Status Codes
1. Check the NetBackup Problems report for clues on why the failure occurred.
2. On a UNIX system, check that /etc/services and NIS services map (if applicable)
have entries for the NetBackup services: bpcd, bpdbm, and bprd.
3. On a Windows NT/2000 system, verify that the
%SystemRoot%\system32\drivers\etc\services file shows the correct
entries for the NetBackup internet processes: bpcd, bpdbm, and bprd.
Ensure that the NetBackup Client Service Port number and NetBackup Request
Service Port number on the Network tab in the NetBackup Configuration dialog box
match the settings in the services file. To display this dialog, start the Backup,
Archive, and Restore interface and click Configure on the Actions menu. The values
on the Network tab are written to the services file when the NetBackup Client
service starts.
Also, see “Verifying Host Names and Services Entries” on page 32.
4. Check the level of network activity. An overloaded network can cause this error.
5. If the above actions do not reveal the problem, create an activity log directory for the
process that returned this status code, retry the operation, and check the resulting
activity log.
Status Code: 20
Message: invalid command parameter
Explanation: One or more command parameters were not valid. This error can occur
when a master and its media servers or a master server and a client have different levels of
NetBackup installed. For example, if a NetBackup master server has NetBackup 3.2 and
the media server has NetBackup 3.0.
This error can also occur if the wrong parameters are used when executing a command
line.
Recommended Action:
1. Check the NetBackup Problems report for clues.
2. If the error occurs when executing a command on the command line, verify that the
parameters are valid.
3. Compare the NetBackup version level on the server to that on the clients:
◆ On UNIX NetBackup servers and clients, check the
/usr/openv/netbackup/bin/version file.
