Symptoms

已發現所有 esxi 主機都位於個別的備份 VLAN 和管理 VLAN 上。 
 

vProxy 備份失敗，並出現下列錯誤，如 NetWorker 伺服器上的備份記錄所示：

Cause

發現 vProxy 只會備份與自身位於相同 esxi 主機上的 VM。如果 vProxy 嘗試備份位於個別 esxi 主機上的虛擬機器，將無法透過連接埠 902 連線，如下所示：
  
Could not connect to ESX host esxi_hostname: Failed to connect to server esxi_hostname:902.

Testing connectivity from the vProxy to the esxi host in question using the below command, hangs, and eventually fails to connect, though ping and nslookup, return expected results. 

#curl -kv esxi_hostname:902

Verified the firewall is down on the esxi hosts.

esxcli network firewall set -e false

Verified no layer2 firewall exists, or any firewall between the esxi hosts. 
 

Resolution

發現，esxi 主機都在不同的備份/管理 VLAN 上，無法透過連接埠 902 進行通訊。需要能夠透過連接埠 902 在 esxi 主機和 vproxy 之間進行通訊。
