Symptoms

Nye lagringsnoder føjes til Avamar. Det er et replikeringsdestination.

Et replikeringsjob, der bruges til at arbejde, begynder at mislykkes med jævne mellemrum.

Som det kan ses i logfilerne, har Avamar-kilden en enkelt node.
Replikeringsjobbet kan oprette forbindelse til Avamar-målet vha. IP 10.1.1.30.
Den kan ikke nå ni af de noder, der er præsenteret for den i afsendelsestabellen.
 
  • Målsystemets IP-adresse er blevet bekræftet til at være korrekt
  • Login-legitimationsoplysningerne på destinationen er korrekte

Cause

Da Avamar-målet blev udvidet, blev de nødvendige firewallporte til at muliggøre tilslutning til de nye noder ikke åbnet.
Når replikeringen opretter forbindelse til original storage-noder, lykkes det.
Når replikeringen opretter forbindelse til nye storagenoder, mislykkes den.

Resolution

Kontrollér netværksforbindelsen mellem alle noder på Avamar-kilden og alle noder på målsystemet.
