24 Dell OpenManage Plug- in Version 2.0 for Oracle Enterprise Manager 12c | A00
7.3 Target is not available
There are several possible reasons for a Dell OpenManage plug- in target to have a down status. Most
often the reason for the OpenManage plug- in for OEM target to have a down status is due to an error
during configuration. When configuring the plug- in, ensure that you have verified all credentials that are
used to connect to the Dell OpenManage Essentials system. If any of these credentials are incorrect, the
plug- in target will go into a down status until rectified.
7.4 Automatic association between database and server is not
working
For the plug- in to create automatic server- to-database associations, it is recommended to discover the
target running Linux operating system using SSH protocol and iDRAC using WS- Man protocol, and/or
discover the target running Windows operating system using WMI protocol and iDRAC using WS- Man in
OpenManage Essentials. If OMSA is installed on the target operating system, SNMP protocol can be used
instead of SSH/WMI protocol. In PowerEdge server generations prior to 11G, WS- Man protocol is not
supported for iDRAC; SNMP protocol must be used instead.
Note that the servers discovered in OpenManage Essentials are linked to database targets by the plug- in
based on host name. If the host name of the target is different between OpenManage Essentials and the
plug- in, the two targets must be linked manually by the user. It is recommended that all servers are
registered in DNS and that the DNS name resolution option (selected by default) in OpenManage
Essentials is used.
7.5 A device with a name that duplicates a name of another device is
not discovered
OpenManage Plug- in for OEM 12c is designed to monitor an OpenManage Essentials environment where
each device has a unique device name. If there are devices that exist in the environment with duplicate
names, the plug- in will only discover the first of the duplicate devices (ordered by the ID assigned in Dell
OpenManage Essentials).
If it is confirmed that there are multiple devices with matching device names, contact your administrator
to modify these names within OpenManage Essentials. After the device names have been modified, run
the auto discovery process again for the plug- in. The auto discovery process will find the newly named
devices that are also available for promotion.
