[root@nbumaster ~]# nbemmcmd -listhosts
NBEMMCMD, Version: 7.5
The following hosts were found:
server nbumaster
master nbumaster
app_cluster vcsdb-vip
media vcs2
media vcs1
Command completed successfully.
master server與雙機中的兩臺media server我都在dp.conf中加入了:
server=vcs1
server=vcs2
server=vcsdb-vip
之后,我在控制臺上面創(chuàng)建了一個storage unit group,然后包含了vcs1、vcs2的STU,vcs1的stu在前,vcs2的stu在后,我發(fā)現(xiàn),如果我切換Oracle到vcs2主機,NBU還是會使用vcs1的機械手進行寫入。這不是有問題么?
還有,根據(jù)NBU的高可用性文檔里面的建立非故障轉(zhuǎn)移集群,里面有如下話:
Use the NetBackup Administration Console to create a storage unit for each
application. Specify the virtual name of the application as media server name
for the storage unit.
但我在創(chuàng)建storage unit時,將vcsdb-vip(即浮動IP)設(shè)置為media server時,手工啟動job,報:Error nbjm (pid=3987) NBU status: 213, EMM status: Storage units are not available no storage units available for use (213)。
