本文利用mhvtl虚拟带库以及tsm软件，搭建备份恢复测试环境，供初学者参考！
虚拟带库的设置
[root@tsmsrv ~]# lsscsi -g[2:0:0:0] disk VMware, VMware Virtual S 1.0 /dev/sda /dev/sg0[3:0:0:0] cd/dvd NECVMWar VMware SATA CD00 1.00 /dev/sr0 /dev/sg1[33:0:8:0] mediumx STK SL500 0105 /dev/sch0 /dev/sg6[33:0:9:0] tape STK 9840 0105 - /dev/sg2[33:0:10:0] tape STK 9840 0105 - /dev/sg3[33:0:11:0] tape STK 9840 0105 - /dev/sg4[33:0:12:0] tape STK 9840 0105 - /dev/sg5
编辑mhvtl.conf文件，将磁带的容量调整为20G。[root@tsmsrv ~]# cat /etc/mhvtl/mhvtl.conf ..........# Default media capacity (500 M)CAPACITY=20480
运行/opt/tivoli/tsm/devices/bin/autoconf -a命令，会产生如下文件：
[root@tsmsrv ~]# la /dev/tsmscsi/total 8.0Kdrwxr-xr-x 2 root root 180 Oct 21 11:38 .drwxr-xr-x 19 root root 4.4K Oct 21 11:38 ..lrwxrwxrwx 1 root root 8 Oct 21 11:38 lb0 -> /dev/sg6-rw-r--r-- 1 root root 173 Oct 21 11:38 lbinfolrwxrwxrwx 1 root root 8 Oct 21 11:38 mt0 -> /dev/sg2lrwxrwxrwx 1 root root 8 Oct 21 11:38 mt1 -> /dev/sg3lrwxrwxrwx 1 root root 8 Oct 21 11:38 mt2 -> /dev/sg4lrwxrwxrwx 1 root root 8 Oct 21 11:38 mt3 -> /dev/sg5-rw-r--r-- 1 root root 442 Oct 21 11:38 mtinfo
在linux下面，定义带库的时候，必须指定其位于/dev/tsmscsi下的路径。
