NetWorker: i backup di vProxy non riescono con l'errore "Unable to backup virtual disk "Hard disk 1"

L'integrazione NetWorker VMware Protection è configurata con l'appliance vProxy. Il backup di una macchina virtuale non viene completato nell'ambiente. Il messaggio di NetWorker Management Console indica che si tratta di unable to backup virtual disk "Hard disk 1."

Per rimuovere dischi aggiuntivi collegati a vProxy, consultare l'articolo della KB 00022590 NVP-vProxy: come utilizzare lo strumento per il controllo integrità ProxyHC sull'appliance vProxy (in inglese).

Il file vbackupd-engine.log di vProxy e il registro di backup del server NetWorker mostrano:

Il vProxy non è in grado di connettersi all'host ESXi di destinazione utilizzando la porta 902. Il flusso di lavoro di backup di vProxy utilizza i comandi VMware Virtual Disk Development Kit (VDDK) per connettersi ai file vmdk , utilizzando hotadd oppure nbd, per eseguire il backup.

Assicurarsi che vProxy sia in grado di connettersi all'host ESXi utilizzando le porte richieste (443 e 902). La tabella "Requisiti delle porte" nella Guida all'integrazione di Dell NetWorker e VMware contiene dettagli e informazioni aggiornate sulle porte richieste per la soluzione.
