NetWorker: Come ripristinare il database NMC?

[root@linux1 ~]# mminfo -avot -q client=linux1.amer.lan -t "today" | 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

Nota: Se non si dispone del saveset di cui sopra, non è possibile ripristinare NMC e l'unica opzione è reinstallarlo come nuova istanza.
 

2) Sul server NMC, aprire un prompt dei comandi amministrativi/root, arrestare il servizio NMC GSTD (se in esecuzione):

Windows: net stop gstd
Linux: systemctl stop gst

Nota: utilizzare tasklist/Task Manager o i comandi ps per assicurarsi che il servizio gstd sia stato arrestato
 

3) Utilizzare il comando cd per passare alla directory bin di installazione di NMC. Verificare che il comando recoverpsm sia elencato in questa directory. Questo comando verrà utilizzato per ripristinare il database NMC.

Windows: [Directory installazione NMC\Management\GST\bin
Linux: /opt/lgtonmc/bin

4) Eseguire il comando recoverpsm sul server NMC:
