director 2/64 service manual 1–27
General Information
This publication provides instructions for director fault isolation using the Embedded
Web Server interface. See Diagnostics on page 2–1 for the fault isolation tasks.
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 server.
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 customer personnel 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 Product Manager
application, users at SNMP management workstations can modify MIB variables.
• Director modifications performed through SNMP management work stations are
recorded in the associated director audit log and are available through the Product
Manager application. For additional information, refer to the hp StorageWorks
SNMP reference guide for directors and edge switches.
E-Mail and Call-Home Support
If e-mail notification and call-home support are configured for the director as part of
the customer support process, service personnel may be:
• Notified of a director problem by e-mail message, either directly or through a
system administrator at the customer site or call center.
