crash dumps

how to check if the crash dumps are created when tc is initiated for the system reboot
Thanks

Have a look at the /etc/rc.config.d/crashconf file. It will tell you what is configured to happen.

thanks for the reply. This is how the crash conf looks like
# CRASHCONF_ENABLED: Configure crash dumps at boot time.
CRASHCONF_ENABLED=1

# For setting the included and excluded page classes and for setting the
# compression mode, use crashconf(1M). See crashconf(1M) for more details.

# CRASHCONF_READ_FSTAB: If set to 1, /etc/fstab will be scanned looking for
# "dump" devices, which will be configured as crash dump
# devices.
CRASHCONF_READ_FSTAB=1


# CRASHCONF_REPLACE: If set to 1, and if CRASHCONF_READ_FSTAB is 1, any dump
# devices in /etc/fstab will override and replace the system's
# current crash dump configuration (usually, the one compiled
# into the kernel). If set to 0, any such setting will be
# *added* to the current settings rather than replacing them.
CRASHCONF_REPLACE=0

So do you still have questions? The above tells me that your system will write crash dumps if the server crashes or is TOC'ed.

The crash dumps should be written to /var/adm/crash by default.

Dear Patrick,
No questions - thank you for your input

you should also check that there is enough room in your dump area of your disk with crashconf
and in /var/adm/crash
