This new version works ok. Thanks!

Yes, definitely. I'm still playing with the configuration and testing of 
this server, and I've deleted and recreated some virtual disks directly from 
OMSA.

I tried restarting the SNMP service on the server, and now I get a more 
usual output from snmpwalk

SNMPv2-SMI::enterprises.674.10893.1.20.140.1.1.1.1 = INTEGER: 1
SNMPv2-SMI::enterprises.674.10893.1.20.140.1.1.1.2 = INTEGER: 2
SNMPv2-SMI::enterprises.674.10893.1.20.140.1.1.2.1 = STRING: "Virtual Disk 
0"
SNMPv2-SMI::enterprises.674.10893.1.20.140.1.1.2.2 = STRING: "DATA"
SNMPv2-SMI::enterprises.674.10893.1.20.140.1.1.3.1 = STRING: "Windows Disk 
0"
SNMPv2-SMI::enterprises.674.10893.1.20.140.1.1.3.2 = STRING: "Windows Disk

Have a nice day
