thats the file the dump is copied to at (re-)boottime

you dump-device must be a lv (or nfs-dir)

see sysdumpdev -l

my dump device dumps to a file in /var/adm/ras, not paging device.

What about the thinking that "paging space should be = to total memory
in the event of a system dump."

That is something I am hearing at my assignment now. Not something I
practice, but they are talking about it.

So less than 1GB, use the old formula, >1GB, make it half real memory?

IBM support told me to make my Total Page Space half of the total Real

Subject: paging space
Hi,
What's the current accepted standard for configuring paging space?
According to my 4.3 System Administration Redbook:
Total paging space = 512MB + (memory size -256MB) * 1.25MB
but I seem to recall reading this is significantly out of date for newer
servers.  Any suggestions?
