Using vxgetcore to gather application core dump info for analysis

Problem

A Storage Foundation application has generated a core dump and the customer needs an analysis of the core file.

Error Message

Application has generated a core dump.

Cause

When an application has dumped core, it is necessary to collect not only the "Core" file but also the offending binary as well as the library files for detailed analysis.

Solution

Download and run the vxgetcore script on the system where the Storage Foundation binary dumped core.

# cd /opt/VRTSspt/vxgetcore
# ./vxgetcore

Note:
        ./vxgetcore will attempt to find the correct core
        and/or binary file, but we can not guarantee that it will succeed in
        collecting the right combination of files. If you know their exact locations
        then you may quit now and re-run this utility as follows:

        # ./vxgetcore -c /path/to/corefile -b /path/to/binary

Ex: Collecting had core (core.7607) and its binaries. 

      # /opt/VRTSspt/vxgetcore/vxgetcore -c /var/tmp/core.7607 -b /opt/VRTSvcs/bin/had


        Or, for full usage, see help:
        # ./vxgetcore -h
