The specific commands you need are vgscan and vgchange; access to the>>>>>
logical volume will be through /dev/mapper/yourVGname-yourLVname
(or /dev/yourVGname/yourLVname) and not /dev/sdb* (which is the raw
partition containing a PV).
(Although the context is different, there are some examples of
vgscan/vgchange usage here:

Good afternoon, Chris.
My problem is related but not exactly the same. In my case I have upgraded from FC5 to F9 by doing a fresh install on a new hard drive, and I need to mount the old FC5 boot disk to copy some stuff off of it.
"mount /dev/sdb2 /driveb" doesn't work for the reasons noted (/dev/sdb2 is a container and not a volume).
So, I said "lvm vgscan" and got:
File descriptor 20 left open
Reading all physical volumes. This may take a while...
Found volume group "VolGroup00" using metadata type lvm2
Found volume group "VolGroup00" using metadata type lvm2
Then I said "pvs" and got:
File descriptor 20 left open
PV VG Fmt Attr PSize PFree
/dev/sda2 VolGroup00 lvm2 a- 111.59G 32.00M
/dev/sdb2 VolGroup00 lvm2 a- 76.22G 32.00M
(Hope the formatting and column alignment on the above doesn't come through all screwed up...)
Apparently it thinks that both volumes are named VolGroup00 (instead of ...00 and ...01) so things like lvm vgchange don't do any good because it doesn't know which VolGroup00 to make available.
/dev/mapper contains:
crw-rw---- 1 root root 10, 60 2008-09-22 11:20 control
brw-rw---- 1 root disk 253, 0 2008-09-22 15:20 VolGroup00-LogVol00
brw-rw---- 1 root disk 253, 1 2008-09-22 11:20 VolGroup00-LogVol01
... with no corresponding LogVol00/01 for VolGroup01 (since the system was told that both of the volumes are named VolGroup00).
I've Googled everything I can think of and am out of ideas.
Thanks...
