Missing basic SNMP data for a disk partition on megaraid_sas mount

spec:
CentOS 4
2950 with 1 80 gig SATA and 5 750 GIG SATA drives in a RAID partition.
OMSA NOT installed (it places to much load on the box with what it is
already doing).
all I'm looking for is basic snmp data for the partition created on the
Raid partition.
 
/dev/sda is a single small disk
/dev/sdb is a large raid partition greater then 2 tb.
 
I have stats for all partitions on /dev/sda  (i.e. root, /boot,
/var/log).
 
But nothing for anything on /dev/sdb1.
 
What am I missing?  I don't see that I should need to load the LSI SNMP
agent to get basic disk stats like disk label, space free, etc.
 
This is what I get from a local snmpwalk -c public -v 2c localhost
