Each site in a StorageGRID Webscale deployment can include one or more Admin Nodes. If a deployment includes multiple Admin Nodes, you must configure one Admin Node as the preferred sender of notifications and AutoSupport messages. You can select any Admin Node as the preferred sender, and you can change which Admin Node is selected at any time.
The
page lists the Admin Node that is currently sending notifications. In most cases, this Admin Node is the same as the Preferred Sender; however, if an Admin Node is islanded from the rest of the system, it is unable to use the Preferred Sender and automatically updates to become the Current Sender. In the case of islanded Admin Nodes, multiple Admin Nodes will attempt to send notifications and AutoSupport message and thus it is possible that multiple copies of notifications will be received.
