Errors when adding VMware servers

Table: Errors adding VMware servers

Error message or cause

Explanation and recommended action

Virtualization server credential validation fails.

This error occurs when the NetBackup master server is in a DNAT or a similar setup can access only a few specified NetBackup hosts (PROXY_SERVERS).

The credentials validation occurs in the following order:

  • The auto-discovered discovery host is used to access the virtualization server.

  • If the autodiscovery does not find any information about the virtualization server on the discovery host, the NetBackup master server is used.

Workaround: When you add the virtualization server credentials, select the proxy server that has access to the virtualization server as the backup host for validation.

Note:

Adding or updating VMware credentials also automatically starts the discovery of the VMware server. When backup host information is provided in the request, it is used to perform validation of credentials as well as for performing the discovery. For discovery, NetBackup 8.1.2 is the minimum version that is supported for a NetBackup media server or client that serves as a backup host. For older versions, backup host credential validation succeeds, but the discovery of VMware servers fails.

Unable to obtain the list of trusted Certificate Authorities.

This error might occur when VMware server credentials are added, updated, or validated. It occurs if the environment is configured to enabled communication between NetBackup (master server, media server, or client) and vCenter, ESX, or any other VMware entity using authenticated certificates.

Workaround: Ensure that certificates are installed and are valid.
