HP Storage Essentials V5.00.01 installation guide (T4283-96011, January 2006)

Discovering Filers, Tape Libraries, Switches and Storage Systems56
before discovering any McDATA switches. If you must change the configuration, see ”(Discovery
from HP SE only) Changing the Discovery Settings” on page 64.
• 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 99.
• 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 67.
• 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 59. EFC Manager versions
7.0 and 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.
