70 Sun StorEdge 3900 and 6900 Series Troubleshooting Guide — March 2002
Virtualization Engine Diagnostics
The virtualization engine monitors the following components:
■ Virtualization engine router
■ Sun StorEdge T3+ array
■ Cabling among the router and storage
Service Request Numbers
The service request numbers are used to inform the user of storage subsystem
activities.
Service and Diagnostic Codes
The virtualization engine’s service and diagnostic codes inform the user of
subsystem activities. The codes are presented as a LED readout. See Appendix
A for
the table of codes and actions to take. In some cases, you might not be able to receive
Service Request Numbers (SRNs) because of communication errors. If this occurs,
you must read the virtualization engine LEDs to determine the problem.
▼ To Retrieve Service Information
You can retrieve service information in two ways:
■ CLI Interface
■ Error Log Analysis Commands
Both of these methods are described in the following sections.
CLI Interface
The SLIC daemon, which runs on the Storage Service Processor, communicates with
the virtualization engine. The SLIC daemon periodically polls the virtualization
engine for all subsystem errors and for topology changes. It then passes this
information in the form of an SRN to the Error Log file.
