SetProtectionDomainLayout

Contributors netapp-pcarriga netapp-dbagwell

You can use the SetProtectionDomainLayout method to assign nodes to custom protection domains.

Information must be provided for all active nodes in the cluster and no information can be provided for inactive nodes. All nodes in a given chassis must be assigned to the same custom protection domain. The same protectionDomainType must be supplied for all nodes. protectionDomainTypes that are not custom, such as node and chassis, should not be included. If either of these are provided, then the custom protection domains are ignored and an appropriate error is returned.

Note Custom protection domains are not supported with the following configurations:

  • Storage clusters containing shared chassis

  • Two-node storage clusters

The method returns an error when used on storage clusters with these configurations.
