Ensure that the Veritas Product Authentication Service is installed and configured.

For complete installation instructions, see the NetBackup Security and Encryption Guide.

Check that both parties have a valid certificate by examining the listed expiry date from the bpnbat -WhoAmI command. For example:

bpnbat -WhoAmI
Name: JDOG
Domain: MYCOMPANY
Issued by: /CN=broker/OU=root@machine1.mycompany.com/O=vx
Expiry Date: Sep 19 12:51:55 2009 GMT
Authentication method: Microsoft Windows
Operation completed successfully.

Shows an expiry date of September 19th, 2009. After 12:51:55 GMT, this credential is no longer valid and a new credential is required.

If you run from the NetBackup Administration Console, close and reopen the console. The console automatically obtains a credential for the currently logged in identity, if possible. By default, these certificates are valid for 24 hours. The following is an example of how to extend the credential beyond 24 hours to 30 days (2592000 seconds):

# vssat setexpiryintervals -p <plugin_name> -t <user> -e 2592000

Ensure that the certificates for both sides either use the same broker, are children of the same root broker, or have trusts established between them.

More information is available on broker hierarchies and how to establish trust relationships between brokers.

See the NetBackup Security and Encryption Guide.

Ensure that connectivity is possible between the physical systems in question. If general sockets cannot connect between the machines (such as ping and telnet), network issues unrelated to NetBackup may be the cause of this problem.

Ensure that the system has sufficient swap space and that the following directories are not full:
