Troubleshooting › Jobs Fail with Dagent Errors

Jobs Fail with Dagent Errors

Valid on UNIX and Linux platforms.

Symptom

Backup and restore jobs fail approximately five minutes after they start. One of the following messages appears in the Activity Log:

• Dagent hits error while writing data to media.
• Dagent hits error while starting session.
• Dagent hits error while reading session header.
• Dagent failed to read Session Header, possible error code = [-5]

Solution

In most cases, the hardware from which you are backing up or restoring data is causing the errors to occur. For example, you restarted or reconfigured a library. However, the operating system running on the server connected to the device did not refresh.

To remedy this problem, log in the data mover server and use the operating system commands to ensure that the device is functioning properly.

Example:

mt -t tapename

Optionally, you can reconfigure the device using operating system commands.

Example:

insf -e

Note: The above syntax applies to HP operating systems.
