If you are running the log spaces of a database instance in mirrored form, and a log devspace fails while the database is running, there are functions available that enable you to recover the failed devspace.
Entries that were written to the intact devspace only while the damaged devspace was out of action are not copied.
Note that the mirrored log devspace is only secure once the recovered devspace is operating again. You should therefore backup the log entries that only exist once using a log backup (
