Som visas i loggarna har Avamar-källan en enda nod.
Replikeringsjobbet kan ansluta till Avamar-målet med hjälp av IP 10.1.1.30.
Den kan inte nå nio av de noder som presenteras för den i dispatcher-tabellen.
 
  • Målsystemets IP-adress har bekräftats vara korrekt
  • Inloggningsuppgifterna på målet är korrekta

Cause

När Avamar-målet expanderades öppnades inte de nödvändiga brandväggsportarna för att aktivera anslutning till de nya noderna.
När replikeringen ansluter till eventuella ursprungliga lagringsnoder lyckas den.
När replikeringen ansluter till nya lagringsnoder misslyckas den.

Resolution

Kontrollera nätverksanslutningen mellan alla noder på Avamar-källan och alla noder i målsystemet.
