General Test and Troubleshooting Procedures
18 NetBackup Troubleshooting Guide - UNIX
Explanation: A device has been detected without the corresponding device file necessary
to configure that device.
Recommended Action: Refer to the chapter for your system type in the Media Manager
Device Configuration Guide - UNIX for information on creating device files.
Message: Unable to determine drive type
Explanation: The drive is not recognized by NetBackup BusinesServer. The drive cannot
be auto-configured.
Recommended Action: Configure the drive manually.
General Test and Troubleshooting Procedures
If the “Preliminary Troubleshooting” or “Troubleshooting Installation and Configuration
Problems” procedures did not reveal the problem, perform the following procedures,
skipping those steps that you have already performed.
The procedures assume that the software was successfully installed, but not necessarily
configured correctly. If NetBackup or Media Manager has never worked properly, there
are probably configuration problems. Repeat the checks mentioned in the
“Troubleshooting Installation and Configuration Problems” procedure when you
encounter errors. In particular, look for device configuration problems.
You may also want to perform each backup and restore twice. On UNIX, perform them
first as a root user and then as a nonroot user. On Windows NT/2000, perform them first
as a user that is a member of the Administrators group and then as a user that is not a
member of the Administrator group. In all cases, ensure that you have read and write
permissions on the test files.
The explanations in these procedures assume that you are familiar with the information in
Appendix A. If you have not read that appendix, do so before proceeding.
To Test Master Server and Clients
1. Enable appropriate activity and debug logs on the master server (see Chapter 3). If
you do not know which logs apply, enable them all until you solve the problem.
Delete the activity log directories when you have resolved the problem.
2. Configure a test class (set backup window to be open while you are testing). Name the
master server as the client and a storage unit that is on the master server (preferably a
nonrobotic drive). Also, configure a volume in the NetBackup volume pool and insert
the volume in the drive. If you don’t label the volume by using the bplabel
command, NetBackup automatically assigns a previously unused media ID.
