The following Infrastructure Validations show Failed status when choosing to deploy a greenfield Aria Operations for Logs environment after filling out and selecting all of the correct variables and running the pre-check:
Along with the following Warning status:
Aria Suite Lifecycle Manager 8.18.x
Aria Operations for Logs 8.x
This can be caused by the inventory not being synced between the vCenter and Aria Suite Lifecycle Manager.
The desired data center may have been renamed since the last Aria Suite Lifecycle Manager inventory sync to the desired vCenter, pay attention to the Component / Resource column and compare it to the actual names in the vCenter inventory. To confirm if the inventory sync is a good step: it does not show the same name in the Component / Resources column as currently in vCenter, even though it lets you select the correct data center in the previous steps.
