Enterprise traps
Traps can be generated in response to events occurring in the storage system. These events can be selected by severity and by
individual event type. A maximum of three SNMP trap destinations can be configured by IP address.
Enterprise event severities are informational, minor, major, and critical. There is a different trap type for each of these
severities. The trap format is represented by the enterprise traps MIB. Information included is the event ID, the event code
type, and a text description generated from the internal event. Equivalent information can also be sent using email or popup
alerts to users who are logged in to the PowerVault Manager.
FA MIB 2.2 SNMP behavior
The FA MIB 2.2 objects are in compliance with the FibreAlliance MIB v2.2 Specification (FA MIB2.2 Spec).
FA MIB 2.2 was never formally adopted as a standard, but it is widely implemented and contains many elements useful for
storage products. This MIB generally does not reference and integrate with other standard SNMP information. It is implemented
under the experimental subtree.
Significant status within the device includes such elements as its temperature and power sensors, the health of its storage
elements such as virtual disks, and the failure of any redundant component including an I/O controller. While sensors can be
individually queried, for the benefit of network management systems all the above elements are combined into an overall status
sensor. This is available as the unit status (connUnitStatus for the only unit).
The revisions of the various components within the device can be requested through SNMP.
The port section is only relevant to products with Fibre Channel host ports.
The event table allows 400 recently-generated events to be requested. Informational, minor, major, or critical event types
can be selected. Whichever type is selected enables the capture of that type and more severe events. This mechanism is
independent of the assignment of events to be generated into traps.
The traps section is not supported. It has been replaced by an ability to configure trap destinations using the CLI or the
PowerVault Manager. The statistics section is not implemented.
The following table lists the MIB objects, their descriptions and the value set in ME4 Series storage systems. Unless specified
otherwise, objects are not settable.
