If the logs are mirrored, aren't they supposed to be identical??  As in if
your corrupt the data on the primary the identical same corruption will
show up on the secondary copy.  Or are you talking about bad hardware
writes????

Reference:
It looks like ADSM has found a corrupt recovery log.  Are the log files
mirrored?  (More than one copy?)   I've had trouble with ADSM not
checking the secondary copy if it finds a corrupt primary.  If you do
have a second copy of the file, try renaming the first so that ADSM
can't find it.  This will force ADSM to use the secondary.  Once ADSM
is started, you can reformat the first file and add it back.
