NetWorker: come ripristinare il database di NetWorker Management Console

Se è stato identificato un danneggiamento del database NMC, è possibile utilizzare il comando NetWorker recoverpsm per ripristinare il database NMC a un backup di nmcdb. Per impostazione predefinita, dovrebbe essere presente un flusso di lavoro di backup del server NMC all'interno della policy Server Protection predefinita. Assicurarsi che questa operazione sia pianificata e configurata correttamente per completare i backup del database NMC.

Per ulteriori informazioni sulla protezione del server NMC, consultare la Guida all'amministrazione di NetWorker e la Guida di riferimento ai comandi di NetWorker per entrambi savepsm e recoverpsm Opzioni. Questi documenti sono disponibili nella pagina del prodotto Dell NetWorker.

1. Assicurarsi che sia presente un backup del database NMC utilizzando il comando mminfo :

[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. Sul server NMC, aprire un prompt dei comandi root amministrativo per arrestare NMC GSTD Servizio (se in esecuzione):

Windows: net stop gstd
Linux: systemctl stop gst

Utilizzare tasklist/Task Manager oppure PS comandi per garantire che il GSTD Il servizio è stato arrestato.

3. Utilizzare il comando CD per passare alla directory bin di installazione di NMC. Verificare che il recoverpsm è elencato in questa directory. Questo comando viene utilizzato per ripristinare il database NMC.

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

4. Eseguire recoverpsm sul server NMC:

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

Opzioni:

Esempio:

[root@linux1 bin]# ./recoverpsm -f -s linux1.amer.lan -c linux1.amer.lan -p Pa$$w0rd01 /nsr/nmc/nmcdb_stage

5. Sul server NMC, aprire un prompt dei comandi root amministrativo per arrestare NMC GSTD servizio:

6. Assicurarsi di potersi connettere a NMC.

7. Monitorare il gstd.raw per rilevare eventuali errori durante l'avvio del servizio NMC:

I file .. del server NMC \Management\GSTD\logs\gstd.raw o /opt/lgtonmc/logs/gstd.raw possono essere utilizzati per confermare se NMCDB è danneggiato:
