Maintenance Approach
Whenever possible, the director maintenance approach instructs service personnel
to perform fault isolation and repair procedures without degrading or interrupting
operation of the director, attached devices, or associated applications. Director
fault isolation begins when one or more of the following occur:
■
System event information displays at the attached HAFM application, a
remote workstation communicating with the HAFM appliance, or the
Embedded Web Server (EWS) interface.
■
LEDs on the director front bezel or FRUs illuminate to indicate a hardware
malfunction.
■
An unsolicited SNMP trap message is received at a management workstation,
indicating an operational state change or failure.
■
Notification of a significant system event is received at a designated support
center through an e-mail message or the call-home feature.
System events can be related to one of the following occurrences:
■
Director or HAFM appliance failure (hardware or software).
■
Ethernet LAN communication failure between the director and HAFM
appliance.
■
Link failure between a port and attached device.
■
ISL failure or segmentation of an E_Port.
Fault isolation and service procedures vary, depending on the system event
information provided. Fault isolation and related service information is provided
through maintenance analysis procedures (MAPs) documented in “
Diagnostics ”
on page 33.
MAPs consist of step-by-step procedures that prompt service personnel for
information or describe a specific action to be performed. MAPs provide
information to interpret system event information, isolate a director failure to a
single FRU, remove and replace the failed FRU, and verify director operation.
The fault isolation process normally begins with “ MAP 0000: Start MAP ” on
page 45. When a fault occurs, ensure that the correct director is selected for
service (if the HAFM appliance manages multiple directors or other HP products)
by enabling unit beaconing at the failed director. The amber system error LED on
the director front bezel blinks when beaconing is enabled. Instructions to enable
beaconing are incorporated into the MAP steps.
