I just wanted to post the solution to this issue:
I had to add the -M1 option to the pvcreate and vgcreate commands to
force them to use LVM1 instead of LVM2.
My golden client has LVM1 logical volumes and for some reason, it was
trying to create LVM2 volumes on the new system. Maybe because my SI
server is RedHat 4 which uses LVM2?

Amanda,
are you trying to use lvm over software raid? In this case have you
already seen the following howto?
http://wiki.sisuite.org/SoftwareRAID#head-8a021864a4988ace0b6ba383018a982dd6f8f103
SystemImager is able to automatically generates the autoinstall script,
so try to modify the autoinstallscript.conf (looking at the howto) and
recreate the script with si_mkautoinstallscript...
Moreover if the root filesystem is on a lvm over raid volume the initrd
in the image must contain both lvm and raid modules.. in the following
output it seems that no raid module is loaded during the boot...

I am using SI 3.6.3 to image a redhat linux machine using raid & lvm.
I added the following to the golden client master script to create the
volume group and logical volumes:
### BEGIN LVM initialization commands -AR- ###
pvcreate -ff -y /dev/sda3
### END LVM initialization commands ###
### BEGIN LVM groups creation commands -AR- ###
vgscan
vgcreate -s 8MB -v Volume00 /dev/sda3
### END LVM groups creation commands ###
### BEGIN LVM volumes creation commands -AR- ###
lvcreate --verbose --size 2.5G --name LogVol00 Volume00
lvcreate --verbose --size 3.0G --name LogVol03 Volume00
lvcreate --verbose --size 1008M --name LogVol05 Volume00
lvcreate --verbose --size 8.0G --name LogVol04 Volume00
lvcreate --verbose --size 5.0G --name LogVol01 Volume00
lvcreate --verbose --size 6.0G --name LogVol02 Volume00
### END LVM volumes creation commands ###
The install process completes (and I see the volume group and logical
volumes being created), but when I reboot, the kernel does not find the
volume group Volume00. Since my root filesystem is on a logical volume,
the server will not boot and I get the following messages:
...
Partition check:

-------------
I tried reimaging with "vgchange -y a" added into the install script
after the vgcreate command, but the volume group was still not found by
the kernel when rebooting.
I would appreciate any suggestions!
Thanks!
