Dirty region logging guidelines

Dirty region logging (DRL) can speed up recovery of mirrored volumes following a system crash. When DRL is enabled, Veritas Volume Manager keeps track of the regions within a volume that have changed as a result of writes to a plex.

Warning: Using Dirty Region Logging can adversely impact system performance in a write-intensive environment.

See "Dirty region logging" on page 59.
