The following are other possible causes of this error caused by network connectivity issues or a required process such as pbx_exchange not running.

• nbjm is unable to connect to bpcd on the media server

• nbpem is unable to connect to nbproxy

• bptm on the media server is unable to connect to nbjm on the master server.

• You cannot perform an immediate backup operation.

• Verify that bpcompatd, vnetd, and Private Branch Exchange (PBX) are running. Information on how to start PBX is available.

  See "Resolving PBX problems" in the NetBackup Troubleshooting Guide.

• If necessary, stop and restart NetBackup.

  • On UNIX systems, enter the following:

    /usr/openv/netbackup/bin/bp.kill_all
    /usr/openv/netbackup/bin/bp.start_all

  • On Windows systems, enter the following:

    install_path\NetBackup\bin\bpdown
    install_path\NetBackup\bin\bpup

• The following information applies only to a UNIX or Linux NetBackup master server:

  Verify that the bprd and the bpdbm processes are running. If these processes are not running, start them. On a Windows master server, verify that the NetBackup Request Manager and the NetBackup Database Manager services are running. If these services are not running, start them.

  If these processes or services are running, examine the All Log Entries report for the time of the failure to determine where the failure occurred.

  Do one of the following:

  • If you cannot view the report or you get a cannot connect on socket error, verify again that the NetBackup Database Manager service or daemon is running. Then, create a debug log directory for bpdbm, retry the operation, and check the resulting debug log.

  • If you view the report and do not find a problem-related entry, create the debug log directories for the related processes that were running when the error first appeared. (This process frequently is bpbrm.) Then, retry the operation and check the resulting debug logs.

• Verify that the server list specifies the correct master server.

  • The following information applies only to Windows systems:

    The master server is designated in the Server to use for backups and restores drop-down in the Specify NetBackup Machines and Policy Type dialog box. To display this dialog box, start the Backup, Archive, and Restore interface and click Specify NetBackup Machines and Policy Type on the File menu.

  • The following information applies only to UNIX and Linux systems:

    The master server is the first SERVER entry in the bp.conf file.

  • Check the Veritas Technical Support website to ensure that all recommended NetBackup patches are installed.

  • If failure occurs when you run a user-directed backup from a client, make sure that a user-directed backup schedule exists at the master server.

  • With NetBackup database extensions:

    Make sure that the applicable database product has the correct permissions allowing NetBackup to write to the progress log on the client.

  • The following information applies only to UNIX systems:

    If bpdbm has quit when the shutdown script runs on a media server, carefully read the K77netbackup script. It contains details on how to prevent this problem. The script is in /usr/openv/netbackup/bin/goodies.

  If you change the server list on a UNIX or Linux master server, do the following for the changes to take effect: Stop and then restart the NetBackup Request Daemon (bprd) and NetBackup Database Manager Daemon (bpdbm). On Windows, stop and restart the NetBackup Request Manager and NetBackup Database Manager services.

• Check the services file.

  • The following information applies only to UNIX systems:

    Verify that the /etc/services file (and NIS services if NIS is used) has entries for the NetBackup services: bpcd, bpdbm, and bprd.

  On Windows, verify that the %SystemRoot%\system32\drivers\etc\services file has the correct entries for bpcd, bpdbm, and bprd.

  Also, verify that the following numbers match the settings in the services file: The NetBackup Client Service Port and the NetBackup Request Service Port on the Network tab in the NetBackup Client Properties dialog box. To display this dialog box, start the Backup, Archive, and Restore interface and click NetBackup Client Properties on the File menu. The values on the Network tab are written to the services file when the NetBackup Client service starts.

  See Verifying host names and service entries in NetBackup in the NetBackup Troubleshooting Guide.

• On Sun Solaris, verify that all operating system patches are installed

  See the Operating Notes section of the NetBackup Release Notes.

• On Windows, verify that the recommended service packs are installed.

• When the base NetBackup license key expires, daemons (such as bprd and bpdbm) terminate on the NetBackup server. If these daemons are not running, you are likely to encounter status code 25 errors in the Administration console. Install a valid base NetBackup license key, restart the daemons, and restart the console.

• For NetBackup Snapshot Client, the following applies: When many devices are configured on a media server, it may take a long time for the bptpcinfo command to generate the file 3pc. When the backup is run for the first time, the backup may fail with status 25. Make sure that the /usr/openv/volmgr/database/3pc.conf file exists. If it does, rerun the backup. If the backup fails again, run the bptpcinfo manually to generate the file 3pc, then try the backup again.

• In the Auto Image Replication (A.I.R.) scenario, the error can occur if insecure communication is disabled in NetBackup after the trust relationship between the 8.1 and 8.0 master servers is established. If you want to continue with the host connection, do one of the following:

  • In the NetBackup Administration Console on the master server host, select the Security Management > Global Security > Secure Communication > Enable insecure communication with NetBackup 8.0 and earlier hosts option.

  • Specify the nbseccmd -setsecurityconfig -insecurecommunication on command.

• For RHV:

  • Ensure that the RHV credentials are correct and the virtualization server is accessible.

• For VMware:

  • When the VIRTUALIZATION_HOSTS_SECURE_CONNECT_ENABLED option is enabled, you must verify the placement of the certificates and CRLs. Verify whether the VMware virtualization servers' (vCenter, ESX, ESXi) certificates and CRLs are added to the respective ECA configured trust store and the CRL path.

  • Ensure that the certificates and the CRL files are in the correct format and the trust store file and the CRL files are not corrupted.

  • Only the PEM certificate format for file-based trust store & Windows trust store are supported for virtualization servers. P7b or DER format file based trust store is not supported. When this feature is enabled, the certificate ECA store should either be Windows certificate store or file based PEM format store.

• For Nutanix AHV:

  • Ensure that the CA certificate is added to the NetBackup trust store. Refer to the Nutanix AHV Administrator's Guide for more details.
