What does HRESULT 0x400D0197 (NS_I_RESTRIPE_CUB_OUT) mean?

NS_I_RESTRIPE_CUB_OUT

NS_I_RESTRIPE_CUB_OUT — 0x400D0197

This result belongs to Content Server removal by restriping not to a generic restart checklist, because a Content Server was removed from the active stripe topology after its content responsibilities were redistributed.

The contract behind the code

Restriping redistributes media-server placement and ownership across disks or Content Servers. In the context of Content Server removal by restriping, it is a coordinated topology operation rather than a generic filesystem optimization, so pre/post stripe maps, peer identity, capacity, and representative media reads are the relevant evidence. Locate the first component that changes state and distinguish later summary errors.

Important distinction. Being restriped out is not the same as a server crash; it is a coordinated topology outcome that should leave no active ownership.

Diagnostic worksheet

• Server name/UID, operation ID, disks owned by the server, and final peer topology
• Content and sessions migrated away from the server
• Remaining links, management records, and routing entries that reference it
• Shutdown or decommission plan following the restripe

Useful comparisons

• Verify every peer reports the server absent from the final stripe map. Keep media bytes, server identity, and unrelated publishing-point settings fixed.
• Serve content previously owned by the removed server from surviving peers. Use a disposable publishing point or maintenance window when the test can alter server or storage state.
• Restart a surviving peer and confirm the old UID is not reintroduced. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of the reported failure.

Read the result in context

When a minimal control succeeds, the failure is tied to the original object or its state rather than to the whole Windows subsystem. When the control fails identically, preserve host-level evidence first. If a different code appears, diagnose that new failure separately rather than treating it as automatic success.

Also check severity: informational and warning values are observations or policy notifications and should be routed differently from a failure HRESULT even when an event viewer labels the source generically.

A defensible fix

Correction: Remove stale peer and management records only after verifying content relocation and client routing.

Accept the repair only when surviving servers agree on topology, clients receive the relocated content, and the removed server can remain offline without repair events.
