LVM disk extend after P2V to VMWARE

We have recently P2V'd a physical RHEL 5.8 system to VMware.

FDISK shows the resized disk
Disk /dev/sdb: 214.7 GB, 214748364800 bytes
68 heads, 4 sectors/track, 1542023 cylinders
Units = cylinders of 272 * 512 = 139264 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 1 948737 129028096 8e Linux LVM

But I am unable to resize...
Failed to read physical volume "/dev/sdb"
0 physical volume(s) resized / 0 physical volume(s) not resized

Was wondering if anyone has run into this issue.
Thanks.
