Troubleshooting Device Discovery
If a device discovery is not successful, perform the following steps to
troubleshoot and fix the problem:
1
If the device assigned for discovery is a Dell PowerEdge system, ensure that
Dell OpenManage Server Administrator is installed on it.
2
To discover Windows devices successfully, configure the SNMP services
appropriately. For detailed information on configuring SNMP services on
Windows, see Configuring SNMP Services on Windows.
3
To discover Linux devices successfully, configure the SNMP services
appropriately. For detailed information on configuring SNMP services on
Linux, see Configuring SNMP Services on Linux.
4
After configuring the SNMP services, verify whether the SNMP services
are responding correctly.
5
If the device assigned for discovery is Microsoft Windows and you want to
use WMI, ensure that the user name and password used in the WMI
credentials has the local administrator permissions on the machine that
you want to discover. You can use the Microsoft
wbemtest
utility to ensure
that WMI connectivity to the Windows Server is correct.
6
If the device assigned for discovery is a non-server network device, such as
a printer, Dell PowerConnect switch, and so on, ensure that SNMP is
enabled on the device. You can do this by accessing the Web interface for
a device.
