Procedure documentation Recovering a Damaged Volume Locate the document in its SAP Library structure

Use

If you are running the log volumes of a database instance in mirrored form, and a single log volume fails while the database is running, there are functions available that enable you to recover the failed volume. With this command, you return a damaged volume of a volume pair to operation.

Note

Entries that were written to the intact volume only while the damaged volume was out of action are not copied.

Note that the mirrored log volume is only secure once the recovered volume is operating again. You should therefore backup the log entries that only exist once using a log backup (Backing up the Database Instance).

Prerequisites

·        You have the server authorization Recovery.

·        You are operating the database instance with mirrored log volumes. (LOG_MODE: DUAL).

·        You have opened a database session (see: Opening a Database Session).

·        You have executed the command for restoring a database instance.
