Overall health status shows warning or critical while health status of node
components shows healthy
The overall health status of PowerEdge servers, failover clusters, and HCI clusters might be displayed as critical or warning even
if the components of the nodes displayed on the Windows Admin Center are healthy. Because the health status of physical disks
that are attached to embedded SATA controller may be displayed as Unknown as iDRAC is unable to get the health information
for these disks.
For more details on the components in critical health state, go to the respective iDRAC console.
Unable to create users on target iDRAC device
If the lockdown mode is enabled on YX4X model of PowerEdge Servers and above, inventory of health, hardware, and iDRAC
fails with the error: “Unable to create users on target iDRAC device.”
Resolution: Disable the lockdown mode on the target node managed by Dell EMC OpenManage Integration.
Unable to initialize the OMIMSWAC extension.
Retrieving inventory from servers and cluster nodes may fail with the error: Unable to initialize the OMIMSWAC extension.
Resolution: Ensure the IPMI driver is installed, and the IPMI service is running on the target node. For more information on the
requirement and solution, see Dell information center.
Why is the Inventory details not displayed?
If inventory details are not loading, ensure the followings:
● Target node is not in the reboot state and is powered on.
● Firewall is not blocking communication through SMB port 445. For more information, see prepare your environment for
Windows Admin Center.
● The USB NIC adapter is not disabled on the target node operating system.
● Before you launch Dell EMC OpenManage Integration extension in Windows Admin Center, ensure to log in to WAC as a
gateway administrator.
● PS-Remoting is enabled.
● Redfish service is enabled on the target node.
● An iDRAC user slot is available on the target node.
● Lifecycle Controller is available on the target node.
● The lockdown mode is disabled on target node.
● The PowerShell execution policy is set to RemoteSigned on the system with Windows Admin Center installed and on
the target node OS. For more information, see https://www.dell.com/support/article/sln318718/dell-emc-openmanage-
integration-with-microsoft-windows-admin-center-omimswac-fails-to-query-host-information.
● IPMI drivers are present in the target node and the IPMI service is running.
● There is no IP address conflict in USB pass-through .
● There are no proxy settings configured on the target node that might conflict with the USB NIC IP address configured in OS
to iDRAC Pass-through in the iDRAC. If the proxy setting is configured, do the following to exclude the USB NIC IP address:
1. In the target node, open the Proxy settings.
2. Under Manual proxy setup, type 169.254.* to exclude the USB NIC IP address configured in the OS to iDRAC
Pass-through settings.
● CA and CN are disabled on the target node iDRAC.
Why is the inventory details not displayed for a few of the cluster nodes?
While monitoring Storage Spaces Direct cluster using OMIMSWAC extension, the inventory and health data for few of the
servers may not load. In this case, reset the iDRAC and rerun the inventory/health data.
