bash-3.00# coreadm -g /globalcore/core.%f.%p -e global
bash-3.00# coreadm -G all -I all
bash-3.00# coreadm

* When system returns:
a. dmesg
b. get a copy of /var/adm/messages and /var/log/syslog
c. get a copy of the system core if a system/kernel panic, from /var/crash and/or the pwd if a process dump
