Managing and Recovering a Remote System
Answer
As part of discovery, IT Assistant attempts to verify
the get and set community names of the device.
In IT Assistant, you have the get community
name = public and the set community name = private.
By default, the community name for the DRAC 4
agent is public. When IT Assistant sends out a set
request, the DRAC 4 agent generates the SNMP
authentication error because it will only accept
requests from community = public.
You can change the DRAC 4 community name
using the racadm CLI.
To see the DRAC 4 community name, use the
following command:
racadm getconfig -g cfgOobSnmp
To set the DRAC 4 community name, use the
following command:
racadm config -g cfgOobSnmp -o
cfgOobSnmpAgentCommunity
< community name >
To prevent SNMP authentication traps from being
generated, you must input community names that
will be accepted by the agent. Since the DRAC 4
only allows one community name, you must input
the same get and set community name for IT
Assistant discovery setup.
It may take several minutes for the remote racadm
services and the Web-based interface to become
available again after a reset of the DRAC 4 Web server
The DRAC 4 Web server is reset after the
following occurrences:
• When the cfgRacTuneHttpsPort property is
changed (including when a config -f <config file>
changes it)
• When racresetcfg is used
• When the DRAC 4 is reset
