mksysb restore ( vgs on SAN disks)

I have my application vendor looking at this but I want to do my own investigation.

I restored from mksysb and I see my vgs that contain my internal disks.
But I do not see my vgs that contain disks from the SAN. This scares me ..
{{ Ha, ha!! My AIX expert boss just told me I have nothing to worry about. That the vg info is still in there. That I will have to go reimport the VGS.}}

I thought the info would be in the ODM (Vgs, PVID , etc)
My boss is an AIX freaking expert. He is two levels above me. So I didn't want to bother him.

So I will let the vendor walk me through it.

So, no replies necessary.
