Re: Extend Swap?
My biggest question is why do you think you need to add 7GB more swap space? Your allocation looks fine. You don't appear to be paging out. Why waste 7GB of disk space?

Re: Extend Swap?
According to this swapinfo output, you aren't using swap so what makes you think that you need more swap space?

Re: Extend Swap?
Just make a new lvol.
Is there a specific reason you need that much swap? Your system performance would die before before you ever actually reached 15 GB of swap used.
You do need to have at least one for one swap for memory. psuedo-swap is a help in the area as well, if you have it enabled in the kernel. (swapmem_on=1)

Re: Extend Swap?
I mean, after all, that is what you bought all that RAM for.

Re: Extend Swap?
If you are running more swap space than memory, running pseudoswap (swapmem_on=1) is pointless.

Re: Extend Swap?
I don't know where you are going to create the new SWAP lvol, I mean which disk. If you are trying to create on a external SAN array, try to spend it to multiple spindles as much you can.
my 2 cents
