MHVTL与TSM的完美结合
丁振海
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 8.0K drwxr-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 lbinfo lrwxrwxrwx 1 root root 8 Oct 21 11:38 mt0 -> /dev/sg2 lrwxrwxrwx 1 root root 8 Oct 21 11:38 mt1 -> /dev/sg3 lrwxrwxrwx 1 root root 8 Oct 21 11:38 mt2 -> /dev/sg4 lrwxrwxrwx 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。
