Repeat from before:  you don't need to use clvm just to get names.  You make
some udev rules that correlate the unique scsi id of your array to some
name that you like.  For instance:

$ cat /etc/udev/rules.d/69-xraid.rules 
# /etc/udev/rules.d/69-xraid.rules
# 2008-01-18
# Brian Kroth
# Setup devices nodes for the two storage arrays based upon their unique
# scsi_id

ACTION!="add", GOTO="xraid_end"

KERNEL=="sd*[!0-9]", ENV{ID_SERIAL}=="3600039300001e6db01000000d52b0606",
SYMLINK+="xraid-c1-a1"
KERNEL=="sd*[!0-9]", ENV{ID_SERIAL}=="3600039300001e6db020000006a95fef7",
SYMLINK+="xraid-c1-a2"

KERNEL=="sd*[0-9]", ENV{ID_SERIAL}=="3600039300001e6db01000000d52b0606",
SYMLINK+="xraid-c1-a1-p%n"
KERNEL=="sd*[0-9]", ENV{ID_SERIAL}=="3600039300001e6db020000006a95fef7",
