PDFs
Use NetApp Workload Factory to simplify managing your block storage resources, including igroups and block devices, and control client access for FSx for ONTAP block devices to provide optimal performance and minimize costs.
From the Workload Factory console, you can manage initiator groups (igroups) to control client access to block devices. You can also view block device details, increase capacity, manage client access, archive data for inactive block devices, and delete block devices.
Check the block storage diagram to check for the following:
-
Client connections
-
Block device status
-
Node-client relationship
-
Potential incorrect client connections
-
You must associate a link to manage igroups. Learn how to associate an existing link or to create and associate a new link. After you associate the link, return to this operation.
-
You must have an existing igroup or block device to view and manage.
