SNMP Trap Message Support

Unsolicited SNMP trap messages that indicate director operational state changes

or failure conditions can be customer-configured to be transmitted to up to 12

management workstations. If installed on a dedicated Ethernet LAN, the

workstations communicate directly with each director. If installed on a customer

intranet, workstations communicate with directors through the HAFM appliance.

SNMP data and trap messages are defined in the Fibre Channel FE-MIB

definition, a subset of the TCP/IP MIB-II definition (RFC 1213), and a custom,

director-specific MIB. Customers can install these MIBs (in standard ASN.1

format) on any SNMP management workstation.

Although SNMP trap messages are typically transmitted to customers only, the

messages may be provided to service personnel as initial notification of a director

problem or as information included in the fault isolation process. Generic SNMP

traps include:

■ coldStart—Reports that the SNMP agent is reinitializing due to a director

reset.

■ warmStart—Reports that the SNMP agent is reinitializing due to a director

IPL.

■ authorizationFailure—Reports attempted director access by an unauthorized

SNMP manager. This trap is configurable and is disabled by default.

Director-specific SNMP traps specified in the custom MIB include Fibre Channel

port operational state changes and FRU operational state changes.

If authorized through the Configure SNMP dialog box in the Element Manager,

users at SNMP management workstations can modify MIB variables.

■ Director modifications performed through SNMP management workstations

are recorded in the associated director audit log and are available through the

Element Manager. For additional information, refer to the HP StorageWorks

SNMP Reference Guide for Directors and Edge Switches.
