Troubleshooting PBX security

The PBX Secure Mode must be set to false. If Secure Mode is true, NetBackup commands such as bplabel and vmoprcmd do not work. PBX messages similar to the following appear in /opt/VRTSpbx/log (UNIX) or install_path\VxPBX\log (Windows).

   5/12/2008 16:32:17.477 [Error] V-103-11 User MINOV\Administrator
    not authorized to register servers
    5/12/2008 16:32:17.477 [Error] Unauthorized Server

To troubleshoot PBX security

  1. Verify that PBX Secure Mode is set to false (the default):
    • On Windows:

      install_path\VxPBX\bin\pbxcfg -p

    • On UNIX:

      /opt/VRTSpbx/bin/pbxcfg -p
  2. If necessary, set Secure Mode to false by entering the following:

    • On Windows:

      install_path\VxPBX\bin\pbxcfg -d -m
    • On UNIX:

      /opt/VRTSpbx/bin/pbxcfg -d -m
  3. Stop NetBackup:

    • On Windows:

      install_path\NetBackup\bin\bpdown
    • On UNIX:

      /usr/openv/netbackup/bin/bp.kill_all
  4. Stop PBX:

    • On Windows: Go to Start > Run, enter services.msc, and stop the Private Branch Exchange service.

    • On UNIX:

      /opt/VRTSpbx/bin/vxpbx_exchanged stop
  5. Start PBX:

    • On UNIX:

      /opt/VRTSpbx/bin/vxpbx_exchanged start
    • On Windows: Go to Start > Run, enter services.msc, and start the Private Branch Exchange service.

  6. Start NetBackup:

    • On Windows:

      install_path\NetBackup\bin\bpup
    • On UNIX:

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