SNMP reference
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: 
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 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 It has been replaced by an ability to configure trap destinations using 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.
The following table lists the MIB objects, their descriptions and the value set in an 2000 G2 Modular 
Smart Array storage system. Unless specified otherwise, objects are not settable.

SystemURL
Top-level URL of the device; for 
example, http://10.1.2.3. If a 
web server is not present on the 
device, this string is empty in

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.

sysuptime
 timestamp of the last
