put into use.
There are three files in /var/adm/ras that are part of the errlog process
-rw-r--r-- 1 bin bin 197206 Apr 20 09:33 codepoint.cat

sometimes if something is really corrupt you can restore them from a mksysb
and then do an errclear...
You can also run errpt -a >> /myerrorlog
then errclear 0
and the log is empty and you still have a copy of the errpt...
You didn't say why you wanted a new log?
I am not sure but I believe if you have no errorlog file when the system is rebooted it is recreated....... but not 100% sure.........
