IBM Informix OnLine Database Server Administrator’s Guide

When you initiate recovery for a “down” mirrored chunk, a daemon process
begins copying the contents of the primary chunk to the chunk being
recovered. OnLine brings the chunk online if the recovery is successful. The
recovery status (R) is transitional.

If you are logged in as user informix, you can change the status of a mirrored
chunk from within

DB-M

onitor or from the command line. If you are logged

in as root, you must use the command-line options.

You can make this change while OnLine is in online mode.

The following table defines the eight OnLine chunk status flags:

Chunk belongs to a dbspace.

Chunk belongs to a blobspace.

Chunk is down, no reads or writes can occur.

Mirror chunk.

Chunk is online.

Primary chunk.

Chunk is currently being recovered.

New mirror chunk that contains logical log files; a level-0 archive is
needed before the mirror can become active.
