Disable Re-scan of HBA Adapters During Incremental Backup

Applicable to VMware ESX

Applicable only to UDP v6.5, does not apply to v6.5 Updates.

Symptom

When the source node and the proxy server are in different VMware ESX servers, and I run an Incremental backup, my backup takes a longer time to run. I also receive multiple rescan messages. I want to disable the rescanning of all host bus adapter (hba) of other VMware ESX servers during Incremental backups.

Solution

You can disable the scan by creating a registry key in the proxy server and assigning a value to it.

Follow these steps:

  1. Log in to the machine.
  2. Navigate to the following folder:

    3. HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine

  3. Create the following registry key (DWORD), if it is not already created

    4. DisableAllESXNodeRescan

  4. Set the value of the registry key to 1.
