Issue 24:
Description
While performing discovery, if a device is discovered using "host name," and if its IP address changes at a
later time, OpenManage Essentials displays two devices after the next discovery cycle. One device
displays the old IP address and status as Power Down, while the other displays the new IP address. This
problem is likely to affect systems that have DNS-DHCP IP addressing and for which the IP addresses
frequently change. [148069]
Resolution
A workaround to eliminate duplicate device is to delete the device with the old IP address.
Issue 25:
Description
The choice of protocols specified for discovering and managing the devices can result in varying levels
of manageability. For instance, if you choose to manage devices in your network using only WMI, the
devices with only SNMP agent (example DRAC) are classified under the "Unknown" group and
consequently, you may not get the Application Launch (example RAC console) functionality for the
device. To avoid such issues, make a careful choice of the protocols while configuring discovery ranges,
keeping in mind the devices (and protocols supported by agents running on those devices) that you are
going to manage. [153729]
Issue 26:
Description
NIC information is not displayed in the device details screen for Dell/EMC arrays.
Resolution
Use Navisphere Manager to view these details.
Issue 27:
Description
If you are managing a Dell/EMC storage array, enter the IP address for only one of the storage processors
(that is, either SPA or SPB, and not both) in the discovery range. The storage processors are redundant
and return the same inventory data to OpenManage Essentials. If you enter both SPs in the discovery
range, only one SP will be displayed in the device tree.
Issue 28:
Description
It is not recommended to provide an IP address in multiple ranges, especially when you are using the
IPMI protocol. This could result in duplicate devices being displayed on the device tree. [78710]
Issue 29:
Description
For IPMI-based discovery or inventory, the maximum length for the host operating system name is 62
characters. Any character beyond this limit will be truncated. [91210]
Issue 30:
Description
SNMP connectivity from Essentials may fail if the SNMP ports on the management station and managed
system are different. If some management applications change the default SNMP port, it could lead to
SNMP connectivity failure from Essentials. [175442]
