| About collecting application and daemon core data for debugging | ||

| Prev | Introduction | Next |
If a Storage Foundation application or daemon encounters a problem, it may produce a core file. The vxgetcore script lets you efficiently collect the core file, binary file, library files, and any related debugging information and generate a tar file. You can then send the tar file to Veritas Technical Support for analysis.
You can run vxgetcore in the following ways:
The easiest way to run vxgetcore is with the -a (auto-find) option. You do not need to know the location of the core file or related data. vxgetcore locates the latest core file in the current directory. If there is no core file in the current directory, vxgetcore searches for a list of probable directories.
See Letting vxgetcore find debugging data automatically (the easiest method).
If you know the path to the core file (and optionally the binary file), you can specify them on the command line.
See Running vxgetcore when you know the location of the core file.
You can run vxgetcore without any options, and the script prompts you for all the information it needs.
When you work with vxgetcore, keep in mind the following:
vxgetcore is contained in the VRTSspt support package, which is a collection of tools to analyze and troubleshoot systems. When you install VRTSspt, the vxgetcore script is installed on the path /opt/VRTSspt/vxgetcore/.
Before you run vxgetcore, contact Veritas Technical Support and get a case ID for your issue.
If you know the case number before you run the script, you can specify it on the command line. Getting the case ID first saves you time later. When you send the tar file to Veritas for analysis, the tar file name includes a case number. This approach is faster than generating the file, getting the case ID, and renaming the file later.
You do not have to analyze or work with the tar file vxgetcore generates.
Make sure that the file name includes the case ID, and FTP the file to your local FTP site.
