You can use the CheckProposedNodeAdditions method to test a set of storage nodes to see if you can add them to a storage cluster without errors or best practice violations.


This method has the following input parameter:

Name Description Type Default value Required


A list of storage IP addresses of storage nodes that are ready to be added to a storage cluster.

string array



Return values

This method has the following return values:





Indicates whether or not the proposed storage nodes would make up a valid storage cluster. Possible values:

  • true

  • false



Errors that would occur if a storage cluster was created using the proposed storage nodes. Possible error codes:

  • nodesNoCapacity: Nodes did not have any useable capacity.

  • nodesTooLarge: Nodes constitute too large a portion of cluster capacity for the active protection scheme.

  • nodesConnectFailed: Could not connect to nodes to query hardware configuration.

  • nodesQueryFailed: Could not query nodes for hardware configuration.

  • nodesClusterMember: IP addresses for nodes are already in use in the cluster.

  • nonFipsNodeCapable: Unable to add a non-FIPS capable node to the storage cluster while the FIPS 140-2 drive encryption feature is enabled.

  • nonFipsDrivesCapable: Unable to add a node with non-FIPS-capable drives to the cluster while the FIPS 140-2 drive encryption feature is enabled.
