Dell Storage Initialization Wizard Does Not
Register the Cluster Node to the
PowerVault MD3000 Storage Array if a Dummy
Host is Registered
You can register a maximum of two hosts (or cluster nodes) with the
PowerVault MD3000 storage array using the Dell Storage Initialization Wizard.
The wizard does not register additional hosts after two hosts have been
registered. You may encounter an error condition where you are not allowed to
register an additional host even when a single physical host is registered. If you
encounter this error, verify to ensure that a dummy host is not registered.
NOTE: A dummy host is created either when a host is renamed or when an existing
host is turned off. This host is not operational but it is visible to the storage array.
You can delete the dummy host from the storage array using the Dell PowerVault
Modular Disk Storage Manager.
