If a kernel zone process terminates abruptly, the resulting core file is saved on the kernel zone in a location defined by the dumpadm command.
A kernel zone may sometimes crash in conditions that prevent a core dump from generating within the kernel zone. To ensure that in such cases kernel zone core dumps are generated and accessible, use the coreadm command in the global zone to enable and to specify a location for these core dumps.
Refer to the dumpadm and coreadm man pages for additional information.
