The MIB for block side for VNX is already installed on both sp's
Lets you enable or disable processing of SNMP MIB requests.

SNMP community :Name for the SNMP transaction with a remote system. This is used as a password to control access to the
SNMP MIB. Lets you change the name of the group SNMP community that includes devices and management stations that are running SNMP.
as far as I was able to check MIB object tree implamentation is quite poor. Performed an snmpwalk on a VNX 5500 block (Flare 05.31): only some SNMPv2-MIB, IF-MIB and IP-MIB relate objects but no info on disks, raid groups, LUNs, storage groups, temperature, power .....
Maybe SNMP is not the right way to monitor a VNX.
The post Geraldo is pointing to ONLY talks about SNMP traps sent from the control station – see the Event and Notifications on VNX manual.
This has little relevance for the MIB’s used for SNMP get from CS, DM or SP
In fact the snmpd on the CS isn’t even used to send these traps – its nas_snmptrap
Where to find the MIB’s
for VNX block (SNMP on the storage processor)
there also also a dozen values from the Fibre Alliance MIB (FCMGMT-MIB 220.127.116.11.3.94) implemented
for VNX file (SNMP on the data mover)
located in /nas/sys/emccelerra.mib
for the control station (not enabled by default)
see the standard Linux snmpd config files
MIB definitions in /usr/share/snmp/mibs
For anything else that’s not covered in the MIB’s I recommend taking a look at VNX M&R for monitoring instead
