If the volumes of your database instance are mirrored, one of the volume mirrors may fail. In this case, the database continues to operate but only the part of the volume pair that is intact can be accessed. The faulty volume mirror is displayed as a Bad volume.

You use this function to recover a damaged mirror log volume.

If you trigger the recovery of a log volume, it is only reinitialized. In other words, the data is not copied from the intact volume to the recovered volume. The system then writes to both log volumes sequentially. The volume originally marked BAD must be filled once before the contents of both volumes are identical again and both volumes can be read.

The defective volume remains marked BAD during the entire reintegration phase.

The database instance is the ONLINE or the ADMIN operational state.

1. Choose Instance ® Recovery ® Volumes.
   Select the BAD volumes that are to be recovered.
2. Choose Volumes ® Execute to start initializing the mirror volume.
