2 TSM的日常操作

2.1 备份服务器 2.1.1 启动备份服务器

执行以下步骤

1. 切换到tsm实例用户

# su - tsminst1

查看TSM server 数据库是否启动 #ps -ef |grep -i dsm 2. 启动实例

$ db2start 3. 查看所有数据库

$ db2 list db directory 4. 连接数据库

$ db2 connect to tsmdb1 查看其配置信息

$ db2 get db cfg for tsmdb1 5. 启动TSM进程

进入tsm服务器程序的安装路径下： $ cd /tsmdata/tsminst

$ /opt/tivoli/tsm/server/bin/dsmserv 如果需要TSM启动到后台，使用以下命令启动 $ /opt/tivoli/tsm/server/bin/dsmserv -q & 6. 查看启动是否成功

登录到TSM管理控制台，查看TSM是否启动成功 $ su - root

# cd /usr/tivoli/tsm/client/ba/bin # ./dsmadmc

输入用户名admin，密码111111Aa TSM> q status

如果可以正常显示TSM服务器的信息，说明TSM启动成功。

2.1.2 停止备份服务器

1. 切换到/usr/tivoli/tsm/client/ba/bin目录下，运行dsmadmc，输入口令/密码admin/***** 进入管理员界面

2. 禁止服务器接收新的客户端访问TSM>disable sessions 3. 查看当前客户端与服务器的连接TSM>query session

4. 等待客户端结束备份或直接中断连接TSM>cancel session XX(all) 5. 查看服务器进程TSM>query process

6. 等待服务器进程结束或直接中断进程TSM>cancel process

q mount检查是否有磁带被使用。

q request检查是否有需要人工干预的操作。 7. 停止服务器，在提示符下输入halt

TSM>halt

2.1.3 备份服务器选项信息

TSMSERVER>q opt

2.1.4 修改服务器选项信息

TSMSERVER>setopt MaxSessions 300

2.2 备份节点数据查询 2.2.1 TSM server端查询

TSMSERVER>q nodedata DBSERVER2_DEDUP

TSMSERVER>q content /stg1/vol1.dsm

2.2.2 TSM client端查询

本机的客户端数据查询

# dsmc q backup /tmp/tsm6.3_client –inactive

异机的客户端数据查询

#dsmc q backup /tmp/ -virtualnodename=DBSERVER2_DEDUP -inactive

2.3 备份节点数据恢复

2.4 备份密码修改 2.4.1 修改过期时间

修改服务器及备份节点的密码到期时间

TSMSERVER>set passexp 9999

ANR2092I Password expiration period set to 9999 days. 修改备份节点的密码到期时间

TSMSERVER>set passexp 999 no=ora_node

ANR2199I Password expiration period for node ORA_NODE set to 999 days. 修改服务器的密码到期时间

TSMSERVER>set passexp 999 admin=admin

ANR2299I Password expiration period for administrator ADMIN set to 999 days.

2.4.2 更新密码

更新管理员密码

TSMSERVER>update admin admin 1****Aa passexp=999 ANR2071I Administrator ADMIN updated 更新节点密码

TSMSERVER>update no ora_node 12345670 ANR2063I Node ORA_NODE updated.

2.5 更换磁带介质 2.5.1 磁带出库

将卷名为151AAXL5的磁带出库

TSMSERVER>checkout libv ts3100 151AAXL5 ANS8003I Process number 4 started.

2.5.2 已出库磁带入库

将出库的磁带重新加入磁带库

TSMSERVER>checkin libv ts3100 search=bulk status=private waitt=0

ANS8003I Process number 6 started. 如果查询request出现以下状况 TSMSERVER>q request

ANR8352I Requests outstanding:

ANR8373I 002: Fill the bulk entry/exit port of library TS3100 with all LTO volumes to be processed within 59 minute(s); issue 'REPLY' along with the request ID when ready. 需要执行以下操作，迅速完成磁带入库 TSMSERVER>reply 2

ANR8499I Command accepted.

2.5.3 新磁带入库

将新的入库磁带放入I/O槽中，执行以下命令：

TSMSERVER>checkin libv ts3100 search=bulk status=scratch ANS8003I Process number 6 started.

TSM> label libvol ts3100 search=b labelsource=barcode checkin=scratch overwrite=yes

将新磁带直接放入带库中，需要执行以下命令： TSM> audit libv ts3100

TSM> label libvol ts3100 search=b labelsource=barcode checkin=scratch overwrite=yes

3 TSM服务器的备份恢复

3.1 TSM服务器的备份 3.1.1 备份准备工作

设置备份设备类型

TSMSERVER>set dbrecovery tape

ANR2782I SET DBRECOVERY completed successfully and device class for automatic DB backup is set to TAPE.

3.1.2 手动备份服务器数据库

备份卷信息到磁盘上

TSMSERVER>backup volhistory file=/tsmdbbak/volhist.out 备份设备配置信息到磁盘上

TSMSERVER>backup devconfig file=/tsmdbbak/devcnfg.out 备份数据库空间信息

TSMSERVER>query dbspace >> /tmp/dbinfo.txt TSMSERVER>query log f=d >> /tmp/loginfo.txt

Output of command redirected to file '/tmp/dbinfo.txt' 备份数据库

TSMSERVER>backup db devc=tape type=full volumenames=151AAXL5 ANR2280I Full database backup started as process 14. ANS8003I Process number 14 started.

3.1.3 自动备份服务器数据库

3.2 确认灾难恢复介质 3.2.1 查询灾难备份磁带介质

TSMSERVER>q drm

Volume Name State Last Update Automated Date/Time LibName ------------ ------------- -------------- ------------ 153AAXL5 Mountable 12/02/2011 15:15:27 TS3100

3.2.2 查询灾难备份数据参数信息

TSMSERVER>q drmst
