General Information
• System event information displays at the SANpilot interface.
• LEDs on the switch front panel or adjacent to Fibre Channel ports
illuminate to indicate a hardware malfunction.
• An unsolicited SNMP trap message is received at a management
workstation, indicating an operational state change or failure.
System events can be related to a:
• Switch failure (hardware or software).
• Ethernet LAN communication failure between the switch and a
PC accessing the SANpilot interface.
• 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 Chapter 3. 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 switch failure, repair the
switch, and verify switch operation. The fault isolation process
normally begins with MAP 0000: Start MAP on page 3-6.
Ensure the correct switch is selected for service by enabling unit
beaconing at the failed switch. The amber system error (ERR) LED on
the switch front panel blinks when beaconing is enabled. Instructions
to enable beaconing are incorporated into MAP steps.
Switch Management
The switch is managed and controlled through a customer-supplied
PC platform with an Internet connection to the SANpilot interface on
the switch. Using this graphical user interface (GUI), operators can
quickly view switch status. The interface also allows service
personnel to perform configuration tasks, view system alerts and
related log information, and monitor switch status, port status, and
performance. FRU status and system alert information are highly
visible.
