NetBackup 4.5 Troubleshooting Guide for Windows
General Test and Troubleshooting Procedures
Explanation: A drive has been detected without the expected compression device file
used to configure that device. Automatic device configuration attempts to use a device file
that supports hardware data compression. When multiple compression device files exist
for a drive, automatic device configuration cannot determine which compression device
file is best. It uses a non-compression device file instead.
Recommended Action: If you do not need hardware data compression, no action is
necessary. The drive can be operated without hardware data compression. If you need
hardware data compression, refer to the chapter for your system type in the Media Manager
Device Configuration Guide for UNIX for information on configuring tape drives.
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. 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.
To Test Master Server and Clients
1. Enable appropriate debug logs on the master server (see the “Using the Logs and
Reports” chapter). If you do not know which logs apply, enable them all until you
solve the problem. Delete the debug log directories when you have resolved the
problem.
2. Configure a test policy (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.
3. Verify that the NetBackup services are running on the master server:
