NetWorker: Problemer med NMC-service og tilgængelighed (generel fejlfindingsvejledning)

Denne KB kan følges, hvis NetWorker Management Console-serveren (NMC) er installeret på en NetWorker-server eller en enkeltstående vært. Før du fortsætter, skal du bekræfte miljøoplysningerne. 

Indledende trin

• Er NMC installeret på en NetWorker-server eller en enkeltstående vært?
• Indsaml miljøoplysninger: NetWorker: Metoder til at identificere NetWorker-softwareversion
• Kører NMC-tjenesten:
  • Linux: systemctl status gst

• Windows: I services.msc skal EMC GST-databasen, EMC GST-tjenesten og EMC GST-webtjenesten køre.

 

• Kan NMC-klienten få adgang til NMC-serveren?:
  • Windows PowerShell:

tnc nmc-server-hostname -port 9000
tnc nmc-server-hostname -port 5432

Problemer og symptomer

• NetWorker-servertjenester er oppe, serverfunktionalitet kan observeres ved hjælp af kommandoen nsrwatch på NetWorker-serveren, fra NetWorker Web User Interface (NWUI) (hvis installeret) eller fra en anden NMC-server med netværks- og adgangsrettigheder til NetWorker-serveren.

Indstillinger for returnering af funktionalitet baseret på operativsystem:

Linux

Gendannelse

Genkonfigurer

Geninstallere

Windows

Tjenester

1. Åbn services.msc
2 på NMC-serveren. Gennemgå hver af EMC GST-tjenesterne .
3. Bekræft, at tjenesteejeren er standard:
