the same configuration can be applied on LVM slice (DiskSuite), also in mirroring configuration.

Also, it's better to flush the cache used by the logging configuration running the “lockfs (1M)”. The option “-f” forces a synchronous flush of the named filesystem. It returns when all data has been written to disk and the log has been rolled.

Using your example:

/usr/sbin/lockfs -f /dev/dsk/c0t0d0s3

Better if insert the command in the crontab for flush log in a specified time every day.
