Verify license information
In OMIMSWAC, you can view nodes details and their licenses from the iDRAC inventory. To view the iDRAC inventory of a
target node
1. In Windows Admin Center, connect to a server or cluster.
2. In the left pane of Windows Admin Center, under EXTENSIONS, click Dell EMC OpenManage Integration, and then
navigate to the iDRAC tab.
3. Under iDRAC tab, you can verify the OMIWAC Premium License available on the target nodes.
NOTE:
All nodes participating in the managed cluster must have OMIWAC Premium License installed to use premium
features. If any of the cluster nodes are not licensed, OMIMSWAC notifies and does not allow you to use the premium
feature.
Credential Security Service Provider (CredSSP)
To perform any cluster operation such as Clustered-Aware Updating (CAU) using OMIMSWAC, as per Microsoft Windows
Admin Center recommendation, CredSSP needs to be enabled. The extension, when required, will prompt to enable the
CredSSP. Click Yes to enable the CredSSP to continue with the operation.
OMIMSWAC extension uses the MS WAC framework API to enable the CredSSP as follow:
1. Enables the client role in the Gateway system.
2. Enables the server role in each of the node.
For more information on CredSSP, see https://docs.microsoft.com/en-us/windows/win32/secauthn/credential-security-
support-provider.
When cluster is not in use, it is recommended to disable the credssp.
OS to iDRAC Pass through
While fetching inventory from the target node, OMIMSWAC extension enables the OS-to-iDRAC pass through for the very first
time, if it is not enabled.
