3. 调整TSM DB 和LOG空间的大小
define dbvolume /tsmdata/dblog/db01.dsm formatsize=160 wait=yes
extend db 160
dfine logvloume /tsmdata/dblog/log01.dsm formatsize=100 wait=yes
extend log 100
define spacetrigger db fullpct=85 spaceexpansion=25 expansionprefix=/tsmdata/dblog/
define spacetrigger log fullpct=85 spaceexpansion=25 expansionprefix=/tsmdata/dblog/
reduce db 16
reduce log 8
delete dbvolume /usr/tivoli/tsm/server/bin/db.dsm
delete logvolume /usr/tivoli/tsm/server/bin/log.dsm
安装TSM SERVER时默认的db和log的大小分别是16，8MB。
4. 备份策略的设置
Storage management policies are rules your administrator defines in order to manage your backups and archives on the server（Storage managermanet policies是管理员为了在服务端管理备份和归档定义的一种规则）。You can associate (or bind) your data to these policies（你能够绑定你的数据到这些Policies）；when the data is backed up or archived, it is managed according to policy criteria（当数据被备份或归档被相应Policy标准管理）。Policy criteria include a policy domain, and a management class ，a policy set, a copy group。
policy决定了是否一个文件或目录适合备份或归档、保留多少个备份版本、非激活状态的备份和归档拷贝保留多长时间、拷贝存放在何处。
Policy daemon是一组有相类似备份或归档需求数据的客户机的集合（A policy domain is a group of clients with similar requirements for backing up and archiving data.）。Policy domains contain one or more policy sets。
A policy set is a group of one or more management classes。
A management class is a collection of backup and archive copy groups that establishes and contains specific storage management requirements for backing up and archiving data.
Within a management class, the specific backup and archive requirements are in copy groups. Copy groups define the specific storage management attributes that describe how the server manages backed up or archived data. Copy groups include both backup copy groups and archive copy groups. A management class can have one backup copy group, one archive copy group, both, or neither。
A、 创建备份 client node
B、 通过WEB方式建立Policy daemon，选择object class/Policy daemon/define a Policy daemon
C、 选择Policy daemon下面的.Policy sets/define a policy sets，并将policy set给Active
D、 选择Policy sets下面的ManageClass/define a manageclass
E、 选择ManagClass下面的Copy Group
F、 将Client node分配到相应的Policy daemon
