14.4 The 3PAR SNMP Agent
The 3PAR SNMP agent runs on the InServ Storage Server and provides a management interface
to enable other software products to manage 3PAR hardware using SNMP. The 3PAR SNMP
agent responds to GET, SET, GETNEXT, and GETBULK SNMP requests and also generates
notification messages (traps) for critical events (alerts) and alert state changes. The SNMP
agent converts all system alerts and alert state changes into SNMPv2 traps and forwards them
to all SNMP management stations that have previously registered with the agent. These
notifications contain detailed information describing critical events and are generated for
every alert and alert state change issued by the InServ Storage Server. The exact message
formats are described in the 3PAR MIB. See Chapter 14, Using SNMP, in the InForm OS CLI
Administrator’s Manual for instructions on locating this file.
14.4.1 Standard Compliance
The 3PAR SNMP agent supports the following standards:
■ SNMPv2c
This version refers to a widely used administrative framework for SNMPv2, also known as
“community-based SNMPv2.” Although this version includes SNMPv2 enhancements like
notification and GETBULK requests, it still relies on the SNMPv1 community concept for
security.
■ Standard Management Interface-v2 (SMIv2)
This standard specifies the format of the MIB. The 3PAR MIB definition uses SMIv2
conventions.
