（求版主幫忙）雙機(jī)環(huán)境，app_cluster備份問(wèn)題。

zyl19861126

這是實(shí)驗(yàn)環(huán)境。

雙機(jī)：vcs1、vcs2主機(jī)，應(yīng)用為oracle數(shù)據(jù)庫(kù)，主備方式。

我在vcs1、vcs2主機(jī)各自安裝了media server，master server指向nbumaster這臺(tái)主機(jī)。我現(xiàn)在想法是，創(chuàng)建策略時(shí)使用Oracle浮動(dòng)IP地址（vcsdb-vip)，這樣不論Oracle切換到哪臺(tái)機(jī)器我都能夠備份，備份方式要以Lan-Free走SAN網(wǎng)絡(luò)。

創(chuàng)建app_cluster如下所示：

nbemmcmd -addhost -machinename vcsdb-vip -machinetype app_cluster

nbemmcmd -updatehost -add_server_to_app_cluster -machinename vcs1 \
         -machinetype media -clustername vcsdb-vip                                  \
         -netbackupversion 7.5 -masterserver nbumaster

nbemmcmd -updatehost -add_server_to_app_cluster -machinename vcs2 \
         -machinetype media -clustername vcsdb-vip                                  \
         -netbackupversion 7.5 -masterserver nbumaster

nbemmcmd列出主機(jī)如下：

[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(jī)中的兩臺(tái)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(tái)上面創(chuàng)建了一個(gè)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(jī)，NBU還是會(huì)使用vcs1的機(jī)械手進(jìn)行寫入。這不是有問(wèn)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(shí)，將vcsdb-vip（即浮動(dòng)IP）設(shè)置為media server時(shí)，手工啟動(dòng)job，報(bào)：Error nbjm (pid=3987) NBU status: 213, EMM status: Storage units are not available no storage units available for use  (213)。

請(qǐng)問(wèn)，我創(chuàng)建app_cluster方式有哪些地方需要改進(jìn)的？

我發(fā)覺切換后，vcs2的數(shù)據(jù)通過(guò)lan方式傳給vcs1了，然后再由vcs1來(lái)執(zhí)行寫入了。我要的是，不論切換到哪臺(tái)機(jī)器，都要通過(guò)SAN寫入啊。 還有，是不是我的license問(wèn)題，此license包含了media server的全部功能，如果只是san media server的話，是不是能夠成功？

LS的兄弟，你能夠用Oracle的浮動(dòng)IP地址設(shè)置storage unit么？ 還是創(chuàng)建storage unit group?

    怪了。我創(chuàng)建了app_cluster，如下：

[root@nbumaster ~]# nbemmcmd -listhosts -verbose

        MasterServerName = "nbumaster"
        NetBackupVersion = 7.5.0.0 (750000)
        OperatingSystem = linux (16)
        ScanAbility = 5

        ClusterName = ""
        MachineName = "vcs2"
        FQName = "vcs2"
        LocalDriveSeed = ""
        MachineDescription = ""
        MachineFlags = 0x77
        MachineNbuType = media (1)
        MachineState = active for tape and disk jobs (14)

        NetBackupVersion = 0.0.0.0 (0)
        Active Node Name = ""

但active node name確是空的，而oracle在vcs1上面。此時(shí)我用vcsdb-vip弄的stu會(huì)報(bào)無(wú)介質(zhì)錯(cuò)誤。
