Symptomer
I dette scenariet er presentasjonsserveren (mgmt-server) installert på en SDS-node.

Hendelser fra den primære MDM-en viser at SDS som mgmt-serveren er installert på, blir satt i vedlikeholdsmodus og startet på nytt.

Innvirkning

Varsler vises ikke i brukergrensesnittet.

Cause

Etter en omstart av en node kan det hende at presentasjonsserveren ikke viser varsler. Dette sporadiske problemet ser ut til å være knyttet til timing eller en kappløpstilstand under nodens oppstart.

Resolution

Du kan løse problemet ved å starte mgmt-server-tjenesten på nytt for å få varslene tilbake.

systemctl restart mgmt-server.service
