NetBackup status code: 26

Message: client/server handshaking failed

Explanation: A process on the server encountered an error when it communicated with the client. This error indicates that the client and server were able to initiate communications, but encountered difficulties and the communications did not complete. This problem can occur during a backup or a restore.

This error may also occur during certificate enrollment if the public key infrastructure (PKI) artifacts are not valid. For example: The error may occur if the NetBackup 8.2 or later master server cannot identify the issuer of the host certificate.

Recommended Action: Determine which activity encountered the handshake failure by examining the All Log Entries report for the appropriate time period. Determine the client and server that had the handshake failure.

For detailed troubleshooting information, create a debug log directory for the process that returned this status code. Then retry the operation and review the resulting debug log.

If the error has occurred during the certificate enrollment process, verify the following:

  • Verify the PKI artifacts by running these commands:

    • nbcertcmd -listAllCertificates [-jks] - Run on the master server to display the web server certificate information from Java keystore.

    • nbcertcmd -listCACertDetails -ECA - Run on the host to list the details of the CA certificates that are stored its trust store.

  • Ensure that the issuers of the client and server certificates are available in each other's trust stores.
