Installation Manual

Discovering Switches, Storage Systems, NAS Devices, and Tape Libraries130
1. Make sure there are no port conflicts for receiving SNMP traps. When the management server
is configured to contact the proxy by SNMP, it receives events from the proxy in the form of
SNMP traps. By default, the management server uses port 162 to receive SNMP traps. If
another software package is using that port, the management server is unable to receive the
traps. For information about changing the port, see ”Changing the SNMP Trap Listener Port
and Community String for Switches Discovered with SNMP” on page 133.
2. Set up the proxy to send traps to the correct port. When you are using the SNMP setting to
discover a proxy, you must configure the SNMP agent on the proxy manager to send traps to
the management server using the port you selected. This configuration then sends traps from all
switches managed by that proxy. See the proxy documentation for more information.
NOTE: The management server uses the Windows SNMP trap service when you run HP
SIM and HP Storage Essentials on a Windows server or when the property
cimom.winsnmpTrapService=true is set. The Windows SNMP trap service is not used
on Solaris servers.
3. Enter the following information in HP SIM
• The IP address or system name of the switch you want to discover.
• The user name for accessing the switch. The default user name is public (the read-only
community string).
• Enter anything as a password; HP SIM does not allow an empty password field.
Changing the Discovery Settings
To change the discovery settings for McDATA and Connectrix switches:
1. If you have already discovered your switches, delete all McDATA and Connectrix switches as
described in ”Deleting Discovered Elements” on page 164.
2. Select Options > Storage Essentials > Manage Product Health, and click Advanced in the Disk
Space tree.
3. Click Show Default Properties at the bottom of the page.
To enable SNMP:
a. Uncomment the cimom.useSnmpMcDataProvider property by removing the pound sign
(#) in front of it.
b. Change the cimom.mcdata.dontUseSmis property as follows:
cimom.mcdata.dontUseSmis=true
NOTE: The cimom.mcdata.dontUseSmis property exists only in upgrade installations.
If the property does not exist on your system, enter it manually.
To enable SWAPI:
a. Comment out the cimom.useSnmpMcDataProvider property by placing a pound sign
(#) in front of it.
