Using SNMP

This appendix provides an overview for using SNMP with Sun Storage Common Array Manager.

The array management software provides SNMP traps as well as an agent that can be queried.

SNMP Traps

Sun Storage Common Array Manager provides SNMP traps for all actionable events. The trap fields are defined by the SNMP trap MIB (see SNMP Trap MIB).

The traps that can be received are based on the alarms possible for the specific device. Traps are sent through port 162 to the IP addresses configured in the user interface (UI) or command-line interface (CLI). The minimum alarm priority used for trap generation can be selected using UI or CLI interfaces. Traps can only be sent to the default ’public’ community at this time.

Sun Storage Common Array Manager does not provide an SNMP agent that can be queried using SNMP ’GET’ operations. At times, the devices themselves support SNMP ’GET’ operations although all the arrays supported by the array management software at this time do not. Instead customers typically do remote scripting using the remote CLI (SSCS) or the SMI-S industry standard provider is used.
