SNMP authentication
Why is the message 'Remote Access: SNMP Authentication Failure' displayed?
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 SNMP agent community name for
iDRAC agent is public. When IT Assistant sends out a set request, the iDRAC agent generates the SNMP authentication error
because it accepts requests only from community = public.
To prevent SNMP authentication errors from being generated, you must enter community names that are accepted by the
agent. Since the iDRAC only allows one community name, you must use the same get and set community name for IT Assistant
discovery setup.
Storage devices
Information for all the storage devices connected to the system are not displayed and OpenManage Storage
Management displays more storage devices that iDRAC. Why?
iDRAC displays information for only the Comprehensive Embedded Management (CEM) supported devices.
