If you run the vxgetcore command without any options, it selects the first core file it finds. This file is usually the latest core file in a list of expected core file locations - starting with the present working directory. If vxgetcore finds more than one binary that matches the core file, it prompts you to select one binary file from the list and enter the full path.
Before you run vxgetcore, contact Symantec Technical Support and get a case ID for your issue. You'll need to include the case ID in the tar file name before you send it to Symantec.
To let vxgetcore prompt you for binary file information
# /opt/VRTSspt/vxgetcore/vxgetcore [-C Symantec_case_ID]
vxgetcore gathers the core file, binary file, library file, and any other available debugging information. It creates a tar file in this format:
/tmp/VRTSgetcore.xxxx/coreinfo.CASEID.hostname.date_time_.gz
