Obtaining SNMP Traps using Command View EVA

You must configure Command View EVA so it can send SNMP traps from the EVA to HP Storage Essentials. When the management server receives these SNMP traps, it converts them to WBEM Indications for display in its Event Manager. HP Storage Essentials then forwards the events to HP SIM's event console.

Community String Requirements

•The default community string for Command View EVA 6.x is Public and the default community string for HP Storage Essentials is public. The community strings must be a case-sensitive match, so if you are using the default values in HP Storage Essentials and Command View EVA 6.x, you must change the community strings to a case-sensitive match.

•If you are using the default community strings for Command View EVA 7.x and HP Storage Essentials, no changes to the community strings are needed. If you change the community strings to non-default values, then they must be a case-sensitive match.

CAUTION: Other applications (such as HP SIM) may be using the default community strings to communicate with Command View EVA. If you change the community string in Command View EVA, you might break Command View EVA’s connection to other applications. If a change is needed, we recommend changing the community string in Storage Essentials to match the string in Command View EVA.
