• Proxyen er forbundet til esx på port 902, men den forsøger at oprette forbindelse til VM-disk mere end én gang, men det mislykkes på grund af netværksproblem (dvs. pakketab) med følgende fejl:   

2015-11-18 09:44:15 avvcbimage Info <16041>: VDDK:DISKLIB-LIB   : Failed to open 'vpxa-nfc://[<Datastore_Name>] <VM_Name>/<VM_Name>.vmdk@<esx_Name>:902' with flags 0x1e NBD_ERR_NETWORK_CONNECT (2338).

 

1. Host VMotion den virtuelle maskine, der ikke kunne sikkerhedskopieres (ovenfor kaldet "VM_Name") til en anden ESX-server.
2. Udfør en on-demand-sikkerhedskopiering af den migrerede virtuelle maskine .
3. Når det er gennemført med succes, skal kunden kontakte deres netværksteam for at kontrollere, hvorfor pakker falder mellem proxyen (omtalt ovenfor som "Proxy_Name") og ESX (kaldet "esx_name").

1. Åbn en kitt til den proxy, der bruges til sikkerhedskopien (dvs. Proxy_Name).
2. Kør nslookup <esx_FQN> kommando.
3. Hvis resultatet er negativt, skal du bede kunden om at ændre esx-posten på DNS eller tilføje hver proxy /etc/hosts-fil med den korrekte esx FQN og IP.
