Discovery Data Collection), 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 ”Managing McDATA and EMC Connectrix Switches” on page 132.

•All McDATA or Connectrix switches in a fabric must be managed by the same EFC Manager or Connectrix Manager. Do not have more than one EFC Manager or Connectrix Manager to a fabric for McDATA or Connectrix switches.

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

•If you discovered Connectrix Manager or EFC Manager, enable SNMP trap forwarding to the management server only on the Connectrix Manager or EFC Manager, not on the individual switches.

•If you discovered Connectrix or McDATA switches directly, enable SNMP trap forwarding on the switches, not in any other management software.

•For more information about the SNMP port and community string, see ”Changing the SNMP Trap Listener Port and Community String for Switches Discovered with SNMP” on page 133.

Discovering McDATA and Connectrix switches with SMI-S

Before you can discover McDATA and Connectrix switches with SMI-S, you must download and install the McDATA SMI-S provider software. See the document HP StorageWorks M-Seriesat: http://www.hp.com/go/hpsim/providers for instructions. Check this web site periodically to verify that you are running a current version of the SMI-S provider.

Note the following when discovering these switches with SMI-S:

•Before attempting to discover your switches, ensure that EFC Manager or Connectrix Manager is installed and configured or add your switches to the SMI-S provider.

•For upgrades only: To migrate your existing switches to SMI-S, follow the procedure in ”Changing the Discovery Settings” on page 130.

•Discovering McDATA and Connectrix switches with SMI-S is the default setting. To view or change the discovery settings, see ”Changing the Discovery Settings” on page 130.

•You can install only one instance of the SMI-S provider on the HP Storage Essentials management station.

•Installation of the McDATA SMI-S provider is not supported on Linux systems.

•A McDATA or Connectrix switch cannot be managed by more than one SMI-S provider.

•When you install the SMI-S provider, there are two modes:

•In coexist mode the SMI-S provider communicates with EFC Manager or Connectrix Manager and adds all the switches in the managed list of EFC Manager or Connectrix Manager.

•In direct mode, you must add each switch to the SMI-S provider with its IP address, credentials and switch type. You can use a McDATA’s manageswitch.bat file to manage the addition and deletion of switches.
