NetBackup status codes

NetBackup provides status codes to help you understand and troubleshoot issues that can occur.

For information about NetBackup status codes, refer to the NetBackup Status Codes Reference Guide.

Table: Status codes related to NetBackup for AHV

Ensure the certificate is generated with the correct host name. The certificate is issued on the Fully Qualified Domain Name of the cluster. Therefore, when you create a BigData policy, provide the same Fully Qualified Domain Name in the Application_Server parameter. The Acropolis cluster name cannot use the short name of the cluster, as it will not match the Fully Qualified Domain Name in the SSL certificate. See Managing SSL certificates .
When the mount operation fails with the following message in the `nbaapidiscv` process logs: status_code aapi_logmsg: session_id:xxxx_ Nutanix Plugin :Failed to mount :/user/.acropolis/snapshot/containerID/vmdisk; Error: Permission denied.

The status code provides you with a problem statement and a recommended action to resolve the issue. Backup of the virtual machines that have volume groups attached is not supported.
When the following status code is displayed: Error code 223: an invalid entry was encountered	Ensure that you have provided valid credentials to access the Nutanix Acropolis cluster.
When the following status code is displayed: Status code 6654: Unable to retrieve the credentials for the server.	This error can occur if you have not configured the Nutanix Acropolis cluster credentials on the NetBackup master server. This error can also occur if the backup host is unable to access NetBackup and retrieve the cluster credentials. See Adding the Nutanix Acropolis Cluster credentials for NetBackup. See Adding a backup host to the NetBackup master access list.
