NetWorker: Hur återställer jag NMC-databasen?

[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

Obs! Om du inte har ovanstående sparade uppsättning kan du inte återställa NMC och det enda alternativet är att installera om det som en ny instans.
 

2) Öppna en administrativ/rotkommandotolk på NMC-servern och stoppa NMC GSTD-tjänsten (om den körs):

Windows: net stop gstd
Linux: systemctl stop gst

Notera: använd tasklist/Task Manager eller ps-kommandon för att säkerställa att gstd-tjänsten har stoppats
 

3) Använd kommandot cd för att navigera till NMC:s katalog för installationsfacket. Kontrollera att recoverpsm-kommandot finns med i den här katalogen. Det här kommandot används för att återställa NMC-databasen.

Windows: [NMC-installationskatalog\Hantering\GST\bin-plats
Linux: /opt/lgtonmc/bin

4) Kör recoverpsm-kommandot på NMC-servern:

Alternativ:
