> h3. Root cause
> {{waitForDnToReachPersistedOpState}} polls {{getPersistedOpState()}} on the
> {{DatanodeDetails}} object it is given. The test passes {{dn}}, captured from
> {{nm.getNode(dnID)}} before the datanode restarts. When a restarted datanode
> re-registers with a different port set, {{SCMNodeManager#register}} replaces
> the stored {{DatanodeInfo}} (the {{portsChanged}} path added by HDDS-12991).
> In the failing run the HTTP port was missing from the initial registration
> and present on re-registration:
> {noformat}
> SCMNodeManager - Updating ports for registered datanode ca3c16ee-...:
> [STANDALONE=15350, ..., CLIENT_RPC=15349] -> [STANDALONE=15350, ...,
> HTTP=15348, CLIENT_RPC=15349]
> {noformat}
> After that SCM updates the persisted state on the new object (the log shows
> {{IN_MAINTENANCE -> IN_SERVICE}}), while the test keeps polling the stale
> {{dn}} until it times out. The neighbouring assertions already use {{newDn}}.
> {{testNodeWithOpenPipelineCanBeDecommissionedAndRecommissioned}} has the same
> stale reference ({{toDecommission}}) after a restart.
> h3. Fix
> Look up the node from {{NodeManager}} after the restart ({{newDn}} /
> {{nm.getNode(dnID)}}) before waiting for the persisted state.
