sysdumpdev -l Shows you dump setup

-P -p /dump_dev *Sets the primary dumpdev (make a volume not Mirror)
-p -s /Dumpdev * Set the Secondary dump Normaly hd6 (paging space )


Dump Messages The messages you are getting is related to the space where the dump file is copied

eg /var/adm/ras

So when /var is running low on space you will have this messages on your system every day at about 3pm

What to do
  1. Add more space to /var ( chfs -a size=xxxxxx /var (where xxx new size )
  2. have a look in /var/preserve and rmove old junk ( this folder is related to vi -r files )
  3. clean out the /var/adm/wtmp file and make it smaller ( nulladm command is used for this )

wtmpx

utmpx(4)							   File Formats 							  utmpx(4)

NAME

       utmpx, wtmpx - utmpx and wtmpx database entry formats

SYNOPSIS

       #include <utmpx.h>
       /var/adm/utmpx
       /var/adm/wtmpx

DESCRIPTION

       The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files.

       The  utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database
       contains the history of user access and accounting information for the  utmpx database.

USAGE

       Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to  inter-
       act with the utmpx and wtmpx databases to ensure that they are maintained consistently.

FILES

       /var/adm/utmpx	       user access and adminstration information

       /var/adm/wtmpx	       history of user access and adminstrative information

SEE ALSO

       getutxent(3C), wait(3C)wait.h(3HEAD)
