What does your partition table look like? prtvtoc /dev/rdsk/c0t0d0s2

There is no slice 5 on the disk, that's your problem.

You are showing /dev/rdsk/c0t0d0s2 - the s2 on the end means slice (2) not (5). Change your vstab to read c0t0d0s5 and it should be fine.

No, he was trying to mount the correct slice number. I asked him to do the prtvtoc on slice 2.

The problem is that slice 5 doesn't exist yet. There is quite a lot of unused space on the disk, so nothing preventing it from being created.

He is trying to mount on slice 5, not slice 2, and slice 5 doesn't exist as Annihilannic pointed out.
