Avamar: Data Domain visas inte i Avamar webb- eller administratörskonsolen

• Data Domain visas inte i Avamar-användargränssnittet (UI) eller Avamar-administratörskonsolen.
• Att starta om Management Console Service (MCS) löser inte problemet.

admin@av-server:~/>: mccli dd show-prop --name=ddve01.lab.com

admin@av-server:~/>: 

• Starta om med kommandoradsgränssnittet (CLI) med hjälp av mcddrsnmp löser inte problemet.

• Men om du loggar in på Avamar-gränssnittet använder du MCUser och root, lösenordet är ett annat.
• På GSAN-nivå är lösenordet för root och MCUser korrekta:

admin@av-server:~/>: avmgr logn --id=root --ap=*******
1  Request succeeded

Lös problemet genom att kryptera rotserverlösenordet i mcserver.xml och starta om MCS. Detta startar Data Domain SNMP Manager, vilket gör Data Domain synlig i både Avamar-gränssnittet och MCCLI.

• Sätt rotserverlösenordet i oformaterad text på /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml och kryptera igen.
• Säkerhetskopiering mcserver.xml:

cp -p /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml

• Redigera /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml och lägg rotserverlösenordet som vanlig text i rootAP-värdet:

admin@av-server:/home/admin/#: vi /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
                <entry key="backuprestoreAP" value="{AES}hMKAX9yMuHxbyvltADTR0NALyFSXDMMTCQIqYkry5Bk=" />
                <entry key="backuponlyAP" value="{AES}hMKAX9yMuHxbyvltADTR0NALyFSXDMMTCQIqYkry5Bk=" />
                <entry key="rootAP" value="change-password-here" />
