Mirror Status Flags

Dbspaces have status flags that indicate whether it is mirrored, unmirrored, or newly mirrored.

You must perform a level-0 backup of the root dbspace before mirroring starts for any dbspace containing log files.

Chunks have status flags that indicate the following information:

• Whether the chunk is a primary or mirror chunk
• Whether the chunk is currently online, down, a new mirror chunk that requires a level-0 backup of the root dbspace, or being recovered

For descriptions of these chunk status flags, refer to the description of the onstat -d option in the utilities chapter of the IBM Informix: Administrator's Reference. For information on how to display these status flags, refer to Monitoring Disk Usage.
