First I would like to say thanks to all the responders. They came in fast
and hard! I might just have to use this resource more often :)

Most said the same thing:

Here was the problem:

> Having a problem creating swap space. It all started when I was
> Sol 2.6. When it asked for partition info I put one of the partitions as
> /swap instead of swap. It created /swap ufs instead of tempfs. Now I
> have any swap space.

Most responses went along these lines:

>Just edit /etc/vfstab and change the line with "/swap" from something like

>/dev/dsk/c0t0d0s1 /dev/rdsk/c0t0d0s1 /swap ufs .........

>to this:

>/dev/dsk/c0t0d0s1 - - swap - no -

I then renamed /tmp to /tmp.old and created a new /tmp directory, rebooted
and all was fine. I then removed /tmp.old. Don't forget to add the sticky
bit to the new /tmp and chmod 777.

A few suggested making a swap file with:

># mkfile 128m /[swapfile]
># swap -a /[swapfile]

I choose to try the vfstab method and it worked. I already knew about
making a swapfile, I was just determinded to find a way to make the swap
space work like I originally intended.

Lesson learned:

Watch what you put in the partition info during Solaris install, putting
"/swap" as a partition instead of "swap" screwed things up and delayed me 12
hours on this machine.
