The database server sends the following message to the message log when a disabling I/O error occurs:
Assert Failed: Chunk {chunk-number} is being taken OFFLINE.
Who: Description of user/session/thread running at the time
Result: State of the affected database server entity
Action: What action the database server administrator should take
See Also: DUMPDIR/af.uniqid containing more diagnostics
The result and action depend on the current setting of ONDBSPACEDOWN, as described in the following table.
| ONDBSPACEDOWN Setting | Result | Action |
|---|---|---|
| 0 | Dbspace {space_name} is disabled. | Restore dbspace {space_name}. |
| Blobspace {space_name} is disabled. | Restore blobspace {space_name}. | |
| 1 | The database server must stop. | Shut down and restart the database server. |
| 2 | The database server blocks at next checkpoint. | Use onmode -k to shut down, or use onmode -O to override. |
