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 It has been replaced by an ability to configure trap destinations using the CLI or the PowerVault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.

Object Description Value
RevisionNumber
Revision number for this MIB 220
UNumber
Top-level URL of this device, for example,
http://10.1.2.3. If a web server is not
present on the device, this string is empty in
accordance with the FA MIB2.2 Spec.
Default: http://10.0.0.1
StatusChangeTime
sysuptime timestamp of the last status
change event, in centiseconds.
sysuptime starts at 0 when the Storage
Controller boots and keeps track of the up
time. statusChangeTime is updated
each time an event occurs.
0 at startup
ConfigurationChangeTime
sysuptime timestamp of the last
configuration change event, in
centiseconds. sysuptime starts at 0
when the Storage Controller boots and
keeps track of the up time.
configurationChangeTime is updated each
time an event occurs.
0 at startup
ConnUnitTableChangeTime
sysuptime timestamp of the last update
to the connUnitTable (an entry was
either added or deleted), in centiseconds.
0 always (entries are not added to or
deleted from the connUnitTable)
connUnit Table Includes the following objects as specified by the FA MIB2.2 Spec:
