl gui+iscsi1.安装：yum install lsscsi mt-st mtx zlib-devel sg3_utils zlib lzo-devel kernel-devel kernel-headers gcc接着创建vtl用户：#useradd vtl#passwd vtl#mkdir /opt/mhvtl# mkdir /etc/mhvtl# chown -Rf vtl:vtl /opt/mhvtl#chown -Rf vtl: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MHVL

13、i_level=0 type=1 device_blocked=0 timeout=900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:rootcentos001 mhvtl-1.4# cat /etc/mhvtl/mhvtl.conf# Home directory for config file(s)MHVTL_CONFIG_PATH=/etc/mhvtl# Default media capacity (500 M)CAPACITY=500# Set default verbosity 0|1|2|
14、3VERBOSE=1# Set kernel module debuging 0|1VTL_DEBUG=0capacity=500就是指默认容量为500MB。3.简单应用：查看机械手状态：rootcentos001 mhvtl-1.4# mtx -f /dev/sg10 status Storage Changer /dev/sg10:4 Drives, 43 Slots ( 4 Import/Export )Data Transfer Element 0:EmptyData Transfer Element 1:EmptyData Transfer Element 2:EmptyData Transfer Element 3:Empty Storage Eleme
