Replacing a node within a cluster

NAS Platform and Unified Storage Series 4000 Hardware Reference

Part Number

Replacing a single node within a cluster assumes only two-node clusters and the presence of an external SMU, which acts as a quorum device. This helps to simplify the replacement process because a cluster preserves operational state of the entire system beyond any single node failure.

Because you are replacing an existing node from a cluster, you do not require any additional licenses, since the cluster will retain the licenses used from the existing node and the Cluster MAC-ID does not change, even if you are replacing node 1.
