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). For a full description of this MIB, go to: www.emc.com/microsites/fibrealliance. FA MIB 2.2 is a subset of FA MIB 4.0, which is included with HP System Insight Manager (SIM) and other products. The differences are described in "FA MIB 2.2 and 4.0 differences" (page 156). 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 It has been replaced by an ability to configure trap destinations using the CLI or SMU. The statistics section is not implemented.

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). For a full
description of this MIB, go to:
www.emc.com/microsites/fibrealliance
.
FA MIB 2.2 is a subset of FA MIB 4.0, which is included with HP System Insight Manager (SIM) and other products.
The differences are described in
"FA MIB 2.2 and 4.0 differences" (page 156)
.
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
SMU. The statistics section is not implemented.
The following table lists the MIB objects, their descriptions and the value set in a MSA 1040 storage system. Unless
specified otherwise, objects are
not
settable.
