NetBackup7.7 Master Server改名

下面步骤描述如何把NetBackup7.7版本的Master Server从oldmaster改成newmaster。
1. 停止NetBackup进程
2. 备份/usr/openv用于回退。
3. 判断新主机名的正确性
# bpclntcmd -is_local_host newmaster
newmaster is a local host

4. 修改bp.conf, vm.conf
5. 启动emm进程
# nbdbms_start_stop start
# /usr/openv/netbackup/bin/nbemm
# bpps
root       6204      1  2 23:38 ?       00:00:00 /usr/openv/db//bin/NB_dbsrv @/usr/openv/var/global/server.conf @/usr/openv/var/global/databases.conf -hn 5
root       6235      1  0 23:38 ?       00:00:00 /usr/openv/netbackup/bin/nbemm

# nbemmcmd -listhosts
NBEMMCMD, Version: 7.7
The following hosts were found:
server           newmaster
master          oldmaster

7. 修改emm数据库名称
 # nbdb_admin -vxdbms_nb_server newmaster
Database server name updated successfully.

# nbemmcmd -renamehost -machinename oldmaster -machinetype master -newmachinename newmaster
NBEMMCMD, Version: 7.7
Command completed successfully.

# nbemmcmd -listhosts
NBEMMCMD, Version: 7.7
The following hosts were found:
server           newmaster
master           newmaster
Command completed successfully.

# nbemmcmd -updatehost -machinename  newmaster  -machinetype master -operatingsystem linux

8. 重启emm数据库和nbemm
9. 验证
# nbdb_ping
Database [NBDB] is alive and well on server [NB_newmaster].

# nbdb_admin -validate -full

10. 启动NetBackup进程bp.start_all
11. 重新扫描配置信息
nbemmcmd -deletealldevices -allrecords
12. 用Wizard生产配置信息

注意：重启可以有可能会出现看不到policy情况，给oldmaster一个解析即可。

13. 修改media server的emm名称
nbemmcmd -setemmserver -emmservername oldmaster -newemmservername newmaster

14.修改image/media DB
bpimage -newserver newmaster -oldserver oldmaster
bpmedia -movedb -allvolumes -oldserver oldmaster -newserver newmaster
