before discovering any McDATA switches. If you must change the configuration, see ”(Discovery from HP SE only) Changing the Discovery Settings” on page 50.

•After you discover a McDATA or Connectrix switch through a proxy, the IP address displayed next to the name of the switch is actually the IP address of the proxy for the switch in the Discovery, and Get Details screens. To find the IP address of the switch, click the link for the switch in the Topology screen (Tools > Storage Essentials > Home > Discovery > Topology), Discovery Data Collection screen (Options > Storage Essentials > Discovery > Run Discovery Data Collection), or Get Details screen (Tools > Storage Essentials > Home > Discovery > Details) and then click the Properties tab. The Properties tab can also be accessed by double clicking the switch in System Manager.

•If you want to add, remove, or replace McDATA or Connectrix switches after you have discovered the service processor, you must perform additional steps, see ”About Managing McDATA and EMC Connectrix Switches” on page 85.

•If you have problems obtaining information from McDATA or Connectrix switches during discovery and/or Get Details (Discovery Data Collection for HP SIM), see ”Step 2 - Discover Storage Systems, Filers and Tape Libraries” on page 53.

•All McDATA switches in a fabric must be managed by the same EFC Manager. Do not have more than one EFC Manager to a fabric for McDATA switches. If you do use more than one EFC Manager in a fabric, you must use the same EFC Manager for your zoning. Do not use the other EFC Managers for zoning, as this will create zoning database problems.

•All Connectrix switches in a fabric must be managed by the same Connectrix Manager. Do not have more than one Connectrix Manager to a fabric for Connectrix switches. If you do use more than one Connectrix Manager in a fabric, you must use the same Connectrix Manager for your zoning. Do not use the other Connectrix Managers for zoning, as this will create zoning database problems.

•If you want the management server to receive SNMP events from Connectrix or McDATA switches, do one of the following:

•If you discovered Connectrix Manager or EFC Manager, only enable SNMP trap forwarding to the management server on the Connectrix Manager or EFC Manager, not on the individual switches.Connectrix Manager or EFC Manager should be configured to forward SNMP traps to the IP address of the management server, and the community string should match the user ID you used to discover Connectrix Manager or EFC Manager.

•If you discovered Connectrix or McDATA switches directly, enable SNMP trap forwarding on the switches, not on any other management software. The switches should be configured to forward SNMP traps to the IP address of the management server, and the community string should match the user ID you used to discover the Connectrix or McDATA switches.

SWAPI Setting Through a Proxy

With the SWAPI setting, the management server contacts a proxy to obtain information about the switches connected to it. Use Enterprise Fabric Connectivity (EFC) Manager for this option. If you do not have EFC Manager, see ”SNMP Setting Through a Proxy” on page 45. EFC Manager versions

7.0and later can communicate with the management server and the switch. EFC Manager accesses the switch through a SWAPI connection. This configuration lets multiple instances of the management server or other clients contact EFC Manager, which in turn provides information about the switch.
