The Manual Storage Provisioning email states that I should add more data LUNs than are required. You receive this email when adding a new server to an existing service and one or more of the following applies:
You added a server to a deployed server group using the Add a Server feature.
The servers in the selected group are connected to a shared data disk.
A manual storage provisioning action is required for the data disk.
If you receive this email, you must add the LUN information to both the new server and the existing servers. You only need to add the LUN information to the VSE storage pool entry for the new server.
