Mirror Status Flags

Dbspaces, blobspaces, and sbspaces have status flags that indicate whether they are mirrored or unmirrored.

You must perform a level-0 backup of the root dbspace before mirroring starts.

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 in the process of being recovered

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