FA MIB 2.2 SNMP Behavior
The FA2.2 MIB objects are in compliance with the Fibre Alliance MIB v2.2
Specification (FA MIB2.2 Spec). For a full description of this MIB, go to:
http://www.fibrealliance.org/fb/mib/mib2_2.htm
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” on page 245.
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), and a "sensor" in the sensor
table.
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 It has been replaced by an ability to configure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.
