NetBackup™ Troubleshooting Guide

Step 1

Enable debug logs.

Enable the appropriate debug logs on the primary server.

For information on logging, see the NetBackup Logging Reference Guide.

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.

Step 2

Configure a test policy.

Configure a test policy to use a basic disk storage unit.

Or, configure a test policy and set the backup window to be open while you test. Name the primary server as the client and a storage unit that is on the primary 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.

Step 3

Verify the daemons and services.

Step 4

Backup and restore a policy.

Start a manual backup of a policy. Then, restore the backup.

Step 5

Check for failure.

If a failure occurs, check the job's Detailed Status in the Activity Monitor.

You can also try the NetBackup All Log Entries report. For the failures that relate to drives or media, verify that the drive is in an UP state and that the hardware functions.

To isolate the problem further, use the debug logs.

For an overview of the sequence of processing, see the information on backup processes and restore processes in the NetBackup Logging Reference Guide.

Step 6

Consult information besides the debug logs.

See the vendor manuals for information on hardware failures.

Step 7

Verify robotic drives.

If you use a robot and the configuration is an initial configuration, verify that the robotic drive is configured correctly.

On a UNIX NetBackup server, you can verify only the Media and Device Management part of the configuration. To verify, use the tpreq command to request a media mount. Verify that the mount completes and check the drive on which the media was mounted. Repeat the process until the media is mounted and unmounted on each drive from the host where the problem occurred. If this works, the problem is probably with the policy or the storage unit configuration. When you are done, tpunmount the media.

Step 8

Include a robot in the test policy.

If you previously configured a nonrobotic drive and your system includes a robot, change your test policy now to specify a robot. Add a volume to the robot. The volume must be in the NetBackup volume pool on the EMM database host for the robot.

Return to step 3 and repeat this procedure for the robot. This procedure verifies that NetBackup can find the volume, mount it, and use the robotic drive.

Step 9

Use the robotic test utilities.

If you have difficulties with the robot, try the test utilities.

Do not use the Robotic Test Utilities when backups or restores are active. These utilities prevent the corresponding robotic processes from performing robotic actions, such as loading and unloading media. The result is that it can cause media mount timeouts and prevent other robotic operations like robotic inventory and inject or eject from working.

Step 10

Enhance the test policy.

Add a user schedule to your test policy (the backup window must be open while you test). Use a storage unit and media that was verified in previous steps.

Step 11

Backup and restore a file.

Start a user backup and restore of a file by using the client-user interface on the primary server. Monitor the status and the progress log for the operation. If successful, this operation verifies that the client software is functional on the primary server.

If a failure occurs, check the NetBackup All Log Entries report. To isolate the problem further, check the appropriate debug logs from the following list.

On a UNIX system, the debug logs are in the /usr/openv/netbackup/logs/ directory. On a Windows computer, the debug logs are in the install_path\NetBackup\logs\ directory.

Explanations about which logs apply to specific client types are available.

For information on logging, see the NetBackup Logging Reference Guide.

Step 12

Reconfigure the test policy.

Reconfigure your test policy to name a client that is located elsewhere in the network. Use a storage unit and media that has been verified in previous steps. If necessary, install the NetBackup client software.

Step 13

Create debug log directories.

Explanations about which logs apply to specific client types are available.

For information on logging, see the NetBackup Logging Reference Guide.

Step 14

Verify communication between the client and the primary server.

Perform a user backup and then a restore from the client that is specified in step 8. These actions verify communications between the client and the primary server, and NetBackup software on the client.

If an error occurs, check the job's Detailed Status in the Activity Monitor.

check the All Log Entries report and the debug logs that you created in the previous step. A likely cause for errors is a communications problem between the server and the client.

Step 15

Test other clients or storage units.

When the test policy operates satisfactorily, repeat specific steps as necessary to verify other clients and storage units.

Step 16

Test the remaining policies and schedules.

When all clients and storage units are functional, test the remaining policies and schedules that use storage units on the primary server. If a scheduled backup fails, check the All Log Entries report for errors. Then follow the recommended actions as is part of the error status code.
