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。

TSM中定义带库

//定义虚拟带库
