NetWorker – Sådan gendannes NetWorker Management Console-databasen

Hvis du har identificeret fejl i NMC-databasen, kan du bruge NetWorker recoverpsm kommando til at gendanne NMC-databasen til en sikkerhedskopi af nmcdb. Som standard bør der være et NMC-serverbackuparbejdsforløb i standardpolitikken for serverbeskyttelse. Sørg for, at dette er planlagt og konfigureret korrekt til at fuldføre sikkerhedskopiering af NMC-databasen.

Du kan finde flere oplysninger om NMC-serverbeskyttelse i NetWorker-administrationsvejledningen og NetWorker-kommandoreferencevejledningen for begge savepsm og recoverpsm indstillinger. Disse dokumenter findes på Dell NetWorker-produktsiden.

1. Sørg for, at der er en sikkerhedskopi af NMC-databasen ved hjælp af mminfo kommando:

[root@linux1 ~]# mminfo -avot -q client=linux1.amer.lan | grep nmcdb_stage
ClientBackupPool.001 Data Domain linux1.amer.lan 08/15/2022 02:00:17 PM 53 MB 687518690 cb full /nsr/nmc/nmcdb_stage

2. Åbn en administrativ rodkommandoprompt på NMC-serveren for at stoppe NMC GSTD Service (hvis kørende):

Windows: net stop gstd
Linux: systemctl stop gst

Brug tasklist/Task Manager eller PS Kommandoer til at sikre, at ikonet GSTD Tjenesten er stoppet.

3. Brug CD kommando til at gå til NMC's installationsbin-mappe. Kontrollér, at recoverpsm Kommandoen er angivet i denne mappe. Denne kommando bruges til at gendanne NMC-databasen.

Windows: [NMC Installation Dir\Management\GST\bin
Linux: /opt/lgtonmc/bin
 

4. Kør recoverpsm kommando på NMC-serveren:

recoverpsm [-s server] [-c client-name] [-d destination] [-p pass-phrase] [-t time] [-hfO] Staging_Directory

Indstillinger:

5. Åbn en administrativ rodkommandoprompt på NMC-serveren for at stoppe NMC GSTD tjeneste:

6. Sørg for, at du kan oprette forbindelse til NMC.

7. Overvåg gstd.raw for eventuelle fejl under opstart af NMC-tjenesten:

NMC-serverens .. \Management\GSTD\logs\gstd.raw eller /opt/lgtonmc/logs/gstd.raw kan bruges til at bekræfte, om der er NMCDB-beskadigelse:
