There are three methods of TSM 6 log mirroring. What are their pros and
cons?

 1. TSM/DB2 Active Log Mirror in software
 2. Hardware Array Mirroring (RAID1/RAID10)
 3. OS such as AIX LVM mirroring

I know that in Version 5, TSM software log mirroring provided somewhat
better recoverability compared to the other two methods. Is that still
true in Version 6? Or should I just go with hardware RAID.
