The default location for AIX crash dump is at /var/adm/ras with the name "vmcore.#.bz"
# represents the sequence number of the crash dump.
# sysdumpstart -p : Command to initiate a system dump and dump the crash in the primary dump device.
But the user initiated dump will not be stored in /var/adm/ras directory. To do so, We need execute the # savecore -d.
# savecore -d : Command copies the latest dump to the /var/adm/ras directory.
# sysdumpdev -t : Command to get the latest dump device name and its size.
