Discovery and Inventory
The processor count in OpenManage Essentials differs for managed systems that contain processors
with multiple cores or HyperThreading enabled. The count differs based on whether the managed
system is discovered using the CIM or SNMP protocol. Systems discovered using SNMP report physical
processors, and the systems discovered using CIM reports logical processors.
Issue 1:
Description
In the OpenManage Essentials GUI, if you attempt to create a discovery range with an IP address ending
in ".0", the following error message is displayed: "The last octet cannot be 0". Depending on the subnet
mask, an IP address ending in ".0" is valid for a device. [48781].
Resolution
To workaround ths issue, import a .csv file with a device IP ending in ".0". OpenManage Essentials
discovers and classifies the device properly using this method.
Issue 2:
Description
If you create a new custom device group with modular servers, and perform another discovery, all the
server objects in that group are lost. [49224]
Resolution
To workaround this issue, do not select the group node for discovery, but rather just the devices within
that group.
Issue 3:
Description
An EqualLogic storage array is displayed even after excluding the EqualLogic discovery range.
Resolution
If the EqualLogic Group Management, EqualLogic Storage Group, and all the EqualLogic member IP
addresses are included in a single discovery range configuration, excluding that range will exclude the
entire group in the device tree.
If these IP addresses are distributed among multiple discovery range configurations, to exclude the
EqualLogic group, all the associated discovery ranges must be excluded.
Issue 4:
Description
For Dell PowerVault MD storage arrays with thin virtual disks, the Virtual Disk Information table in the
OpenManage Essentials device inventory displays the name of the repository for thin provisioning
instead of the thin virtual disk name. [42606]
Issue 5:
Description
For Dell PowerVault MD storage arrays, OpenManage Essentials displays critical health status, even if the
device is in a warning state. [42607]
Issue 6:
Description
The model number for both Dell Force10/Networking C150 and C7004 Ethernet switches is displayed as
C150/C7004 switch in the device inventory. The model number for both Dell Force10/Networking C300
and C7008 Ethernet switches is displayed as C300/C7008 switch in the device inventory. [43443]
