Same problem here.
I just downloaded the latest filer mib from here http://mysupport.netapp.com/NOW/download/tools/mib/, looked at the "traps.dat" file for "miscGlobalStatus" which says it's ".220.127.116.11.4.1.718.104.22.168.4.0" but that OID just doesn't exist.
Just wondered if anyone had any updates on this issue (v8.3 cDOT), I have checked the netapp traps.dat and mib files from the support site and they show the OID for GlobalStatus
miscGlobalStatus snmp.22.214.171.124.4.1.7126.96.36.199.4.0miscGlobalStatusMessage snmp.188.8.131.52.4.1.7184.108.40.206.25.0
However they dont seem to exist
# snmpget -v 1 -c public X.X.X.X .220.127.116.11.4.1.718.104.22.168.4.0Error in packetReason: (noSuchName) There is no such variable name in this MIB.Failed object: SNMPv2-SMI::enterprises.722.214.171.124.4.0
same problem here. Looks like SNMP on NetApp is dead.
