Problem

Browsing vSphere inventory via clients tab in backup policy could be slow if VMware backup host cannot resolve IP addresses of virtual machines.

Solution

NetBackup 7.x and later for VMware lets users browse VMware vSphere inventory and select virtual machines. If refresh button in GUI is used, it might take a long time for the refresh to complete if the VMware backup host cannot resolve the IP addresses of virtual machines.
 
 The following registry value needs to be set to disable IP resolution attempts for virtual machines.
 
  HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\NetBackup\CurrentVersion\Config\BACKUP\disableIPResolution
 

 If the key BACKUP does not exist please create Key ' BACKUP' under ' Config'. Then create a New -> DWORD Value (32 bits) -> disableIPResolution, under Key ' BACKUP.
 
 
 
  HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\NetBackup\CurrentVersion\Config\BACKUP\disableIPResolution
 
 
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
 

 
**Note: Once disableIPResolution is set, it is recommended that the policies use display name or UUID of the virtual machines in the client tab. If hostname is chosen, NetBackup will use the IP address of the virtual machine as the hostname because IP resolution is disabled. Use of IP address as hostnames in backup policies is not recommended in DHCP environments.
