Symptoms

After upgrade to Oracle Hardware Management Pack (OHMP) version 2.4.1, SNMP access fails.

# head /var/log/snmpd.log
NET-SNMP version 5.0.9
no connection to sunHwMonMIB agent
no connection to sunHwMonMIB agent
no connection to sunHwMonMIB agent

Cause

OHMP 2.4.1 disables all OHMP SNMP features by default because of Oracle Security directives, as v2c is not considered to be a secure protocol. There is no support for V3.

Solution

Customers using SNMP on OHMP 2.4.1 will have to manually enable SNMP functionality by doing the following:

Edit /etc/ssm/hwmgmtd.conf. Change the following 2 lines:

#inventory_poller_enabled=0
#request_thread_enabled=0

inventory_poller_enabled=1
request_thread_enabled=1

Then restart sp/management service and snmpd services. After initialization (which will take around 5 minutes) OHMP SNMP functionality should be available again.
