Credentials for VMware server are not valid
A number of issues can prevent NetBackup from gaining access to the ESX server or vCenter server. When you add credentials for a VMware server, NetBackup validates the credentials.
Problems can result for a variety of reasons, including the following:
Problems with the host name or host IP address.
An incorrect virtual machine server name. Make sure that the server name is entered correctly.
You used a short host name for the server for its NetBackup credentials, and need to replace that name with the fully qualified host name.
Two hosts currently resolve to the same IP address, and one of them must be renamed and assigned a new IP address.
For these situations, delete and re-add the VMware server.
See Add VMware servers.
An invalid username or password. Make sure that a valid username and password were entered correctly.
An incorrect port number. Make sure that the port number is correct in the VMware server credential settings. If the VMware server uses the default port, no port specification is required.
You do not have enough privileges to perform backups or restores. (Note however that lack of sufficient privileges may not cause the credential validation to fail.)
