Sun Microsystems 3900, 6900 manual Virtualization Engine Diagnostics, Service Request Numbers SRNs

Virtualization Engine Diagnostics

The virtualization engine monitors the following components:

■Virtualization engine router

■Sun StorEdge T3+ array

■Cabling between the router and the storage

Service Request Numbers (SRNs)

SRNs 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 light-emitting diode (LED) readout. See Appendix A for the table of codes and related appropriate actions to take. In some cases, you might not be able to receive SRNs because of communication errors. If this occurs, you must read the virtualization engine LEDs to determine the problem.

Retrieving Service Information

You can retrieve service information from one of two sources:

■CLI Interface

■Error Log Analysis Commands

Both of these sources are described in the following sections.

CLI Interface

The Serial Loop Intraconnect (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 topology changes. It then passes this information, in the form of a SRN, to the Error Log file.
