Symmetrix uses the FCMGMT MIB. MIB stands for Management Information Base. OID (the entries in the MIB) are Object IDentifiers. In your example the severity is INFO. You can work it out in the following way:  The overview of how the MIB is structured can be found here: [URL]  From here you can see that Object:1.3.6.1.3.94.1.11.1.6 is known as "connUnitEventSeverity". Download the .zip file from the above address and you find:  FcEventSeverity ::= INTEGER { unknown (1), emergency (2), alert (3), critical (4), error (5), warning (6), notify (7), info (8), debug (9), mark (10) -- All messages logged  So... Object:1.3.6.1.3.94.1.11.1.6.80.6.4.130.222.184.230.128.0.0.0.0.0.0.0.0.1 Value:8  translates to INFO in the above table.  
 I am looking to monitor my Symmetrix arrays using the Solutions Enabler storevntd.  I am successfully sending traps to our Network Management System, currently NetCool, but we are not able to set the severity properly.  I'm looking for the OID Tree that is being used so I can validate which OID is for severity and what the severity corresponds to.  Below is an example of what NetCool is receiving from the storevntd.    Enterprise: 1.3.6.1.4.1.1139.3 Object:1.3.6.1.3.94.1.11.1.3.80.6.4.130.222.184.230.128.0.0.0.0.0.0.0.0.1 Value:1 Object:1.3.6.1.3.94.1.11.1.7.80.6.4.130.222.184.230.128.0.0.0.0.0.0.0.0.1 Value:2 Object:1.3.6.1.3.94.1.11.1.8.80.6.4.130.222.184.230.128.0.0.0.0.0.0.0.0.1 Value:0.0 Object:1.3.6.1.3.94.1.11.1.9.80.6.4.130.222.184.230.128.0.0.0.0.0.0.0.0.1 Value:Symmetrix 000192603034 UNKNOWN 15 : Symmetrix External Lock has been acquired.
