NetBackup - Browse and select Virtual Machine time out
NetBackup ile VMware üzerindeki sanal makinelerin imajını alma için oluşturduğumuz politikanın içerisinde Client tabından yeni sanal makine eklemek istediğimizde time out hatası alabiliriz.
Bu durum VMware backup makinesinin sanal makinenin ip adreslerini çözmeye çalışması ve zaman aşımına uğramasından kaynaklanmaktadır.
Registry'e eklenecek bir kayıt ile ip çözümleme işlemi devredışı bırakılarak time out sorunu giderilebilmektedir.
HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\NetBackup\CurrentVersion\Config\BACKUP\disableIPResolution
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 7.0 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.
A hotfix is available for use in those environments where NetBackup can be instructed not to attempt IP resolution. Please contact Symantec Technical Support and quote this TechNote number and defect e-track ET2005798 for the hotfix.
Once the hotfix is applied, 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.
*Note: This hotfix made it into 7.0.1 as per the 7.0.1 Release Notes, page 128. Therefore, if already at 7.0.1, no need to request the hotfix, the following registry value can be set to disable IP resolution attempts for virtual machines.
HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\NetBackup\CurrentVersion\Config\BACKUP\disableIPResolution
