eight disks were purchased and added to the system as the same time.  I
successfully created a log volume group out of the first four; they are
mounted on /m3team3.

I used parted to create a GPT label on the disks.  Then I used fdisk to
create one partition taking up all the space on the disk.  I then used "mkfs
-t ext3 /dev/sdg1 (etc.) on all the partitions before I used pvcreate,
vgcreate and lgcreate.

The process worked on the first four disks.

Thanks for your help
