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, see the description of the onstat -d option in the HCL Informix® Administrator's Reference. For information about how to display these status flags, see Monitor disk usage.
