Difference in TC and RS

Hi Gurus,

TC - Reset System via Transfer of control
RS - Resets system with RST signal

What is the difference between these 2 kind of resets in a practical scenario?

regards,
Syam

Re: Difference in TC and RS

An RS will just reboot the system. It will restart and go through all of its normal bootup tests.

A TC will also restart the system, BUT it will take much longer because it will create a crash dump. The contents of RAM will initially be written to disk, to your DUMP area as seen with 'lvlnboot -v'. Then the system will reboot. During restart the information in the dump area will be read and compressed and written to /var/adm/crash if you have enough disk space and everything is set up correctly.

TC = Transfer of Control
Which simulates a system panic (for the lack of a better term) and generates a crash dump from the contents of the memory at the time it was issued.

RS = Reset
Sends a reset signal to the Monarch CPU and resets the whole system in a brutal way. No crash dumps are generated. Consider it as a soft form of power down and power back up.

Do you mean the DUMP area? If so, yes it is only used for the crash dump when the machine crashes or you do a TOC.
