NetWorker: Sådan gendannes 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

Bemærk: Hvis du ikke har ovenstående saveset, kan du ikke gendanne NMC, og den eneste mulighed er at geninstallere det som en ny forekomst.
 

2) Åbn en administrations-/rodkommandoprompt på NMC-serveren, og stop NMC GSTD-tjenesten (hvis den kører):

Windows: net stop gstd
Linux: systemctl stop gst

Bemærk: Brug kommandoen tasklist/Task Manager eller ps til at sikre, at gstd-tjenesten er stoppet
 

3) Brug kommandoen cd til at navigere til NMC's installationsbin-mappe. Kontroller, at kommandoen recoverpsm 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 kommandoen recoverpsm på NMC-serveren:
