Virtualization Engine Diagnostics; Service Request Numbers; Service And Diagnostic Codes; To Retrieve Service Information - Sun Microsystems StorEdge 3900 Series Troubleshooting Manual

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
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.
